Abstract: A filling station for filling a liquid cryogenic refrigerant from a supply tank to a receiver tank, the filling station comprising a flash tank between the supply tank and the receiver tank, adapted to de-pressurize the refrigerant that is transferred from the flash tank to the receiver tank, resulting in formation of a liquid cryogenic refrigerant phase and a vapour cryogenic refrigerant phase within the flash tank, and to phase separate the liquid and vapour cryogenic refrigerant phase, and a pump between the flash tank and the receiver tank, adapted for pumping the refrigerant out of the flash tank to the receiver tank, wherein the flash tank has a size and the pump has an outflow of refrigerant such that the ratio between the size of the flash tank and the outflow of refrigerant out of the pump is equal to or more than 1.

Abstract: A method for distribution and sales of cryogenic fluids, in particular CO2, includes a system of filling stations for cryogenic fluids provided in connection with ordinary service stations for the filling of fuels to motor driven vehicles. The filling stations for cryogenic fluids include at least a stationary storage tank (1) and dispenser (3) with flexible hoses (4, 8) and a quick connector (5) for easy connection to a mobile tank (2) on a truck or the like. The filling station further includes a pressure/flow control column (27) with a phase separator (20) provided between the stationary storage tank (1) and the dispenser.
