Propylene Oxide from Propylene and Isobutane - Cost Analysis - Propylene Oxide E23A


Book Description

This report presents a cost analysis of Propylene Oxide (PO) production from chemical grade (CG) propylene and isobutane. The process examined is similar to LyondellBasell process. In this process, isobutane is oxidized to produce t-butyl hydroperoxide, which reacts with propylene to produce Propylene Oxide. t-Butanol is generated as by-product in the process. This report was developed based essentially on the following reference(s): (1) US Patent 5196597, issued to Arco Chemical Technology in 1993 (2) US Patent 3849451, issued to Halcon International in 1974 Keywords: Propene, Methylpropane, Oxidation, Epoxidation, TBHP, tert-Butyl Alcohol, TBA, PO/TBA




Design and Analysis of Heat Sinks


Book Description

A powerful methodology for producing superior thermal performance at low cost with minimum added mass . . . Here is the only available comprehensive treatment of the design and analysis of heat sinks. It provides all the theoretical and practical information necessary to successfully design and/or select cost-effective heat sinks for electronic equipment. The presentation includes detailed explanations of the governing heat transfer phenomena, complete coverage of thermal modeling tools for geometrically complex fin structures, and extensive discussion on recognizing thermal optimization opportunities. Other topics covered include: Fundamentals of heat transfer Thermal modeling of electronic packages Mathematical tools for heat-sink analysis and design Prevailing thermal transport processes Models for a variety of fin geometries Simple "transfer function" relations for single fin, cascaded fin, and fin array heat sinks Thermal characterization and optimization of plate-fin heat sinks Completely self-contained and filled with valuable information not available from any other single source, Design and Analysis of Heat Sinks is both a superior reference for accomplished thermal specialists and an excellent textbook for graduate courses in advanced thermal applications for mechanical engineering students. This book can also serve as a text in thermal science for students of electrical engineering.




Analytical Methods in Conduction Heat Transfer


Book Description

This book is designed for a one-semester graduate course in conduction heat transfer. The three major chapters are: 3 (separation of variables), 8 (finite differences) and 9 (finite elements). Other topics include Bessel functions, Laplace transforms, complex combination, normalization, superposition and Duhamel's theorem.




Direct-Contact Heat Transfer


Book Description

to increase the use of direct contact processes, the National Science Foundation sup ported a workshop on direct contact heat transfer at the Solar Energy Research Insti tute in the summer of 1985. We served as organizers for this workshop, which em phasized an area of thermal engineering that, in our opinion, has great promise for the future, but has not yet reached the point of wide-spread commercial application. Hence, a summary of the state of knowledge at this point is timely. The workshop had a dual objective: 1. To summarize the current state of knowledge in such a form that industrial practi tioners can make use of the available information. 2. To indicate the research and development needed to advance the state-of-the-art, indicating not only what kind of research is needed, but also the industrial poten tial that could be realized if the information to be obtained through the proposed research activities were available.




Ethylene Production Cost Analysis - Overview - Ethylene AA01


Book Description

This report presents alternatives for producing Ethylene from different feedstocks and a cost comparison of these alternatives, across different countries. More specifically, the report compares the costs of Ethylene production through the following pathways: * Pathway 1: Ethylene Production from Ethane * Pathway 2: Ethylene Production from Ethane and Propane * Pathway 3: Green Ethylene Production from Ethanol In Pathways 1 and 2, Ethylene is produced via steam cracking of different feedstocks: ethane and a mixture of ethane and propane. In Pathway 3, Ethylene is produced from ethanol, which is a renewable feedstock. The analysis presented in this report includes: * A comparison of the economic potential of the pathways listed above in several countries, comprising: - Comparative analysis of capital costs - Comparative analysis of production costs - Comparison between product price and raw materials costs of each pathway * An overview of each production pathway, including: - Raw material(s) consumption figures and product(s) generated - Related technology licensors and block flow diagram of representative industrial processes Keywords: Hydrocarbon Pyrolysis, Cracking Furnace, Ethene, Propene, Shale Gas, CB&I Lummus, Technip, Shaw Stone & Webster, Kellogg-Braun & Root, KBR, Linde, Green Ethylene, Braskem, Chematur Technologies, Petron Scientech, Scientific Design, Dow Chemical, BP, Ethanol Dehydration




Ethylene Production via Steam Cracking of Isobutane - Cost Analysis - Ethylene E51A


Book Description

This report presents a cost analysis of polymer grade (PG) Ethylene production from isobutane feedstock using a typical steam cracking process In this process, isobutane is thermally cracked in pyrolysis furnaces through the use of steam. In addition to Ethylene, the process also generates polymer grade propylene, butadiene , raffinate-1 and pygas as by-products. This report was developed based essentially on the following reference(s): "Ethylene", Ullmann's Encyclopedia of Industrial Chemistry, 7th edition Keywords: Ethene, Propene, Pyrolysis Gasoline, Hydrocarbon Pyrolysis, Cracking Furnace, Lummus, KBR, Technip, Linde, S&W
