Abstract

The liquified gas to be purified is contained in a vessel under pressure. A second crossed circuit contains a gas which condenses in an exchanger contained in the liquid, giving up heat to the liquid. From the condenser the second circuit fluid passes next into an evaporator warmed by an air blast before passing back into the vessel to repeat the condensing operation. The closed circuit is regulated by a valve controlled by pressure variations in the vapour space in the vessel above the liquid to be purified.
