Treatment of liquefied gas at the top of the stabilizer during shutdown periods
Thread Content
How is the liquefied gas at the top of the stabilizer handled during shutdowns?
During shutdowns, the liquefied gas at the top of the stabilizer is generally discharged through a safety venting system, or collected and stored to prevent safety issues caused by excessive pressure. It may also be circulated back to the front end of the stabilization system for further processing. The specific handling method needs to be determined based on the actual conditions on site and the design. .
For the liquefied gas cooling process, pressure relief is achieved only through the tower top safety valve; in practice, it is not possible to completely release all the liquefied gas, and a large amount of it remains.
If it is difficult to relieve pressure solely by relying on the tower top safety valve, consider using a mobile gas burner (flare) to burn off the emissions, or transferring the liquefied gas to a safe storage facility through temporary pipelines. Ensure that the relevant safety procedures are followed during operations to avoid environmental pollution and safety accidents. If the volume is large and the safety risks are high, a professional team may be needed to assess and handle it. .
