Abstract
A pressurized container (10, 20) for containing oil and a gas dissolved therein at a constant overall average pressure at a pressure above atmospheric pressure comprising a means (11a, 11b, 11c, 11d, 21a, 21b, 21c, 21d) for introducing a local area of reduced pressure within the oil. Preferably the local area of reduced pressure result in the gas dissolved in the oil evolving from the oil. This enables gas to be evolved from the oil without needing to reduce the pressure of the entire volume of oil which the gas is to be evolved from. The evolved gas and remaining oil occupy a greater volume than did the gas containing oil and consequently the pressure in the vessel will increase. This will allow the gas to be drawn off while the overall pressure of the container (10, 20) is maintained.
