2.1 Operating Principle
2.1.1 Once-Through Operation
Process inlet
Operating liquid inlet
Gas discharge
Continuous flow liquid system does not recover the operating liquid which flows out of
the separator drain having been separated from the discharge gases which vent sepa-
rately.
2.1.2 Partial Recovery (Open Circuit)
Process inlet
Operating liquid inlet
Gas discharge
50% of operating liquid recovered
Partial recirculation liquid system reduces the consumption of fresh liquid by recovering
and recirculating 50% of the operating liquid. Fresh operation liquid is added to the sys-
tem via the separator makeup connection to maintain constant operating liquid tempera-
ture to the vacuum pump.
2.1.3 Total Recovery (Closed Circuit)
Process inlet
Topping-up
operating liquid
Heat exchanger
Cooling water inlet and outlet
Gas discharge
Total recirculation liquid system recovers all of the operating liquid which is cooled by a
heat exchanger.
