Book Description
This report presents a cost analysis of polymer grade (PG) Ethylene production from hydrous ethanol using a dehydration process. The process under analysis is similar to the process developed by Scientific Design. In this process ethanol is dehydrated in the vapor phase to Ethylene in a system comprised of 1 reactor and 1 furnace. The product from reaction is passed through quench, compression and distillation, so Polymer Grade Ethylene can be obtained. This report was developed based essentially on the following reference(s): Bruscino, M., 'Biorefineries: Fact or Fiction?', Hydrocarbon Processing, August 2009, Vol. 88 No. 8 p.65-70 Keywords: Ethene, Ethyl Alcohol, SD, Syndol Catalyst, Vapor-Phase Dehydration, Fixed-Bed Reactor, Renewable Feedstock, Green Ethylene

Book Description
This comprehensive review, prepared by 24 experts, many of whom are pioneers of the subject, brings together in one place over 40 years of research in this unique publication. This book will assist R & D specialists, research chemists, chemical engineers or process managers harnessing periodic operations to improve their process plant performance. Periodic Operation of Reactors covers process fundamentals, research equipment and methods and provides "the state of the art" for the periodic operation of many industrially important catalytic reactions. Emphasis is on experimental results, modeling and simulation. Combined reaction and separation are dealt with, including simulated moving bed chromatographic, pressure and temperature swing and circulating bed reactors. Thus, Periodic Operation of Reactors offers readers a single comprehensive source for the broad and diverse new subject. This exciting new publication is a "must have" for any professional working in chemical process research and development. - A comprehensive reference on the fundamentals, development and applications of periodic operation - Contributors and editors include the pioneers of the subject as well as the leading researchers in the field - Covers both fundamentals and the state of the art for each operation scenario, and brings all types of periodic operation together in a single volume - Discussion is focused on experimental results rather than theoretical ones; provides a rich source of experimental data, plus process models - Accompanying website with modelling data

Book Description
This report presents a cost analysis of polymer grade (PG) Ethylene production from hydrous ethanol using a dehydration process. The process under analysis is similar to the processes developed by Braskem and Petrobras. In this process, the reaction system is composed of multiple reactors and multiple furnaces. Before feeds each reactor, steam is mixed with ethanol as diluent to avoid an excessive temperature drop as dehydration reaction proceeds. This report was developed based essentially on the following reference(s): Keywords: Ethene, Ethyl Alcohol, Vapor-Phase Dehydration, Fixed-Bed Reactor, Renewable Feedstock, Green Ethylene

Book Description
The primary goals of this research were to develop an efficient standard operating procedure for undergraduate students and researchers performing reactions within a packed bed reactor and to determine the optimal operating conditions for phenethylamine formation from mandelonitrile hydrogenation. With the current laboratory packed bed reactor system, undergraduates can conduct gas-liquid phase reactions at a maximum temperature of 95°C and a maximum pressure of 100 psi. The versatile system setup can be modified for unit operations laboratory instruction or future researchers analyzing heterogeneous catalysis reactions. The developed standard operating procedure provides detailed instructions on packing the reactor with a solid catalyst, activating the catalyst, operating the high-pressure liquid syringe pump, reaction moderating, and sample collection. Primary amines serve as a versatile intermediate in a range of industrial processes. As a result of their importance, many synthesis methods are used to form the desired compound. Hydrogenation of a nitrile is one of the common reaction pathways to produce a high concentration of a given primary amine. The process outlined in this paper demonstrates a method for the synthesis of phenethylamine, a primary amine, from the hydrogenation of mandelonitrile using a carbon-supported palladium catalyst. Reactant conversion and weighted hourly space velocity analysis were performed to determine the optimal operating conditions. Reactor feed flow rates of 0.1, 0.2, 0.25, 0.3, 0.35, 0.375, and 0.4 mL/min and temperatures of 40°C and 70°C were studied. The formation of phenethylamine was confirmed using High-Performance Liquid Chromatography, with the highest conversions of mandelonitrile observed at flow rates of 0.2 and 0.3 mL/min.
