Available in PDF, EPUB and Kindle. Book excerpt: Gasification of petroleum coke (Petcoke) has emerged in the last decades as one of the attractive options and is gaining more attention to convert petcoke and oil residue to synthesis gas (Syngas). Syngas consists mainly of hydrogen (H2), carbon monoxide (CO), some other gases, and impurities. In this study, a simulation of Tuscaloosa petcoke, typical gulf coast refineries petcoke, gasification was developed using ASPEN PLUS software. Sensitivity analysis of the simulated model was performed to study the variation in operation conditions of the gasifier such as temperature, pressure, oxygen flow rate, and steam flow rate. The approach correlates the behavior of these parameters with the syngas yield (i.e., H2, CO, CO2, H2O, CH 4, and H2S). Consequently, the desired syngas yield can be obtained by manipulating the gasifier parameters. Implementing optimization calculation shows that up to (81 %) of the gasifier cold gas efficiency (Based on LHV) can be achieved for the developed model. Therefore, Tuscaloosa petcoke gasification under the aforementioned parameters is feasible and can be commercialized. This leads to more utilization of the bottom of oil barrel by upgrading it to more valuable gases with less environmental impacts.

Download or read book Analysis of Power Generation Processes Using Petcoke written by Ramkumar Jayakumar and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Petroleum coke or petcoke, a refinery byproduct, has generally been considered as an unusable byproduct because of its high sulfur content. However energy industries now view petcoke as a potential feedstock for power generation because it has higher carbon content than other hydrocarbons like coal, biomass and sewage residue. This gives petcoke a great edge over other feedstocks to generate power. Models for the two most common processes for power generation, namely combustion and gasification, were developed using Aspen Plus steady state chemical process simulator. Overall plant layouts for both processes were developed by calculating the heat and mass balance of the unit operations. After conducting wide sensitivity analysis, results indicate that one ton of petcoke feedstock can generate up to 4 MW of net available power. Both processes have rates of return greater than 30%, although gasification offers a slightly more attractive opportunity than combustion.

This book was released on 2011-02-14 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the current carbonaceous fuel conversion technologies based on chemical looping concepts in the context of traditional or conventional technologies. The key features of the chemical looping processes, their ability to generate a sequestration-ready CO2 stream, are thoroughly discussed. Chapter 2 is devoted entirely to the performance of particles in chemical looping technology and covers the subjects of solid particle design, synthesis, properties, and reactive characteristics. The looping processes can be applied for combustion and/or gasification of carbon-based material such as coal, natural gas, petroleum coke, and biomass directly or indirectly for steam, syngas, hydrogen, chemicals, electricity, and liquid fuels production. Details of the energy conversion efficiency and the economics of these looping processes for combustion and gasification applications in contrast to those of the conventional processes are given in Chapters 3, 4, and 5.Finally, Chapter 6 presents additional chemical looping applications that are potentially beneficial, including those for H2 storage and onboard H2 production, CO2 capture in combustion flue gas, power generation using fuel cell, steam-methane reforming, tar sand digestion, and chemicals and liquid fuel production. A CD is appended to this book that contains the chemical looping simulation files and the simulation results based on the ASPEN Plus software for such reactors as gasifier, reducer, oxidizer and combustor, and for such processes as conventional gasification processes, Syngas Chemical Looping Process, Calcium Looping Process, and Carbonation-Calcination Reaction (CCR) Process.

