Source Assessment Acrylic Acid Manufacture

This report presents a cost analysis of Ester-Grade Acrylic Acid (EAA) production from chemical grade (CG) propylene The process examined is a typical propylene oxidation. In this process, propylene passes through a two-stage vapor phase oxidation to generate an acrylic acid-containing gas, from which acrylic acid is recovered via absorption in water. The aqueous acrylic acid solution is purified via light solvent extraction to Ester-grade Acrylic Acid (EAA), which is used in the production of acrylic esters. This report was developed based essentially on the following reference(s): "Acrylic Acid", Ullmann's Encyclopedia of Industrial Chemistry, 7th edition Keywords: Propene, Air Oxidation, Propenoic Acid, Nippon Shokubai, Rohm & Haas, Dow

This report presents a cost analysis of Ester-Grade Acrylic Acid (EAA) production from propane The process examined is a novel process for propane oxidation. In this process, propane is fed to an oxydehydrogenation reactor in the presence of steam to form propylene. The propylene-containing gas passes through a two-stage vapor phase oxidation to generate an acrylic acid-containing gas, from which acrylic acid is recovered via absorption in water. The aqueous acrylic acid solution is purified via light solvent extraction to Ester-grade Acrylic Acid (EAA). This report was developed based essentially on the following reference(s): (1) "Acrylic Acid and Derivatives", Kirk-Othmer Encyclopedia of Chemical Technology, 5th edition (2) US Patent 6492548, issued to Union Carbide in 2002 Keywords: Propene, Air Oxidation, Propenoic Acid, Nippon Shokubai, Rohm & Haas, Dow
