摘要
焦炉煤气制甲醇传统工艺甲醇转化率低、设备能耗高、资源浪费严重、易造成环境污染,因此本文通过对传统工艺进行分析,选取了研究设备,使用Aspen Plus进行工业过程模拟,建立了较为准确的焦炉煤气制甲醇工艺模型,提出了基于副产蒸汽降级的制甲醇优化工艺,通过降低冷却剂温度至187℃,实现了甲醇产量增加3%、能量节约28.2%、收入增加5.397万亿美元/a。
The traditional process of coke oven gas to methanol has low methanol conversion rate,high equipment energy consumption,serious resource waste,and is prone to environmental pollution.Therefore,this article analyzes the traditional process,selects research equipment,uses Aspen Plus for industrial process simulation,establishes a more accurate coke oven gas to methanol process model,and proposes an optimized methanol production process based on by-product steam degradation.By reducing the coolant temperature to 187℃,methanol production increased by 3%,energy saved by 28.2%,and revenue increased by 5 397 billion US dollars/a.
