ABSTRACT:
A lightweight, portable, unmotorized apparatus for recovering condensable halocarbons is described. The device is comprised of two containers. The first container, which is substantially cryogenic, is adapted to hold refrigerant; this container is comprised of a valve and a refrigerant line. The refrigerant line from the first container is passed in contact with a second container, and the in such line is allowed to vent to an area of relatively low pressure. As the refrigerant is passed to the area of lower pressure, the second container is cooled. The second container is connected to a vessel, which contains the condensable gas to be recovered.
