20100294642 | OLEFIN PRODUCTION FROM SYNGAS BY AN INTEGRATED BIOLOGICAL CONVERSION PROCESS - The production of feed for an olefin hydration zone is improved by integrating treatment of an alcohol containing stream from a fermentation zone into an alcohol separation section. The process passes a stream comprising alcohol, water and an organic acid to a separation column. The separation column concetrates the alcohol and organic acids into an upper column fraction. An additive for neutralization the organic acid into contact with said upper column fraction and reacts with the organic acid to produce a neutralization product that passes to a lower portion of the separation column. The column provides an overhead stream for an olefin dehydration zone having an increased concentration of alcohol and a reduced concentration of organic acid. A column bottoms stream containing the neutralization product returns as an input stream to supply the neutralization product to a fermentation zone that produces the alcohol containing stream. | 11-25-2010 |
