On this base, the suggestion is put forward on optimization of azeotrope tower operation adjustment to reduce the operation cost. 在此基础上,提出了降低运行费用的共沸塔操作调整的优化方向。
Based on the characteristic that styrene can form ternary azeotrope with some special organic solvents and water, a new separation process for recovery of styrene in residue tar discharged from the bottom of styrene distillation tower has been developed. 利用苯乙烯能与某些特定溶剂及水形成三元共沸物的特点,开发出从苯乙烯蒸馏塔釜排放的残焦油中提取粗品苯乙烯的新工艺。
