Protection scheme for chemical plant systems
Thread Content
After a chemical plant stops operating, system protection is required. Is there any information regarding such protection? Preferably solutions for hydrogen production plants at northern chemical factories. Thank you.
The system is protected with nitrogen, and the oxygen level is monitored regularly – that’s all that’s needed.
I mainly want to learn about the details of system protection in the north during winter.
In winter, it is essential to carry out comprehensive measures to prevent freezing and condensation in the system
Thanks for sharing, I’ve learned something new!:victory::victory::victory::victory::victory:
Nitrogen purging: When the system is shut down, after the flammable gas levels are confirmed to be within acceptable limits, the system is filled with nitrogen to maintain pressure (the pressure should not be too high, to prevent leaks caused by the contraction of the gasket materials when cooled). The device is protected using steam heating along with insulation material； On-site combustible gas detection is required ； Regular DCS checks, external operation inspections, etc
