醇烃化精制技术应用总结

简要介绍了醇烃化精制技术方案的确定和实施，阐述了醇烃化系统开车运行情况。醇烃化工艺与传统铜洗工艺的实际运行情况比较结果表明：醇烃化工艺无需为铜液再生供热，省去了铜洗装置运行时的冷量消耗；可利用“废气”副产甲醇，增加总氨产量；降低了铜、乙酸、液氨等原料消耗；没有再生气和废氨水产生，污染物减排显著；甲醇化系统和烃化系统出口气体中（CO＋CO2）体积分数分别为0．05％～0．30％和（5～10）×10^-6，吨氨总电耗下降4kW·h，吨氨汽耗减少129kg。

Sum-Up of Application of Refining Technology for Alcoholization and Hydrocarbylation

A brief summary is given of the determination and implementation of the alcoholization and hydrocarbylation refining technological plan, and the start-up and operation of the system. A comparison is given of the actual operation of the process with the traditional cuprammonium washing process and shows that the process needs no heating for the regeneration of the cuprammonium solution, omitting the cold consumption in the operation of the cuprammonium washing unit; ＂waste gas＂ may be utilized to byproduce methanol, increasing the total ammonia output; the consumption is lowered of such raw materials as copper, acetic acid and liquid ammonia; no regenerated gas and waste aqua ammonia are produced, and the pollutants are remarkably decreased for discharge; the exit gases from the methanolation unit and hydrocarbylation system contain in volume fraction of （CO ＋ CO2 ） of 0.05% -0.30% and （5 - 10） × 10 -6, respectively, the total power consumption per ton of ammonia decrease by 4 kW · h, and steam consumption per ton of ammonia lowers by 129 kg.
