Paraxylene Production from Mixed Xylenes - Cost Analysis - Paraxylene E13A


Book Description

This report presents a cost analysis of para-Xylene production from mixed xylenes. The process examined is a xylene isomerization process with ethylbenzene (EB) dealkylation. In this process, a mixture of C8 aromatics containing xylene isomers and EB is sent to an adsorption unit for the recovery of p-Xylene. The p-Xylene-depleted stream is fed into the isomerization unit, where the remaining xylenes are isomerized to equilibrium and the EB is dealkylated to benzene by-product. This report was developed based essentially on the following reference(s): Keywords: Mixed Xylenes, C8 Aromatics, UOP, PAREX, Axens, Eluxyl, BP, AMSAC




Fundamentals of Petroleum Refining


Book Description

Fundamentals of Petroleum Refining presents the fundamentals of thermodynamics and kinetics, and it explains the scientific background essential for understanding refinery operations. The text also provides a detailed introduction to refinery engineering topics, ranging from the basic principles and unit operations to overall refinery economics. The book covers important topics, such as clean fuels, gasification, biofuels, and environmental impact of refining, which are not commonly discussed in most refinery textbooks. Throughout the source, problem sets and examples are given to help the reader practice and apply the fundamental principles of refining. Chapters 1-10 can be used as core materials for teaching undergraduate courses. The first two chapters present an introduction to the petroleum refining industry and then focus on feedstocks and products. Thermophysical properties of crude oils and petroleum fractions, including processes of atmospheric and vacuum distillations, are discussed in Chapters 3 and 4. Conversion processes, product blending, and alkylation are covered in chapters 5-10. The remaining chapters discuss hydrogen production, clean fuel production, refining economics and safety, acid gas treatment and removal, and methods for environmental and effluent treatments. This source can serve both professionals and students (on undergraduate and graduate levels) of Chemical and Petroleum Engineering, Chemistry, and Chemical Technology. Beginners in the engineering field, specifically in the oil and gas industry, may also find this book invaluable. - Provides balanced coverage of fundamental and operational topics - Includes spreadsheets and process simulators for showing trends and simulation case studies - Relates processing to planning and management to give an integrated picture of refining




Benzene Production from Pygas - Cost Analysis - Benzene E12A


Book Description

This report presents a cost analysis of Benzene production from pyrolysis gasoline (pygas). The process examined is a typical hydrodealkylation process, also called bulk dealkylation process. First pygas is fractionated into 3 hydrocarbon cuts, a C5s stream and a heavies stream are generated as by-products. The remaining C6-C8 fraction is then directed to the hydrodealkylation step, in which the aromatics content in the process stream are converted into benzene This report was developed based essentially on the following reference(s): "Benzene", Ullmann's Encyclopedia of Industrial Chemistry, 7th edition Keywords: Aromatics, BTX, Diprolene, Toluene, Xylene, Houdry Pyrotol, Mitsubishi MHC, Bulk Dealkylation, CB&I Lummus

The Chemistry of Polymers


Book Description

The scientific field that is concerned with the chemical synthesis, structure, and the physical and chemical properties of polymers and macromolecules is known as polymer chemistry. Its principles and methods are also applicable in a variety of sub-disciplines of chemistry such as organic chemistry, physical chemistry and analytical chemistry. On the basis of their origin, polymers are subdivided into biopolymers and synthetic polymers. The functional and structural materials that make most of the organic matter in organisms are biopolymers. Synthetic polymers are the structural materials that are manifested in synthetic fibers, paints, building materials, furniture, plastics, mechanical parts and adhesives. This book is a compilation of chapters that discuss the most vital concepts in the field of polymer chemistry. Some of the diverse topics covered herein address the varied branches that fall under this category. Those in search of information to further their knowledge will be greatly assisted by this book.
