Title: RECOVERY OF ISOPRENE FROM FERMENTATION PROCESSES USING MECHANICAL COMPRESSION AND CONDENSATION
Abstract:
The present invention discloses methods of recovering isoprene from a feed stream consisting of isoprene, water, ethanol, and lower boiling compounds. The isoprene- containing feed stream is compressed in a manner to avoid excessive heat while condensing a portion of the water contained in the feed stream, the vapor stream is further dried, and isoprene is condensed there form thus separating the isoprene from a substantial portion of the lower boiling compounds, and collecting the isoprene.
