Title:
RECOVERY PROCESS FOR VOLATILE COMPOUNDS FROM SOLIDS IN AQUEOUS SOLUTION
Document Type and Number:
WIPO Patent Application WO2001023061
Kind Code:
A3
Abstract:
Volatile compounds may be economically recovered from solids present in aqueous solution by subjecting the solution to rapid separation where the volatilization occurs in a flash, spray, or fluid bed, or mechanically agitated dryers. Rapidly separating the solids from the volatile compound greatly simplifies the isolation of the volatile compounds from water. The methods have utility for fermentation processes, solids management, and recycling processes.
