Abstract: This invention is directed to a method for producing ethylene oxide comprising feeding ethylene, high purity oxygen and a ballast gas with a recycle gas in a catalyst filled reactor to form a gaseous mixture; passing the gaseous mixture from the reactor to a recovery unit to selectively separate ethylene oxide and carbon dioxide containing gas; passing at least a portion of the carbon dioxide containing gas to a stripping unit to selectively separate carbon dioxide and a waste gas; passing at least a portion of the waste gas to purge and another portion for recycling as the recycle gas; and recovering ethylene oxide from the recovery unit.

Abstract: The invention is directed to a liquid phase oxidation process, wherein a first oxygen-containing gas is injected into the lower portion of a bubble column reactor vessel containing an oxidizeable organic liquid. A second oxygen-containing gas is further injected into the reactor at a point or points wherein the liquid is substantially depleted in dissolved oxygen prior to said injection. Oxygen from both the first and second oxygen-containing gases is used to oxidize the organic liquid.

Abstract: A method for producing vinyl acetate using ethylene, acetic acid and argon containing oxygen that maximizes selectivity and minimizes ethylene loses to purge.

Abstract: Heterogeneous vapor phase oxidation and other reactions are carried out at the surface of a solid catalyst, with both gaseous reactants and the solid catalyst being dispersed in a recirculating liquid solvent. Reaction and product absorption are combined into a single processing step, with enhanced catalyst performance, and product selectivity and product yields, enhanced mass and heat transfer characteristics and reduced risk of forming explosive mixtures in the course of a particular reaction.
