摘要/Abstract

摘要： 通过PRO-II流程模拟考察了丁烯氧化脱氢制丁二烯装置水洗单元的工艺操作条件对酸、醇、醛、酮等含氧有机物脱除效果的影响。模拟结果表明，在水冷塔顶洗水温度<20℃、水气比0.5～0.6，洗醛塔操作压力0.6～0.8MPa、塔顶洗水温度10～20℃、水气比0.7～1.0的适宜工艺条件下，水洗后生成气中酸、醇、酮可以完全脱除，乙醛、丙烯醛含量（φ）小于10*10-6

Abstract: The influence of process conditions of the washing unit in oxidative dehydrogenation of butylene to butadiene on the removal effect of organic compounds such as acid, alcohol, aldehyde and ketone was studied through process simulation with PRO-II software. The results indicated that the oxygen-containing organic compounds in effluent gas from the oxidative dehydrogenation reactor can be effectively removed, the acid, alcohol and ketone can be totally removed and the concentration of acetaldehyde and acrylaldehyde in the gas stream was less than 10 ppm(v) when the water temperature is below 20℃ and the mass ratio of water to feed gas is 0.5~0.6 in the cooling column, and the operating pressure is 0.6~0.8 MPag, the overhead temperature is 10~20℃ and the mass ratio of water to feed gas is 0.7~1.0 in the aldehyde removing column

Key words: butylene, butadiene, oxidative dehydrogenation, washing process, process simulation, organic compounds removal
