Conclusion The results obtained from operating a pilot plant, using the ion exclusion process for the separation of crude glycerin from its dissolved solids, proved to be predictable according to previous publications. The operating variables investigated were: temperature, flow rate, nonionic concentration, ionic concentration, and feed volume. No serious problems were incurred as a result of scale up from the 0.6‐in. diameter laboratory column to the 12‐in. diameter pilot plant and laboratory data were duplicated in the pilot plant. The product obtained from the ion exclusion pilot plant, which was finished by ion exchange and evaporation, meets and/or exceeds U.S.P. specifications for CP glycerin. A cost analysis based on the above process, which includes operational cost, equipment, and resin amortization, indicates that CP glycerin could be produced for one cent per pound.
