additionally, cpa equation was used to simulate the dehydration process of natural gas with chilled methanol distillation and provide reference data for the design of process.
并把cpa方程应用于汽提冷甲醇天然气脱水工艺的模拟计算,为工艺设计提供了必要的参考数据。
generally the crude methanol cannot meet the operation requirement so methanol distillation is needed.
合成的粗甲醇浓度一般不能达到使用要求,所以需要对粗甲醇进行精制。
industrial practice concluded that the 2-column single-effect methanol distillation process, which has been widely used in china, is simple and cheap, easy to control, but consumes too much energy.
多年来生产实践证明,我国普遍采用的甲醇双塔精馏工艺具有流程简单,操作方便,运行稳定的优点,但存在能耗高的缺陷。
the process design is completed for the key equipment of heat exchanger for the process streams of inlet and outlet, dme rectifying tower and methanol distillation tower.
还完成了关键设备进出气换热器,dme精馏塔和甲醇蒸馏塔的详细工艺设计。
