RECOVERY OF MULTIPLE COMPOUNDS AND RECYCLABLE WATER FROM THIN STILLAGE

摘要

Methods for recovery of recyclable water and/or fermentation co-products from thin stillage process streams. Microbial metabolites and/or plant derivatives and/or plant extractives are removed from thin stillage after which, recyclable water is recovered from the processed thin stillage. Thin stillage is commingled with one or more polar organic solvents to react microbial metabolites and/or plant derivatives and/or plant extractives with the organic solvents. The reacted organic solvents are then separated from the processed thin stillage. Thin stillage may be commingled with an oil to react with certain organic compounds, after which, the reacted oil is separated from the processed thin stillage is further extracted with one or more polar organic solvents. Alternatively, thin stillage may be first processed with one or more polar organic solvents, and then processed with an oil. Useful organic compounds may recovered from the reacted oil and from the reacted organic solvents.
