Abstract:

Refinery feedstock includes blends of several crude oils, referenced as crude slates. The opportunity for use of wider diversity of lower cost crude slates, including fractions of opportunity and heavy crudes, is often hampered by efficiency limitations of the installed desalters. Many refineries are thus feedstock constrained by the design of their desalter trains and must purchase higher cost crude oil with lower impurity levels. The desalter train variations include: single stage or two stage desalting inter-stage and intra-stage wash water recycle. We present an improved refinery desalting technology based on late R&D and advancements in electrostatic desalter designs. This technology has been deployed in several refineries and demonstrated much improved crude slate desalting efficiency. The basis for this technology includes amplitude modulated electrostatic fields, improved fluid distribution and wash water mixing, enabling refiners to process a greater diversity of crude slates. We provide: An overview of the refinery desalting process and associated challenges with desalting crude slates containing higher fractions of opportunity and heavy crude oils an explanation of the improved desalter technology, including process benefits case studies demonstrating improved desalting and greater feedstock diversity for several refineries.

Abstract:

Ignition improver additives are used to improve the ignition quality, or reduce the ignition delay; i.e. the time between when fuel is injected and time when combustion start is different this difference in time is minimize by additive is called Cetane Improver (CN). The CN is the most widely accepted measure of ignition quality.to get desired value of CN some additive are used hence ignition improvers are usually characterized by the fact that at what extenet they can increase CN. By increasing CN we have two benefits that it helps smoother combustion and lower emissions. Fuel properties are always considered as one of the main factors to diesel engines concerning performance of cetane improver. There are still challenges for researchers to identify the most correlating and non-correlating fuel properties and their effects on cetane improver .In this study to derive the most un-correlating and correlating properties. In parallel, sensitivity analysis was performed for the fuel properties as well as to effect on performance of cetane improver.

There is no published research done on the characterization of the Sudanese Vacuum Residue (VR) in spite of its importance for refinery economics. This article represents an experimental study using n-pentane as supercritical fluid for the fractionation of residue sample taken from a Sudanese refinery. Two kilograms of the refinery residue was fractionated with n-pentane as supercritical solvent (the critical temperature of n-pentane is 469.6 K and the critical pressure, 3.37 MPa). The recirculation rate of n-pentane was set at 60 ml/min. The extraction and fractionation sections of the supercritical fluid extraction unit were maintained at 200 °C and 210 °C, respectively. The pressure of the SFEF unit was initially set at 4 MPa and was increased to 12 MPa over 8 hours. Molecular weight and specific gravity of each narrow-cut were measured and used as the group composition. The bases for selecting these two properties are that they are easily measured and readily available in public domain. The density, Conradson Carbon Residue (CCR) and SARA (Saturates, Aromatics, Resins, Asphaltene) of the sample were measured. After extraction and fractionation the fractions were further analyzed and characterized. Characteristics of supercritical fluids such as carbon dioxide, water are given. It shows the equipment used for supercritical fractionation of the crude oil where the operating pressure is regulated between 4 Mpa to 12 Mpa maximum. The temperature of the supercritical fluid is kept constant at 200 °C. The analysis and characterization of the sample and the quality of the fractions can be used by the refinery to determine the most optimum processing scheme in order to maintain peak performance by controlling the product quality fed to the downstream units.

Abstract:

This work investigates the effect of summer weather conditions on the environmental impact of an Open Cycle Gas Turbine in Abu Dhabi (UAE) using an exergoenvironmental analysis. The results are used to suggest measures for reducing the calculated impact. Actual operational data are verified with simulation data using commercial software. Compared to standard weather conditions, the summer weather conditions decrease the overall exergetic efficiency of the plant by 4.3% and increase the total environmental impact per generated KWh by 7.9%. The addition of a heat recovery steam generator could increase the net power output and decrease the total environmental impact of the plant. The main contributor to the environmental impact of energy destruction is the combustor. Summer conditions increase this impact by 21.5%. The compressor has the second highest environmental impact, increased by 14.6% for summer conditions. A process control system for continuous measurement of exhausted O₂ and CO can help to reduce the excess air and, consequently, the associated environmental impact. This may also decrease the power required by the compressor. Lastly, a cooling system for the ambient air may also help to increase the power output of the plant by decreasing the power required by the compressor.

