Abstract
A continuous flow of cooling liquid is provided to a liquid ring pump conveying a flow of gas, such that the cooling liquid simultaneously acts as the working liquid in the pump. Gas that becomes dissolved in the cooling fluid during pumping is separated therefrom and is returned to join the pump gas inlet flow, and the cooling liquid is thereafter discharged to carry away any heat picked up from the pump. In an aspect of this invention, the degassing of dissolved gas from the exhaust cooling water flow leaving the pump is facilitated by forming a spray in a low-pressure degasser connected to the pump gas inlet.
