Presented at meeting of the California Natural Gasoline Association. Increased extraction of propane of the required purity in absorption-gasoline plants may be achieved through changes in the fractionating absorber and its important adjuncts, the gas cooler and partial condenser. Design formulas are presented for the absorber, for the determination of liquid and vapor traffic, key temperatures, and other factors that relate to retention in the absorber and to rejection in the stripper with overall recovery. Plant design based on the formulas is applied to the recovery of 90% propane from a wet gas of specified composition, as an example. Product costs are shown lower than in most conventional plants handling on equal volume of gas and recovering gasoline and butanes only. The direct cost of production is calculated at $0.705 per gal. of total liquid products recovered.
