Abstract
A process is disclosed for producing a displacement gas to be used in displacing a pressurized liquefied gas from one or more containers. A portion of the liquefied gas to be displaced is further pressurized and it is then separated into a first fraction and a second fraction. The first fraction is expanded by a suitable expansion means, and the expanded fraction is passed to a separation means to produce a liquid stream and a gas stream. The second fraction is heated to covert it to a vaporous product stream. A portion of the vaporous product stream is withdrawn, expanded, and passed to the separation means. A gas stream produced by the separation means is expanded, and it is then available for use as a displacement gas for displacing liquefied gas from one or more containers.