Abstract:

Studies on electric mobility are mainly on the focus on consumption in situ and assuming environmentally friend electricity. The present paper takes a closer look on the primary energy mix on the electricity production, using different periods of the day. Studies on electric mobility assume consumer reaction to price is rigid and consumers respond by the same mimics. The present paper uses assumptions based on real life effects and adequate consumer behaviors. The results obtained and the related considerations conflicts with main stream studies on the area. Studies on electric mobility assume electricity production dispatch is similar no matter volume of energy transactions. The present study changes the study from power to energy, bringing a closer approach to the marginal cost of production and the dispatch solution. It was possible to conclude that electricity mobility in Portugal is environmentally harmful, economical expensive and energetically unstable. The studies are made based on the present legislation, implemented status quo and foresee goals.

Abstract:

The combustion of fuel causes pollution to the environment due to the sulfur in fuel oils, which forms different sulfur oxides (SOx) during combustion. To minimize the emission of these gaseous pollutants, increasingly strict regulations are being imposed on oil refineries to reduce the sulfur content to a very low limit, around 10-30 ppm. Traditional hydrodesulfurization process reduces the sulfur content in fuel oils; however, the complete removal of sulfur compounds is not possible due to technical and economic reasons. Nevertheless, the recent developments in environmental legalization are moving us towards a world of sulfur-free fuel oils so it becomes necessary to explore alternative desulfurization approaches. Among all different processes, extractive desulfurization appears to be specially promising and the research efforts over the last years focuses on finding the most suitable solvent for the desulfurization process. Among different possible solvents, ionic liquids (ILs) and deep eutectic solvents (DESs) have a great potential to be used in extractive desulfurization process. These solvents have favorable physiochemical characteristics, e.g. low volatility, biodegradability, high thermal stability, ability to dissolve polar and non-polar compounds, etc. In this work, the removal of different sulfuric compounds from fuel using ILs and DESs will be critically reviewed. The effect of structure of ILs, DESs, and the sulfuric compound on the extraction efficiency and selectivity will be investigated. In addition, the different processes for recycling the solvents will be discussed.

Abstract:

Most of the Russian refineries’ facilities have a significant potential to increase productivity, to reduce energy consumption and to improve quality. Existence of such reserves is due to the current practice of autonomous design, when each of the departments (technological, instrumentation, mechanical, etc.) develops only its part and is not able to look at the whole process. Inconsistency generates non-fitment in the project and leads to failures in achieving a goal set, and, consequently, to lost profits.To eliminate such inconsistencies, the system approach is preferred as the most rational among the other methods to increase efficiency, since it can be implemented with the use of actual operating equipment, i.e. does not require large-scale reconstruction or major circuit changes. Thus, a high economic effect is achieved with minimum capital and operating costs.A fundamentally important point is to identify the root cause of an inadequate result of an unit.This can be achieved based on the application of several techniques presented in the figure. At first, the processing of the raw data (trends, laboratory data, balance sheets) is used to eliminate gross mistakes and misses. Next, at the identification stage, the processed sample is used to reveal the hidden structure of the object, i.e. determination of the main parameters that limit unit’s effectiveness. And based on the known criteria, laws and best practices, a physical interpretation of the statistical dependencies obtained is given, i.e. the cause of ineffective unit operation is determined.Further, a static and dynamic model of the process is developed that fully describes the current picture, and a solution that ensures the implementation of the stated goals.As a result, recommendations and solutions are stated.The advantages of this approach will be demonstrated by the example of the AT-9 Omsk Refinery.

Abstract:

The processes of thermal recovery (IAV, ICV, SAGD, among others) lead to aquatermolysis reactions occurring predominantly between 200 ° C and the range of 300-350 ° C, (Clark andHyne ,1984). In the present investigation the experimental simulations were carried out in reactors in lines with parameters of pressure and temperature of (750 Psi, 1200Psi, 200 ° C and 300 ° C) where the Voil:Vwater is 1: 2 and sands of (95.5% SiO2, 1.2% FeS2 and 3.3% clay minerals, these reactions were generated in gold tubes at time intervals of 1 to 21 days.The results obtained in the present investigation show a proportional relationship between the increase of the temperature and the time of reaction in the generation of H2S reaching concentrations of 3870 ppm related to 2.55 mL of H2S / g.oil sand, for the generation of CO2 as the reaction time increases decreasing the concentration until a minimum of 1.70 mL of CO2 / g.oil sand is reached, it is important to mention that at 200 ° C the concentrations of H2S are significantly lower (Maximum generation 0.13 mL of H2S / g.oil sand equivalent to 212 ppm H2S) compared to 300 ° C, which suggests possibly thermal cracking of organosulfur compounds identified (more 144 organosulfured compounds using a GCxGC TOF gas chromatograph) among them Dibenzothiophenes present in the aromatic fraction of the crude. However, the amount of H2S generated during the vaporization process is also correlated with the amount of polysulphides (R-Sx-R) thiophenes and Tiols (R-S-H) present.

