A question about hydrogen production processes
Thread Content
Why is heat tracing added to the pipeline section that leads the medium-pressure gas into the PSA? Isn’t it true that lower temperature and higher pressure are more favorable for PSA adsorption?
If the liquid separation in the separator tank is not effective after medium pressure conversion, water remains in the system, and freezing is likely to occur in winter; it is necessary to install heating
The answer is upstairs. It definitely won’t be in use in the summer.
The main concern is that moisture in the air during winter could cause pipe freezing. Heating will definitely not be used in the summer
This heating is for preventing freezing in winter, not for insulation.
It is mainly to prevent gas condensation and water content from affecting the adsorbent
