To properly vent discharge gas to the plant’s flare system, the exhaust to flare piping is connected to the 1/2
PSIG (0.04 BAR) spring loaded pressure check valve located on the vent connection of the ThermoJet Oil
Purifier. Exhaust to flare piping must be DN20 (3/4” NPT) or larger. Exhaust to flare piping must extend
vertically at least 4.5 m / 15 feet above the ThermoJet Oil Purifier.
Piping for the pressure relief/safety line must be routed back to the vented oil reservoir from the pressure
relief/safety valve. The pressure relief valve is set to relieve at 0.35 BAR (5 PSI).
The safety relief valve (set 0.35 BAR /5 PSI).connection is 1” FNPT. For safety reasons due to the upset in
the flare system, piping must be routed from the safety relief valve connection back to the vented oil
reservoir or to an atmospheric safe area.
