How to drain the liquefied gas inside a reflux pump at the stabilizer top when it is shut down for maintenance? What is the function of the pressure relief line at the pump inlet and how is it used? I’m very confused; please, experts, explain it to me
The pressure relief line at the pump inlet is used for draining during maintenance.
First, open the pressure relief valve to release pressure. When should the pump’s drain and vent valves be opened?

By feeling it with the hand, it can be confirmed that no fluid is flowing through the vent pipe, and the pressure gauge at the pump outlet has returned to zero； However, when the on-site drain valve is opened at this time, there is still a considerable amount of material present; the release of this liquefied gas needs to be done slowly, and it is best to use steam as a cover.
