纯化办法
吸附物 (Absorber)
MS (Molecular Sieve) = Absorber[吸附物 ] MS能去掉 CO2,H2O (不必加热) MS+H2O,CO2 → MS-H2O,MS-CO2 MS要再生课程 (在加热),所以不必更换 MS-H2O,MS-CO2 → MS,H2O,CO2
If heater is on,Compare Heating Temperature with Temperature Setting [HEATER在加热的话, 比较 加热温度 跟 温度设定] Check Whether‘PROCESS COLUMN’temperature is normal or not(≤50℃) [确认 纯化部分(吸附物)的温度, 它应该 50 ℃以下]
