This system meets the requirements of the API682 standard, is mainly used to provide buffer gas for the plan72+75 tandem dry gas seal, dilute the dangerous medium leaking from the main seal and take it to the designated discharge line.
The buffer gas pressure must be lower than the seal chamber medium pressure. It suits for the less volatile hydrocarbon medium above C4.
This system is equipped with pressure, flow and liquid level display, and can be remotely monitored by pressure and level switch/transmitter. It is in integration design, and easy to install and operate, no maintenance is required during use.
1. The volatile medium contains less volatile components above C5;
2. The non-volatile fluid contains giant gas H2S, such as rich amine liquid, sulfur-containing sewage, ammonia water, etc.
