ABSTRACT:
The present invention is directed to an analyzer for measuring the vapor pressure of a hydrocarbon liquid. The analyzer includes a pressure measuring system connected to an air saturation system having a circulation chamber with opposing first and second ends. A first opening is disposed toward the first end and a second opening is disposed toward the second end. A plumbing system connects the first and second openings. A pump moves the hydrocarbon liquid through the plumbing system from the first opening to the second opening so as to saturate the hydrocarbon liquid with air. The air saturation system has a cooler for cooling the hydrocarbon liquid and the pressure measuring system has a heater for heating the hydrocarbon liquid. The pump may be a piston actuated pump or a motor-driven pump and the plumbing system may include an aeration chamber.
