摘要： The present invention concerns a process for removing impurities from air to be used in the oxidation of cumene, which process comprises providing an air feed containing air and at least one acidic component, contacting the air with an aqueous caustic solution, which contains at least one alkaline compound whereby to neutralize the acidic components in the air feed, e.g. to form inorganic salts, separating a first purified air stream from the caustic solution, contacting the first purified air stream with fresh water to dissolve residual caustic solution and/or salts in the water, and separating a second purified air stream from the water containing residual caustic solution and salts. Further, the present invention concerns a purification column for use in purifying air.

摘要： A process for oxidizing cumene to cumene hydroperoxide using an oxygen containing gas, which process composes - conducting a cumene feed and an oxygen containing gas feed to at least the first oxidation reactor in a series of 3-8 reactors, thereby forming an oxidation mixture, and - conducting the oxidation mixture from one oxidation reactor to at least one subsequent reactor, wherein - the reactors are operated with reducing liquid levels; - the oxidation is operated as a dry oxidation, whereby the only gaseous feeds conducted to the oxidation reactors are the cumene feed and the oxygen containing gas feed; - the oxygen containing gas feed is washed with caustic and then with water to remove all acidic or caustic traces before conducting it into an oxidation reactor; - the pressure within each oxidation reactor is in the range of 0-10 barg; - the off-gases from the top section of each oxidation reactor are separated and cooled, whereby a condensate containing unreacted cumene is formed, and - washing the condensate and recycling at least a part of it to at least the first oxidation reactor; - the non-condensed off-gases are treated in a thermal oxidizer; and - the first reactor in the series of oxidation reactors has a liquid inventory of 30- 300% larger than in the remaining reactors, preferably 50-100%, or the first two reactors in the series of oxidation reactors have a liquid inventory of 30— 300% larger than in the remaining reactors, preferably 50—100%.