Download or read book Simulation and Techno economic Analysis of Pressurized Oxy fuel Combustion of Petroleum Coke written by Hachem Hamadeh and published by . This book was released on 2018 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: The research presented in this thesis was part of the International Partnership for Carbon Neutral Combustion, which was sponsored by King Abdulla University of Science and Technology. The thesis focuses on oxy-fuel combustion under pressurized conditions and assesses the technical and economic viability of combusting petroleum coke (petcoke) for electricity generation, while capturing CO2. The technical evaluation was conducted through simulating, in Aspen PlusTM, an oxy-combustion power plant that uses petcoke as fuel. The basis for all simulations was a constant heat input of 1877 MWth, while a 3% (on dry basis) excess oxygen was maintain in the flue gas along with an adiabatic flame-temperature of 1866ʻC. Comparisons with the oxy-combustion of Illinois No. 6 coal showed that oxy-coal combustion was 0.6% points (on HHV basis) more efficient than oxy-petcoke combustion (29.0% versus 29.6%). However, operating oxy-petcoke combustion at elevated pressures improved the net efficiency to a maximum of just over 29.8% (on HHV basis) at 10 bar. A sensitivity analysis on the impact of operating pressure was conducted on the fuel intake, O2 required, recycle ratio and removal ratio of SOx and NOx via flash distillation; along with how the operating pressure within the carbon capture unit affects the recovery and purity of the CO2 being separated. The sensitivity analysis showed that pressure had minimal impact on the fuel intake and O2 required but affected recycle ratio by up to 3% points, while increasing pressure improved the removal ratio of SOx and NOx. As for the operating pressure of the carbon capture unit, the recovery and purity of the CO2 produced was preferred at 35 bar. In addition, a modification to the steam cycle is presented that utilizes the latent heat of the flue gas to heat the feed water, which improves the net efficiency of the power plant at all pressures by 1.9% points. As for the economic evaluation, the oxy-petcoke combustion power plant was assumed to be built in the US and in KSA. The levelized cost of electricity (LCOE) for oxy-coal combustion was 11.6 [cent]/kWh (in 2017 USD) compared to 10.4 [cent]/kWh and 6.5 [cent]/kWh for atmospheric oxy-petcoke combustion in the US and in KSA, respectively. The LCOE further drops to a minimum of 9.2 [cent]/kWh in the US, or 5.7[cent]/kWh in KSA, when oxy-petcoke combustion takes place at 10 or 15 bar. However, based on a profitability analysis, operating at 10 bar has the highest net profit, highest net present value and lowest discounted payback period, compared to the plants operating at 1, 5 and 15 bar, whether in the US or in KSA. A sensitivity analysis was also conducted that showed that the cost of manufacturing (COM), LCOE and costs of CO2 avoided and CO2 capture are most sensitive to total capital cost, and to a lesser extent the cost of the fuel, which in this case is petcoke. Overall, the technical and economic evaluation help conclude that using petcoke as a fuel to generate electricity is viable in oil-refining countries like the US or KSA, in which pressurized oxy-petcoke combustion is better than atmospheric as the highest net efficiency and lowest LCOE are achieved at an operating pressure of 10 bar.

Available in PDF, EPUB and Kindle. Book excerpt: Skyrocketing energy costs have spurred renewed interest in coal gasification. Currently available information on this subject needs to be updated, however, and focused on specific coals and end products. For example, carbon capture and sequestration, previously given little attention, now has a prominent role in coal conversion processes.This book approaches coal gasification and related technologies from a process engineering point of view, with topics chosen to aid the process engineer who is interested in a complete, coal-to-products system. It provides a perspective for engineers and scientists who analyze and improve components of coal conversion processes.The first topic describes the nature and availability of coal. Next, the fundamentals of gasification are described, followed by a description of gasification technologies and gas cleaning processes. The conversion of syngas to electricity, fuels and chemicals is then discussed. Finally, process economics are covered. Emphasis is given to the selection of gasification technology based on the type of coal fed to the gasifier and desired end product: E.g., lower temperature gasifiers produce substantial quantities of methane, which is undesirable in an ammonia synthesis feed. This book also reviews gasification kinetics which is informed by recent papers and process design studies by the US Department of Energy and other groups, and also largely ignored by other gasification books.• Approaches coal gasification and related technologies from a process engineering point of view, providing a perspective for engineers and scientists who analyze and improve components of coal conversion processes • Describes the fundamentals of gasification, gasification technologies, and gas cleaning processes • Emphasizes the importance of the coal types fed to the gasifier and desired end products • Covers gasification kinetics, which was largely ignored by other gasification books - Provides a perspective for engineers and scientists who analyze and improve components of the coal conversion processes - Describes the fundamentals of gasification, gasification technologies, and gas cleaning processes - Covers gasification kinetics, which was largely ignored by other gasification books