Abstract:

Oil/gas are an old source of energy that have been used since its discovery, where the whole planet relies on. However, due to the environmental reasons and the development of the technology that people have recently discovered, they came to new inventions to produce new energy other than oil and gas, which called now the green energy or renewable energy.Green Energy is a source of energy that comes from natural sources such as sunlight or wind, apart from the wind mill there is another source of energy called the solar panel, it converts the sunlight to electricity usually it comprises the smaller units called photovoltaic cells to electricity. Scientists nowadays are trying to switch to green energy to reduce the hydrocarbon emissions that is produced from the natural gas, but they must consider a lot of transportations methods that still need oil in everyday life such as cars, airplane fuel or even gas central heating in winter. Some of the electric cars were used by people but to charge an electric car it need at least 30 min for the smallest battery where a atypical electric car it takes 4 hours to charge compared to the oil fuel where the car can move as soon as the tank is full in less than 5 min. The question is: Is green energy a thread to petroleum industry? No, green energy is still a new source of energy and it is under research, although the green energy is environmentally friendly, but it is not 100% relabel due to climate change, and still very expensive compared to oil and it is 100% reliable, as well as oil prices are very cheap where the bbl of oil reached its maximum price 2008 and was around $150 per bbl in 2008. Green energy is not 100% reliable for example wind mill or turbines stop spinning if the wind is not blowing fast enough or because of technical issues that cannot perform as it should be or due to a routine inspection or repairs, where there for the alternative is oil and gas which is 100% reliable source if the wind mill did stop completely. The solar system itself is very expensive it costs around £6000 just to install it. Oil and gas and its shipping worldwide to provide energy is actually a vital for our survival, companies may look at other resources such as solar or wind but for the meantime oil and gas is more economical efficient and quick. Industry is changing BP aims to invest more in renewables and clean energy but the world is going to need oil and gas for decades, hydrocarbons would remain the core of BP’s business, the company said it would start six new oil and gas projects this year.

Abstract:

Ethanol, due to its high octane rating of 108, is often added as adulterant to premium 91 gasoline fuels to boost up its octane rating to 96 or more but it does not provide the same power to engine as that of super-premium 96 gasoline fuels. In this study a novel sensitive Near Infra-Red (NIR) spectroscopy combined with multivariate is employed to detect and quantify ethanol adulteration in premium 91 gasoline fuels. Standard samples of premium 91 octane gasolines were collected from Oman Oil Refineries and Petroleum Industries Company (ORPIC). The premium 91 samples were then intentionally spiked with ethanol at various levels. NIR spectroscopy was employed for the analysis of all samples in the near-infrared region, absorption mode, in the range 700-2500 nm. Then the multivariate methods such as the Principal Component Analysis (PCA), the Partial Least Square Discriminant Analysis (PLSDA) and the Partial Least Square regression (PLS) analysis were used to interpret the obtained NIR spectral data. PLSDA model was developed to distinguish between the pure gasoline samples and those intentionally-adulterated by ethanol. For PLSDA model the obtained R-square value was 97% with 0.0769 RMSE. A PLS model was also developed to quantify the levels of ethanol adulterant in premium 91 gasoline samples. The obtained PLS regression model has an r-square value of 99% with 1.88 RMSECV values which is very close to the predicted RMSEP value i.e. 1.58 and R2 value of 99% for one factor loading.

Abstract:

During the hydrocarbon exploration activities, many challenges are faced in the ideal and accurate assessment of the oil reservoirs. Recently, there has been a practical revolution in estimating the reserves of unconventional reservoirs that were formerly useless. So far, there is no consensus on the exact definition of unconventional reservoirs in the Libyan oil industry, where the hydrocarbon is being produced from conventional reservoirs for ages. This study aims to help for better understanding and to clarify the confusion about the unconventional reservoirs, as well as analyze new opportunities to find new sources of energy and reserves in upper cretaceous (Santonian - Campanian) Tagrifet carbonate deposits across Waha block in the Hameimat Trough which is still virgin to explore for hydrocarbon, with no production tests ever made to recover from this section in the study area, it seems encouraging for further investigation and explore what behind this rocks. An integrated approach was used to evaluate the interesting zones using conventional and unconventional techniques to understand the key elements for the reservoir (Vsh, Sw, Phi and TOC) conducted on a variety of data including conventional well logs and wellbore data (gas surveys). Significant increasing in mud gas reading was observed in the wellbore gas surveys, in addition, oil shows are recognized using UV light indicate of oil staining and fluorescence, also stream-cut and crush-cut were examined. The reservoir characterized by the variation in reservoir property, the average porosity exceeds 10%, also the hydrocarbon saturation generally overrun the average of 50%. Notable correlation between the petrophysical results and the hydrocarbon show and downhole gas survey which further confirm the output of this study with good reservoir characteristics suitable for conventional and unconventional reservoirs.

