Butyl Acrylate Production from Propylene and Butanol - Cost Analysis - Butyl Acrylate E21A

This report presents a cost analysis of n-Butyl Acrylate production from chemical grade propylene and n-butanol. The process examined is a typical propylene oxidation, followed by a typical esterification process. 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...

This report presents a cost analysis of n-Butyl Acrylate production from chemical grade propylene and n-butanol. The process examined is a typical propylene oxidation, followed by a typical esterification process. 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 to be combined with n-butanol in a esterification reactor to generate crude a crude ester stream that is furhter purified to generate high-purity butyl acrylate.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) ""Acrylic Acid"", Ullmann's Encyclopedia of Industrial Chemistry, 7th edition; (2) ""Acrylic Acid and Derivatives"", Kirk-Othmer Encyclopedia of Chemical Technology, 5th editionKeywords: Propene, Air Oxidation, Propenoic Acid, Nippon Shokubai, Rohm & Haas, Dow, Esterification, Nippon Shokubai, Mitsubishi, BASF
