Abstract
A liquid CO.sub.2 storage vessel system for user sites, which receives warm CO.sub.2 and then cools the liquid CO.sub.2 to temperatures below -25.degree. F. before further use. The cooled liquid CO.sub.2 can be at temperatures and pressures of near equilibrium conditions or at sub-cooled conditions. Cooling of the liquid CO.sub.2 is conducted by CO.sub.2 vapor removal from liquid CO.sub.2 ; and is independent from the CO.sub.2 use, so cooling can be conducted during both normal and off hours. The storage vessel can be safely filled from most existing delivery vehicles, and the previously cooled liquid CO.sub.2 in the bottom of the storage vessel can be prevented from mixing with the warmer being-delivered liquid CO.sub.2, so the temperature of the liquid CO.sub.2 immediately going to use is little effected by the delivery being conducted.
