    摘要: A process for the recovery of maleic anhydride from the gas produced by the catalytic oxidation of hydrocarbon, n-butane or benzene, is characterized by: a) High efficiency in maleic anhydride recovery b) Reduced formation of maleic acid and fumaric acid c) Reduced maintenance, thanks to the prevented formation of solid deposits in the absorber and in other related equipment.
