Vessel for a cryogenic mixture and a process for drawing off the liquid
This patent describes a vessel for a liquid cryogenic mixture comprising: a liquid-containing reservoir having a neck; a heat exchanger which is located in the reservoir and has an inlet and an outlet, the inlet being in communication with a lower part of the reservoir through an element creating a pressure drop; a pressure raising circuit comprising an inlet end in communication with the lower part of the reservoir, a vaporizer located outside the reservoir and an outlet end communicating with an upper part of the reservoir; and a conduit for drawing the liquid mixture off the reservoir. The conduit is connected to the outlet of the heat exchanger so that, in use, the whole of the liquid which is drawn off passes through the element and through the heat exchanger.
