Patent ID: 8281820

Claim:
A method for discharging a compressed fluid from containment, comprising: providing a flow path between a containment system and a receiving system for discharging a compressed natural gas that is contained in the containment system into the receiving system, wherein the pressure in the containment system is higher than the pressure in the receiving system, wherein the containment system has an upper portion and a lower portion, wherein the compressed natural gas is liquid and/or more dense in the lower portion of the containment system than in the upper portion, and wherein the flow path connects to the lower portion of the containment system; and allowing flow to occur from the lower portion of the containment system to the receiving system prior to allowing flow to occur from the upper portion of the containment system, while not adding any fluid into the containment system, until the pressure in the containment system drops to a point such that the actual flow rate from the lower portion of the containment system is at or below a desired flow rate.
