While the basic principles behind any deodorizer are essentially the same, there are several types of systems used to perform these functions. General classifications include the batch, continuous, and semicontinuous operations. 

Activity Coefficient a The efficient removal of volatile substances during edible oil deodorization depends not only on their vapor pressure but also on their concentration in the oil. The theoretical principle of the deodorization process has already been described in many publications (2-4). All calculations start from the basic laws of Raoult and Dalton, which are valid for ideal mixtures. However, in practice, the mixture of a fatty acid and a vegetable oil has a nonideal behavior. Consequently, a so-called activity coefficient a was introduced and Raoult s law may be written as follows ...
