【摘要】 针对国外正丁烷氧化制备顺丁烯二酸酐(顺酐)工艺中的关键过程———吸收精制过程的技术特点、技术指标、产品质量、运行费用、溶剂消耗、蒸汽消耗、水消耗、电消耗等工业应用情况进行了全面的对比分析。指出溶剂吸收精制工艺优于水吸收精制工艺,其中,Conser工艺和Huntsman工艺的顺酐收率高,产品质量好,运行费用低。当顺酐作为合成1,4-丁二醇的原料时,采用Huntsman工艺可以省去精制塔,减少运行费用,具有综合优势。更多还原

【Abstract】 The recovery-purification system in the synthetic maleic anhydride(MA) production units by n-butane oxidation process at abroad were analyzed.The technical characteristics,technical specifications,product quality,operating costs,consume of solvent,steam,water,and electrical power,etc.were discussed.The results indicated that solvent recovery was superior to water recovery.The advantags of Conser process and Huntsman process had higher MA recovery,better quality and lower operating cost.When using maleic anhydride as feedstock of 1,4-butanediol,Huntsman process could save refiner column,reduce operating cost,and thus showed the overall advantage.更多还原
