De-inventory safety standby systems may sit for years before use. In fact, unless they are intended for unit shutdowns as well, the objective is never to activate them. However, when called upon, the systems should handle extreme circumstances reliably and with minimum operator intervention. Liquid de-inventory systems fall into four categories: pressurized; displacement; gravity drain; and pump-out. In pressurized systems, a high-pressure reservoir of gas forces liquid from the system into a reservoir. In displacement systems, a liquid displaces the process flow and forces it to a destination. In gravity drain systems, liquid can empty into a reservoir at a lower…