Abstract:

The pre-upper cretaceous sandstone formation in Sirte Basin, Libya is considered as an important reservoir for hydrocarbon. The main traps system in A-Pool- NC98 block are structural and stratigraphic combination trapes, comprising of at least two major NW-SE trending tectonic blocks, each block is broken by a several more pre-upper-cretaceous faults. The present paper deals with evaluation of petrophysical for four exploration wells A3, A4, A5 and A6 and obtainable sedimentological integration with well A4 of upper Nubian sandstone reservoir occurs at a depth of between 14000-15500 feet, at A-Pool- NC98 block. Generally, the exploratory oil wells which drilled by Waha Oil Company in A-Pool, NC98 block, eastern Sirt Basin, Libya are producing from the upper Nubian sandstone reservoir. The upper Nubian sandstone reservoir is a complex of fine to medium grained, moderately to well cement mainly by silica and ferroan dolomite, grains are angular to rounded with straight, concave-convex and slightly sutured contacts. The geological and petrophysical evaluation have been done by using Techlog and Petrel software in study area taking a read every 0.5 feet and analyzed for detailed evaluation of reservoir parameters. The obtained petrophysical analysis are clearly showed that the upper Nubian sandstone considered as a good reservoir quality in wells A3, A4 and A5, whereas bad reservoir quality in well A6. The hydrocarbon in A-Pool is very rich retrograde condensate gas and waxy oil. The hydrocarbon has been sourced from hybrid petroleum systems (pre-upper cretaceous and upper cretaceous).Three main lithofacies have been recognized in upper Nubian sandstone by core interval; trough cross-bedded, horizontally laminated and low angle cross-bedded sandstones with many minor lithofacies such as rippled and fine laminated sandstones.

Abstract:

Enhanced Oil Recovery (EOR) is a generic term for techniques for increasing the amount of crude oil that can be extracted from an oil field. It is also called as improved oil recovery or tertiary recovery, sometimes the term quaternary recovery is used to refer to more advanced, speculative. Using EOR techniques 30 to 60% or more of the reservoir’s original oil can be extracted, compared with 20 to 40% using primary and secondary recovery. Thermal EOR is any process in which heat is introduced to reservoir in order to reduce the oil viscosity, mobility as well as the recovery factor. There are three thermal EOR projects in Sudanese oil fields namely two EOR projects in petro-energy company (Cyclic Steam Stimulation (CSS) in FNE oil field and Steam Flooding (SF) project in FNE oil field) and one (CSS) EOR project-bamboo west oil field thermal in Greater Nile Operating Company (GNPOC). The CSS projects are under implementation phase; meanwhile the steam flooding projects are under designing and preparation. In this paper there will be an overview of thermal EOR projects in Sudanese oil fields, the current status and way forward of this project as well as a main challenge for the different types of thermal EOR projects in various phases in Sudan. The results showed that the CSS projects are very successful and almost reward double production from 130 bbl/day to 300 bbl/day in FNE oil field and from 280 bbl/day to 471 bbl/day in bamboo oil field.

Abstract:

One of the clearest innovation and optimum documented transformation in Nigeria’s petroleum industry is the quick development of production capabilities in upstream sector since the discovery of crude oil in 1957. Over a decade, the four operational refineries with refining capacity of 445,000 Barrels Per Day (BPD) strategically situated across the nation is no longer functional. As a result, Nigeria still imports about 80% refined products, hence, tremendously reducing the global value chains in Nigeria’s petroleum industry. Nigeria petroleum industry is highly potent for ever increasing and sustainable global value chain, in that refining opportunity at her disposal. For instant, as at January 2017, Nigeria produces over 1.5 million bpd, as a result emerged as the 2^nd largest oil producer in Africa. From the refining product analysis, power and transportation driven by Premium Motor Spirit (PMS) consumes about 17 billion litres for Nigeria and 22 billion litres for West Africa Region (WAR) amounting to 90% and 70% importation of PMS spirit supplied annually for Nigeria and WAR respectively. Over 3 million litres and 11 million litres of Automotive Gas Oil (AGO) accounting to 60% importation of AGO consume in Nigeria and WAR annually as a result of erratic condition of power sector. It can observe that there is reserve opportunity and enormous potential uptake comparing the refinery production and consumption between Nigeria and WAR. If refined products are supplied by Nigeria refining sector, Nigeria will emerge as the West Africa’s refining hub soonest. However, in spite of the triggered transformation events fostered by the Government and petroleum industry in Nigeria so as to restore the nation’s refineries, until two novel considerations of investor’s guide are setup, Nigeria’s global value chain is not in view. Firstly, more modular refineries are needed to be built besides the four unproductive refineries and Dangote’s refinery under construction. Secondly, inculcating the principles employed by emerging economies and rising powers such as Brazil and China from production to innovation. The principles are enumerated but not limited to the following: (1) appealing for the return of Nigerian professional engineers, scientists and managers, (2) mobilizing financial institutions and government to buy novel technology and competent research teams and (3) indigenous establishment circumventing intellectual property right of exotic enterprises.

