Two phase, Co sub 2 storage tank
This patent describes a system for delivering either equilibrium or subcooled liquid carbon dioxide from a single tank. It comprises: an insulated tank for holding liquid CO{sub 2} to a depth of at least about 6 feet, inlet means for supplying CO{sub 2} to the tank, lower outlet means for delivering liquid CO{sub 2} from the tank, means for condensing CO{sub 2} vapor, which vapor is present in the head section of the tank, to maintain a desired pressure greater than 150 psig at the top of the tank, heat exchange means, a mechanical refrigeration type cooling unit including a refrigerant compressor and a refrigerant condenser, means for withdrawing equilibrium liquid CO{sub 2} from the tank, means for supplying withdrawn equilibrium CO{sub 2} to the heat exchange means, means connecting an outlet from the condenser to the heat exchange means so that condensed liquid refrigerant is caused to evaporate and to subcool liquid CO{sub 2} in the heat exchange means, vapor return means interconnecting a refrigerant vapor outlet and the suction side of the compressor, and means for returning subcooled liquid CO{sub 2} from the heat exchange means to a bottom region of the tank.
