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.
