| 摘 要： | 以改进的前脱乙烷流程为基础,讨论了中冷油直接吸收法和中冷油补充回流法回收甲醇制丙烯(MTP)装置脱甲烷塔尾气的可能性。模拟结果显示,中冷油补充回流法能够有效地回收尾气中夹带的吸收剂和少量乙烯组分,降低产品气压缩机及丙烯制冷压缩机功耗。以1.7×106 t/a MTP装置为例,当采用中冷油直接吸收法时,MTP装置双机轴功率为20 537 kW, 分离工段尾气中乙烯损失为48 t/a、吸收剂损失为2 104 t/a;当采用中冷油补充回流法时,MTP双机轴功率为20 549 kW,分离工段尾气中乙烯损失为38 t/a、吸收剂损失为410 t/a。

| Abstract: | Based on the improved front-end deethanizer process, the methanol to propylene (MTP) demethanizer exhaust recovery process was discussed with intercooled oil direct absorption method and cold oil supplement reflux. The simulation indicates that cold oil supplement reflux can effectively recycle the absorbent and ethylene from the deethanizer exhaust, and cut down the duty of product gas compressor and propylene refrigeration compressor. Taking 1.7×106 t/a MTP device for an example, for inter cooled oil direct absorption method, C2H4 loss of demethanizer exhaust is 48 t/a, absorber loss is 2 104 t/a and dual compressor power consumption is about 20 537 kW. Meanwhile, for cold oil supplement reflux method, C2H4 loss of demethanizer exhaust is 38 t/a, absorber loss is 410 t/a and dual compressor duty is about 20 549 kW. |
