Membranes on Polyolefins Plants Vent Recovery
Gas separation by membranes has acquired increasing importance in the petrochemical industry and is now a relatively well-established unit operation, especially in the monomer recovery of polymer production processes. Considering the current tight monomers market, polymer degassing steps present potential improvement opportunities, through the recovery of vent streams containing monomers. The economic analysis presented in this report is based upon the installation of a membrane-based propylene recovery unit in a polypropylene plant, a unit similar to MTR VaporSep(r). Such measure was demonstrated to be attractive in the US Gulf Coast, due to propylene scarcity, which has recently raised its...
Biodiesel Production from Soybean Oil - Cost Analysis - Biodiesel E13A
This report presents a cost analysis of Biodiesel production from soybean oil using a heterogeneous catalysis process. The process examined is similar to Axens Esterfip-H process. In this process, crude glycerol is generated as by-product. This report was developed based essentially on the following reference(s): (1) US Patent 7151187, issued to Institut Français du Pétrole (IFP) in 2006 (2) US Patent 9029583, issued to Council of Scientific & Industrial Research in 2015 Keywords: Fatty Acid Methyl Ester, FAME, Glycerin, Transesterification, Solid Catalyst, Refined Vegetable Oil
Ethylene Production via Ethanol Dehydration - Cost Analysis - Ethylene E83A
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
Butanol Production from Propylene and Syngas - Cost Analysis - Butanol E71A
This report presents a cost analysis of n-Butanol production from propylene and syngas. The process examined is similar to the technology jointly developed by Rhodia (former Rhône-Poulenc) and Ruhrchemie. This process relies on a water-soluble rhodium catalyst for the hydroformylation of propylene to form n-butyraldehyde and isobutyraldehyde. The isobutyraldehyde is separated as a by-product and the n-butyraldehyde is hydrogenated to form n-Butanol as the final product. This report was developed based essentially on the following reference(s): Keywords: Oxo Alcohol, Butyl Alcohol, n-Butanol, Rhodia, Rhône-Poulenc, Ruhrchemie
Butyraldehyde Production from Propylene and Syngas - Cost Analysis - Butyraldehyde E21A
This report presents a cost analysis of n-Butyraldehyde production from propylene and syngas. The process examined is similar to the LP OXO technology jointly developed by JM Davy and Union Carbide, employing Selector 10 catalyst. In this process, the production ratio of n- to iso-butyraldehyde in the oxo reaction is about 10. The n-Butyraldehyde is separated as the final product and the isobutyraldehyde is obtained as a by-product. This report was developed based essentially on the following reference(s): Keywords: Oxo Synthesis, Butanal, Synthesis Gas, H2, CO, Hydrogen, Carbon Monoxide, Johnson Matthey, Dow, LP Oxo, SELECTOR
Acetic Acid Production from Ethane - Cost Analysis - Acetic Acid E31A
This report presents a cost analysis of Acetic Acid production from ethane. In this process, ethane is oxidized forming Acetic Acid. This report was developed based essentially on the following reference(s): Keywords: Ethane Direct Oxidation, EDO, SABIC, Saudi Arabia Basic Industries Corporation
Tanespimycin Production from Corn - Cost Analysis - Tanespimycin E11A
This report presents a cost analysis of Tanespimycin production from corn. The process examined is a typical fermentation process. In this process, geldanamycin intermediate is produced from fermentation. Then, geldanamycin is purified and converted to Tanespimycin. This report was developed based essentially on the following reference(s): Keywords: Pharmacia & Upjohn Company, Pfizer, Conforma Therapeutics Corporation, Antitumor Antibiotic, Hsp90 Inhibitor, Heat Shock Protein 90, Cancer Treatment
Low Solids Styrene Butadiene Latex Production - Cost Analysis - SBR E31A
This report presents a cost analysis of Low Solids Styrene Butadiene Latex production via cold emulsion polymerization process. The process examined is a typical continuous cold emulsion process for producing a low solids, non-carboxylated grade of SBR Latex with high styrene content. In this process, an emulsion, comprising water, styrene and butadiene monomers, is polymerized into a very low solids latex, which passes through a concentration step for generating a low solids latex. This report was developed based essentially on the following reference(s): Keywords: Polymerization, Styrene Butadiene Latex, SB Latex
Acrylonitrile Butadiene Latex Production - Cost Analysis - NBR E21A
This report presents a cost analysis of NBR Latex production from acrylonitrile and butadiene. The process examined is a typical cold emulsion polymerization process. In this process, acrylonitrile and butadiene are copolymerized into low solids content NBR Latex. This report was developed based essentially on the following reference(s): Keywords: Synthetic Latex, Nitrile Elastomer, Nitrile Butadiene Latex, NBR Latex, Acrylonitrile Butadiene Copolymer Latex, Nipol, Krynac, Europrene
Phenol Production from Benzene and Propylene - Cost Analysis - Phenol E41A
This report presents a cost analysis of Phenol production from benzene and chemical grade (CG) propylene. The process examined is a typical hydroperoxidation process. In this process, benzene and propylene are used to produce cumene, which is then converted to Phenol. Acetone is generated as by-product. This report was developed based essentially on the following reference(s): Keywords: Isopropylbenzene, Carbolic Acid, Cumene Hydroperoxide
