  • HIGH TEMPERATURE ESTER HYDROLYSIS OPERATING AT HIGH ESTER TO WATER RATIOS
    Publication number: 20150080615
    Abstract: A process for recovering alcohol from a fatty acid and/or diacid alcohol ester using water in an equal or lesser amount than oil on a mass basis. The process uses multiple reactors with separation of the alcohol product of hydrolysis between successive reactors. The use of low amounts of water allows recovery of the alcohol with a lower evaporation requirement, thus making a more energy efficient process.
