PRINCIPLE

A high-efficiency liquid jet ejector draws up non-condensable gases and condenses and/or neutralizes and/or absorbs vapours, which are then recovered in the separator tank, along with the motive liquid. A centrifugal pump recycles the motive liquid whereas non condensable gases are exhausted through the vent.

Temperature of the motive liquid in the tank is kept constant by a submerged heat exchanger.

Thus, the amount of residual vapours exhausted through the vent only depends on the cooling liquid temperature in the exchanger and on the kind of motive fluid (and its absorbent or neutralizing power).