The Paper describes about converting ETP into a Future Power-House Hub of Refinery by generating Electricity from a combination of both Normal Steam Rankine Cycle and Organic Rankine Cycle in ETP.The Normal Steam Rankine Cycle will use High or Medium Pressure superheated steam produced by using all possible solid, liquid and gaseous fuels available in our Refinery, and from our nearby areas of NRL. These fuels are burnt in two different furnaces. The by-product from our future bio-refinery will also be used as a fuel. The combustion air required will be supplied from the ETP VOC blower itself, which is now vented (so loss converted into useful purposes) and some amount from Atmospheric air. The Flue gas produced on burning these various fuels will generate Super Heated High Pressure Steam (40 ksc/450 deg C) or Medium pressure steam (14.5 ksc/ 250 deg C) or MP of about 20.0 ksc/440+ deg C (more suitably MP of 20.0 ksc one). This steam will then drive the Condensing Steam Turbine Generator (or Back Pressure Turbine) and produce Electrical Power. The outlet steam is then condensed and sent back to the boiler. The cycle is repeated.

Organic Rankine Cycle:Here the organic compound with high molecular mass and lower boiling point than water will be used to recover heat from the lower temperature sources, like- flue gas heat coming out from the boiler at stack inlet. The working fluid is vaporized and then expanded in a vapor turbine that drives a generator, producing electricity. Here the working fluid may be silicon oil, isopentane, propane, etc. The Volatile Organic Compound (VOC) of ETP may also be used as a source of this fluid after further feasibility study of the composition and properties of the compound. We may recover VOC from different units of our Refinery which will act as a source of working fluid for this cycle. Also these VOCs can be used as a source of gaseous fuel in Furnace F2 and in different furnaces of Refinery.

Abstract:

There are several methods for production data analysis from shale gas reservoirs. In this study, nine different methods were used to analyze production data from 38 shale gas wells. The objective of this comparison study is to provide guidelines on which methods to use for production data analysis in shale gas wells. These nine methods include Arps’ (1945), Fetkovich (1980), Fraim and Wattenberger (1987), Modified Hyperbolic (1988), El-Banbi and Wattenbarger (1998), Power Law Decline (2008) and Bello and Wattenbarger (2009). The variations of these methods to cover homogeneous, pseudo-steady state dual porosity, constant pressure and constant rate closed reservoirs are all considered in the comparison. Production data from the 38 wells were categorized into 3 groups to cover the different conditions of observed rate and pressure variation. For every group of wells, half of the production history was history matched with all nine methods and the other half of production history was predicted. The deviation between predicted production forecast and actual production was used to shed light on the applicability of each method of the 9 for the 3 groups of wells. The results indicate that the best constant pressure methods for most of the wells are modified hyperbolic and power law decline with an average absolute error percent of 11% and 12.5%, respectively. In case of constant rate methods, the best method is found to be Bello and Wattenbarger with an average absolute error percent of 15.

Abstract:

Energy conservation has emerged as one of the major issues in recent years due to the increasing gap between the ever rising demand and the limited supply of energy. Improving our energy efficiency is the first and most important step towards narrowing down this gap. Energy is the main driving force of economic growth of a country. Tomorrow’s economic growth depends upon today’s efficient and effective use of energy. Hence, energy conservation and the practical application and creating awareness of energy efficient methods are very much essential for the sustenance and development of a modern economy of the country. Keeping in view the importance of the energy efficiency and conservation, following innovative schemes have been developed which are completely indigenous and in-house. The total monetary profit is 17.48 cores rupees per annum.
