  • Method and apparatus for making acetic acid with improved light ends column productivity
    Patent number: 8173076
    Abstract: An improved apparatus and method of producing acetic acid includes condensing overhead vapor to provide reflux to the light ends column as well as condensing vapor from a central portion of the light ends column to increase capacity. Throughput or load on the light ends column is substantially reduced without compromising product quality.

  • PROCESS FOR PRODUCING ETHANOL USING AN EXTRACTIVE DISTILLATION COLUMN
    Publication number: 20110275864
    Abstract: Recovery of ethanol from a crude ethanol product obtained from the hydrogenation of acetic acid. Separation and purification processes of crude ethanol product are employed to allow recovery of ethanol and remove impurities. In addition, the process involves separating the crude ethanol product using an extractive distillation column that employs an extraction agent, such as a recycled stream comprising water.

  • Process for Heat Integration for Ethanol Production and Purification Process
    Publication number: 20110190552
    Abstract: Ethanol production from the hydrogenation of acetic acid requires energy to drive the hydrogenation reaction and the purification of the crude ethanol product. Heat integration process to recover heat from one part of the production process to be used within the process improves efficiencies and reduces costs.

  • Method and apparatus for making acetic acid with improved purification
    Patent number: 7619113
    Abstract: An improved method of producing acetic acid includes condensing overhead vapor from a light ends column and decanting the condensed vapor to a light phase and a heavy phase. The heavy phase consists predominantly of methyl iodide and at least a portion of the decanted heavy phase is refluxed to the light ends column. Acetic acid content of the light ends column overhead stream and water content of the light ends column product (sidedraw) stream are both decreased, improving purification efficiency.
