摘要: The present disclosure provides a gas liquefaction separator, a gas liquefaction recovery system, and a method for separating and recovering ethylene oxide. The gas liquefaction separator includes a housing, a blocking plate, a gas baffle, and a liquid collector, the latter three being located inside the housing. The liquid collector—an outer edge of which is connected to an inner wall of the housing—is located below the gas baffle, which is located below the blocking plate. The liquid collector includes a first flow guide surface, on a bottom portion of which is disposed a first hole. The gas baffle—an upper surface of which forms a second flow guide surface and an outer edge of which has a protrusion(s)—is connected to the first flow guide surface through the protrusion(s), thereby forming a second hole between the outer edge of the gas baffle and the first flow guide surface.

摘要: A method for producing epoxyalkane includes the step of separating, in a separation column, a stream containing epoxyalkane, extractant, and diol. The separation column operates under conditions so as to enable the extractant and the diol to form an azeotrope, and a stream containing extractant and binary azeotrope is extracted from the side-draw of the separation column to liquid-liquid separation. The method can be used for the industrial production of epoxyalkane.

摘要: A method for producing propylene oxide involves an oxidation step, a distillation step, an epoxidation step, and a separation step. The distillation step involves distilling the reaction mixture containing cumene hydroperoxide to separate it into a concentrate containing cumene hydroperoxide and a distillate. The reaction mixture is continuously distilled so that the ratio of the flow rate of the distillate to the flow rate of the reaction mixture to be distilled is 0.037 to 0.13. The epoxidation step involves obtaining a reaction mixture containing propylene oxide and cumyl alcohol by contacting the concentrate with propylene in the presence of a catalyst in one or more reactors to cause a reaction between propylene and cumene hydroperoxide in the concentrate, in which the outlet temperature of the final reactor is adjusted to 115° C. or more and less than 140° C.

摘要: Plasticizers are purified by contact with a coalescing filter to effect removal of ions, metals, monohydric alcohols, and polyhydric alcohols. The resulting purified plasticizer compositions are suitable for use in PVC due to their low levels of impurities that reduce PVC utility.
