Abstract:
1. A method for loading a compressed fluid into a container, comprising: injecting a displacement fluid into a first tank, the first tank having an upper portion and a lower portion, wherein the displacement fluid is a gas; injecting the displacement fluid and/or a compressed fluid into the first tank until a desired pressure is reached in the first tank cooling and injecting the compressed fluid into the lower portion of the first tank; bleeding the displacement fluid out of the upper portion of the first tank after the desired pressure is attained while continuing to inject the compressed fluid into the lower portion of the first tank; adjusting the flow rate of the displacement fluid bled out of the upper portion of the first tank to maintain the pressure in the first tank within a desired range about the desired pressure; and cooling and injecting the compressed fluid into the lower portion of the first tank until a desired mass of the compressed fluid is contained in the first tank while bleeding the displacement fluid out of the upper portion of the first tank, wherein the pressure of the desired mass of the compressed fluid contained in the first tank is between 100 and 2,000 psig.
