Abstract

See full text

A method of proportionally mixing two fluids is provided. The method includes introducing a first fluid stream, introducing a second fluid stream, wherein the flow rate of the second stream is modulated by a valve, thereby producing a modulated stream, combining the first fluid stream and the second fluid stream, thereby forming a compounded fluid stream, introducing said compounded fluid stream into a fluid containment region, wherein a vapor fraction and a liquid fraction are formed, determining the composition of the vapor fraction, comparing the composition of the vapor fraction with a predetermined composition to determine a composition error, and modulating the valve to reduce the composition error to a predetermined error.
