System Vent Operation
No adjustment is necessary for operation of the vent system discharge. Once the nitrogen supply begins
flowing into the separation tank and is vented into the facility flare header. During plant upset conditions
when the flare header pressure may rise above the permissible operating discharge pressure, the outlet
check valve will close and isolate the ThermoJ
et
from the flare system. The ThermoJ
et
will continue to
operate while a slight pressure accumulates in the separation tank. If the separation tank pressure rises
above 5 PSIG (0.34 BAR), pressure relief/safety valve will vent the exhaust to the vented oil reservoir. The
pressure relief/safety valve precludes the potential for over-pressurizing the separation tank.
To accommodate any condensate removed by the ThermoJ
et
while gasses are exhausting to the flare
system, a liquid drainer is furnished to route the condensate to the condensate purifier assembly. The
excess oil is removed from the condensate and the water is properly routed to the sewer system.
Relief valve vents flow to supply
reservoir to prevent over
pressure of the separation tank in
the event where the flare
pressure increases
Check valve prevents separation
tank from being exposed to
excess flare pressure
A liquid drainer routes the condensate
to the condensate purifier assembly
Condensate purifier assembly
discharge is routed to oily water
collection.
