ABSTRACT:
Apparatus for exposing a fluid to a negative pressure particularly for degassing liquid containing a gas comprises a double acting piston/cylinder unit of which the cylinder is divided into two chambers by the piston, the volume of one chamber swept by the piston being lesser than that swept by the piston in the other chamber. An inlet for a fluid is made to said one chamber, a conduit connects the two chambers and an outlet is made from the other chamber. Valve means are associated with the conduits to permit controlled reciprocation of the piston within the cylinder and fluid passed from said one chamber to the other is exposed to a negative pressure in the other chamber, gas, in the situation in which the fluid is a gas-containing liquid, forming bubbles in the other chamber or, where the fluid is wholly liquid, a part of that liquid being vaporized. The contents of the other chamber are then passed through the outlet from the other chamber to, where the fluid is a gas-containing liquid, a bubble trap in which the gas is separated from the liquid or, where the fluid is wholly liquid, the gaseous phase or vapor will be condensed upon release of pressure and moved through the outlet to be used as required. In a variation the piston/cylinder structure is replaced by a simple receptacle provided with a flexible diaphragm.
