Abstract

A liquid feed stock containing oil is deodorized in a semicontinuous process wherein the feed stock, in a first evacuated chamber, undergoes heat exchange with a deodorized stock in a second evacuated chamber, said stocks being circulated in their respective chambers by upwardly flowing steam introduced into each chamber between a partition, separating the two chambers, and a guide plate parallel to said partition and spaced therefrom, whereafter said feed stock is passed through a succession of steam heating stages to heat said feed stock to successively higher temperatures thereby deodorizing the feed stock and then withdrawn as deodorized stock and recirculated as deodorized stock to said second evacuated chamber to undergo heat exchange with said feed stock.
