ABSTRACT:
A method and apparatus for recovering condensable vapor which is expelled from a container during filling by collecting and compressing the vapor after which the compressed vapor is cooled by cooling means. Upon cooling, a portion of the vapor is condensed after which the condensate is separated from the vapor in a separator. The vapor portion is then placed into heat transfer relation with heat exchange means which is operable to further cool and condense the vapor. The heat exchange means uses a portion of the vapor as the coolant after the vapor has been expanded through expansion means to effect cooling of the coolant vapor. The vapor used as the coolant is then conducted to a point of use. The recovered liquefied portion of the vapor can be returned to the container from which the vapor was displaced.
