Abstract
In a method for deaerating a liquid the liquid is pressurized to a pressure above atmospheric, after which it is guided to an upstream end of a nucleation valve. A low pressure resides on the downstream end of the nucleation valve and as the liquid passes the valve, bubble nucleation is initiated, forming the first step in a deaeration process. According to the method the temperature and pressure on the downstream side of the valve is controlled such that the static pressure is above the saturation pressure, while the lowest pressure as the liquid passes the valve is below or equal to the saturation pressure.
