Styrene Production from Methanol & Toluene - Cost Analysis - Styrene E41A


Book Description

This report presents a cost analysis of Styrene production from methanol and toluene. The process examined is similar to Exelus Styrene Monomer Technology (ExSyM). In this process, toluene undergoes an alkylation reaction with methanol to produce Styrene. Ethylbenzene is also generated as by-product. This report was developed based essentially on the following reference(s): Keywords: Styrene Monomer, Methanol, Toluene Alkylation, Exelus, ExSyM, SM

Styrene Production from Ethane & Benzene - Cost Analysis - Styrene E31A


Book Description

This report presents a cost analysis of Styrene production from ethane and benzene. The process examined is based on concepts proposed in patents issued to Dow and Snamprogetti. In this process, ethylbenzene (EB) is first generated from benzene feedstock and recycled ethylene. Then, fresh ethane and the EB are fed to a dehydrogenation reactor to simultaneously form ethylene, which is recycled, and Styrene as final product. Pure hydrogen is also generated as by-product. This report was developed based essentially on the following reference(s): Keywords: Styrene Monomer, SM, Ethylbenzene, Ethylene, Benzene, Alkylation, Dow, Snamprogetti

This report was developed based essentially on the following reference(s): Keywords: Styrene Monomer, SM, Ethylbenzene, CB&I Lummus, UOP, Classic SM, SMART SM, TOTAL, Badger




Styrene Production from Ethane & Benzene - Cost Analysis - Styrene E32A


Book Description

This report presents a cost analysis of Styrene production from ethane and benzene. The process examined was based on concepts proposed in patents issued to Dow and Snamprogetti. In this process, ethylbenzene (EB) is first generated from benzene raw material and recycled ethylene. Then, fresh ethane and the EB are fed to a dehydrogenation reactor to simultaneously form ethylene, which is recycled, and Styrene as final product. Hydrogen generated is valued as fuel. This report was developed based essentially on the following reference(s): Keywords: Styrene Monomer, SM, Ethylbenzene, Ethylene, Benzene, Alkylation, Dow, Snamprogetti




Styrene Production from Propylene & Ethylbenzene - Cost Analysis - Styrene E21A


Book Description

This report presents a cost analysis of Styrene production from chemical grade (CG) propylene and ethylbenzene. The process examined is a propylene oxide/styrene monomer (POSM) process similar to LyondellBasell technology. In this process, ethylbenzene is oxidized to produce ethylbenzene hydroperoxide, which reacts with propylene to produce Styrene and propylene oxide products. This report was developed based essentially on the following reference(s): "Propylene Oxide", Ullmann's Encyclopedia of Industrial Chemistry, 7th edition Keywords: Propene, Ethylbenzol, Oxidation, Epoxidation, EBHP, Phenylethene, POSM




Methanol Production from Natural Gas - Cost Analysis - Methanol E12A


Book Description

This report presents a cost analysis of large-scale Methanol production from natural gas. The process examined employs combined reforming for syngas generation similarly to the technologies developed by the following companies: Lurgi, Toyo, KBR, Johnson Matthey/Davy and Haldor-Topsoe. In this process, natural gas is converted into syngas in two steps: steam reforming and autothermal reforming. In the steam reformer, the natural gas reacts with steam and, in the secondary (autothermal) reformer, it reacts with oxygen. The syngas generated is then converted to Methanol. This report examines one-time costs associated with the construction of a United States-based plant and the continuing costs associated with the daily operation of such a plant. More specifically, it discusses: * Capital Investment, broken down by: - Total fixed capital required, divided in production unit (ISBL); infrastructure (OSBL) and contingency - Alternative perspective on the total fixed capital, divided in direct costs, indirect costs and contingency - Working capital and costs incurred during industrial plant commissioning and start-up * Production cost, broken down by: - Manufacturing variable costs (raw materials, utilities) - Manufacturing fixed costs (maintenance costs, operating charges, plant overhead, local taxes and insurance) - Depreciation and corporate overhead costs * Raw materials consumption, products generation and labor requirements * Process block flow diagram and description of industrial site installations (production unit and infrastructure) This report was developed based essentially on the following reference(s): (1) US Patent 8629190, issued to Lurgi in 2014; (2) US Patent 8388864, issued to Lurgi in 2013 Keywords: Synthesis Gas, Lurgi MegaMethanol, Johnson Matthey, JM Davy Technologies, Toyo, Kellogg Brown and Root, KBR, Johnson Matthey/Davy, Haldor-Topsoe




Styrene Butadiene Rubber Production - Cost Analysis - SBR E12A


Book Description

This report presents a cost analysis of Styrene Butadiene Rubber (SBR) production via solution process. The process examined is a typical continuous solution process. In this process the anionic copolymerization of styrene and butadiene is carried out continuously, in two cascade stirred tank reactors, in the presence of cyclohexane solvent. After reaction, the polymer solution is steam-stripped for the removal of solvent. The crumb slurry is then dried and sento to packaging section. This report was developed based essentially on the following reference(s): "Styrene-Butadiene Rubber", Kirk-Othmer Encyclopedia of Chemical Technology, 5th edition Keywords: Polymerization, Styrene Butadiene Rubber, sSBR, BD
