    摘要: Glycerine is recovered from an aqueous waste stream containing but minor amounts of glycerine by the requested steps of; (1) evaporating, (2) contacting with pentanol, (3) separating precipitated salt, (4) flashing to remove pentanol, and (5) vacuum distillation. This process is particularly useful treating saline waste water resulting from the manufacture of epoxy resins.

    摘要: A cyclic process for the removal of H.sub.2 S from gas streams is disclosed, the process being characterized by reaction of the H.sub.2 S to sulfur employing polyvalent metal reactant solutions, and by a novel sulfur recovery scheme. Sulfur recovery, either before or after regeneration, is accomplished by separation of the sulfur-containing admixture into lean and concentrated solutions, and by extracting the concentrated solution with a compound having the formula C.sub.n H.sub.2n+1 OH, wherein n is a number from 4 through 18.

    摘要: A process is disclosed for demetallizing heavy hydrocarbon oils, by contacting the oil at elevated temperature with acidified active carbon. The process is particularly useful as a pretreatment of the heavy hydrocarbons for subsequent catalytic processes which are impared by metals such as nickel and vanadium.
