Publication number: 20080103335Abstract: An improvement of the methanol carbonylation process for manufacturing acetic acid is disclosed. Specifically disclosed is a method for reducing the formation of alkyl iodides and C3-8 carboxylic acids by removing permanganate reducing compounds (“PRC's”) from the light phase of the condensed light ends overhead stream, including (a) distilling the light phase to yield a PRC enriched overhead stream; and (b) extracting the third overhead stream with water in at least two consecutive stages and separating therefrom one or more aqueous streams containing PRC”s.Type: ApplicationFiled: April 20, 2007Publication date: May 1, 2008Inventors: Mark Scates, David Trueba, Raymond Zinobile

Publication number: 20070197822Abstract: The present invention is directed to using methyl acetate from a vinyl acetate-based or a vinyl-or ethylene-alcohol based polymer or copolymer process directly for use in a methanol carbonylation production process to produce acetic acid, acetic anhydride, or a coproduction of each. Methyl acetate is a by-product of commercial polyvinyl-alcohol or alkene vinyl alcohol copolymer-based processes. Generally, this material is processed to recover methanol and acetic acid. Discussed herein is a cost-saving scheme to by-pass the methyl acetate processing at production or plant facilities and utilize the methyl acetate in an integrated methanol carbonylation unit. The scheme discussed eliminates an expensive hydrolysis step often associated with the polymer process.Type: ApplicationFiled: November 22, 2006Publication date: August 23, 2007Inventors: Wayne Picard, Mark Scates, Stephen Webb, Duane Usrey
