Phase equilibrium data for the C2-hydrocarbons and the solubilities of mixtures of these gases in acetone at low temperatures have been obtained at atmospheric pressure using a flow cell. The data was shown to be thermodynamically consistent, but attempts to provide a theoretical correlation for the results were unsuccessful. Absorption and distillation columns were designed, using, the experimental data, to enable C2-hydrocarbon feedstocks to be separated into their constituents. Sieve-plate columns were erected and trials were made to substantiate the design calculations and to permit a comparison of the proposed separation methods. For high acetylene content feedstocks, absorption was shown to be satisfactory. for low acetylene content feedstocks, distillation and distillation with a side-stream provided good solutions and a computer programme was written to permit verification and extension of the results to the desired product purities. The programme reproduced the experimental results, but failure to predict plate efficiencies in the region of the pure components and to obtain a satisfactory correlation for the experimental phase equilibrium data made a complete solution impossible. Nevertheless it is considered that sufficient data has been presented to provide an adequate foundation for the design of physical separation processes to solve the problem under consideration.
