When producing synthetic ammonia using the Lurgi process, what should we pay attention to when switching gas with low A conductivity? When the pressure is well controlled: should it be introduced in fractions or in one pass?
I think it should be added slowly at one time. If the liquid level is not adjusted well during the process, you can stop for a short time to allow the liquid level on the tray to drop and the liquid level in the tower tank to rise.
First use the bypass valve of the inlet valve to pressurize the system. After the pressure is balanced, slowly open the inlet valve and pay attention to changes in the system liquid level, temperature, and pressure. To guide air, open the valve slowly
