Claim Text:
1. A method of proportionally mixing two fluids, comprising: a) introducing a first fluid stream, b) introducing a second fluid stream, wherein the flow rate of the second stream is modulated by a valve, thereby producing a modulated stream, c) combining the first fluid stream and the second fluid stream, thereby forming a compounded fluid stream, d) introducing said compounded fluid stream into a fluid containment region, wherein a vapor fraction and a liquid fraction are formed, e) determining the composition of the vapor fraction, f) comparing the composition of the vapor fraction with a predetermined composition to determine a composition error, and g) modulating the valve to reduce the composition error to a predetermined error wherein the first fluid stream and the second fluid stream are cryogenic fluids.
