More Information
Summary:The invention relates to a gas condensate eliminating method, especially a low-pressure difference throttling natural gas condensate eliminating method, at least composed of a heat exchanger, a throttle valve and a separator, and its characteristic: A. the heat exchanger is a plate-fin heat-exchanger and the pressure difference between the front and back ends of the throttle valve connected to the back end of the heat exchanger is between 0.3 and 1 Mpa; B. at the said pressure difference, the difference between the gas source-end gas temperature of the heat exchanger and the input-end gas temperature of the throttle valve is between 20 and 80 deg.C.
