Parking swap
Thread Content
Due to the high environmental pressure at present, parking for maintenance has become a very tricky issue. Gas generation cannot be vented; inert gas cannot be produced, and the subsequent processing stages cannot be carried out. Even when the plant is shut down, no work can be done. I would like to ask everyone: when it comes to gas generation and compression, how do you carry out the gas displacement?
No, you can just replace it with steam directly
Full plant passivation replacement is adopted, as long as the hydrogen extraction unit is operational. Gas is generated by adding wood; the hydrogen-rich exhaust gas is sent for compression, while the permeate vapor is fed into the boiler (in the air blowing and recovery section). This process has been used before.
Vaporize it with liquid nitrogen to turn it into gaseous nitrogen for displacement
You have several systems, while we have two; we have established a comprehensive inert gas network dedicated to use in maintenance and replacement tasks
