ABSTRACT:
A gas/liquid phase separator includes a fluid inlet, a vapor outlet, a liquid outlet, and first and second valves disposed in fluid communication with the liquid outlet. Both valves are controllable in response to a fluid level in the gas/liquid phase separator. Both valves are further disposed in parallel fluid communication with each other. A method of controlling a liquid level in the phase separator includes sensing an amount of liquid in the phase separator, sensing a system pressure, and selectively opening a valve disposed in fluid communication with the phase separator to drain the liquid.
