Abstract

This paper describes the methodology and results of a simulation of an oil purification process used by a food processing company in Toronto, Ontario. The process involves reacting a mixture of edible oils with a caustic solution to precipitate out various free fatty acid and gum components in the oils in the form of soap solids. The process is discrete in that batches of crude oil are processed individually but the processing of each batch is done on a continuous basis. The simulation model developed for this process simulates one crude oil batch at a time. Thus the model simulates an essentially continuous operation. The success of GPSS, a discrete event simulation language, in simulating this continuous process forms the basis of this paper.
