All of the ion exchanger resins are temperature sensitive; therefore, a temperature diver valve bypasses letdown flow if the letdown heatexchangeroutlet temperature rises to a predetermined value.
所有的树脂床对温度都有要求,因此当温度超过预定值时,下泄流将旁通净化床运行。

The process design is completed for the key equipment of heatexchanger 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。

There are small temperature and pressure difference in steam inlet and outlet of heatexchanger, and big heat transfer surface.
