Abstract
Steam carrying fatty acids is contacted in a barometric condenser with a cooling medium comprising a fatty acid having between six and eighteen carbon atoms to produce a liquid organic phase containing the fatty acids which were entrained in the steam, and an aqueous phase, such phases being readily separated by decantation. After separation of the phases, a portion of the organic phase is used for the cooling medium.
Claims6
The process of separating fatty acids from steam containing fatty acids entrained therein, comprising contacting the steam and fatty acids therein with a cooling medium comprising a fatty acid having between six and eighteen carbon atoms which is miscible with the fatty acids entrained in the steam passed directly to a barometric condenser to form a condensate of acid vapors, said cooling medium having a temperature above about 80.degree. F., separating the resulting organic and water phases of the condensate by decantation, recycling a portion of the organic phase for use as the cooling medium, and processing the other separated liquid components for recovery of water and fatty acids.
