Reduce Gas Entrainment In Liquid Lines

Follow these tips to properly size self-venting lines and vortex breakers

Tamagna Ukil and Thomas Mathew Reliance Industries Ltd.

Increased feed flow into any gas-liquid separator can lead to the entrainment of gases into the liquid lines. Such gas entrainment can lead to pulsating flows in the line, which can result in vibration and potentially destabilize the downstream processes. In many cases where GLS are provided with “gravity-flow pipelines,” the use of self-venting pipelines coupled with properly sized vortex breakers can mitigate the problem of entrainment of gases into liquid lines...
