    摘要： Soap is separated from spent, cellulosic pulping liquor by strenuously percolating a gaseous, aliphatic hydrocarbon through a quantity of liquor volume under such temperature and pressure conditions that an equilibrious strata of liquid phase hydrocarbon is sustained on the surface of the liquor. Following strenuous combination and agitation, the gas-liquor mixture is allowed to settle so that the entrained, gaseous hydrocarbon and coagulated soap floc gravimetrically rises to the liquor surface and stratifies with the soap layer between the residual liquor solution and a liquid phase layer of hydrocarbon. Thereafter, the liquid hydrocarbon and soap layer are decanted away from the residual liquor solution and depressurized to vaporize the hydrocarbon leaving a reservoir of isolated soap.

    摘要： Pulping liquor borne solids are concentrated within an aqueous solution by a successive plurality of freezing steps wherein a discrete quantity of the solution is crystallized in each step by freezing. The water crystals from each freezing step are subsequently separated from the remaining liquid solution by screening and applying axial pressure to the crystalline mass. Greater efficiencies may be obtained in some cases by mixing or reslurrying a pressed, crystalline mass and pressing a second time. Another auxiliary separation step comprises a quiescent thaw of the crystalline mass from the first two press steps to permit additional dissolved solids to be drained away from the purified water ice.
