Abstract: An apparatus for reclaiming contaminated refrigerant is disclosed. This apparatus contains three heat exchangers, the first of which cools the refrigerant to a temperature of less than about 32 degrees Fahrenheit, the second of which cools the refrigerant to a temperature of less than about -40 degrees Fahrenheit, and the third of which cools the refrigerant to a temperature of less than about -100 degrees Fahrenheit. The device also contains filtering means, for removing from the cooled refrigerant substantially all particles larger than about 0.1 microns. The device also contains gas removing means, for removing noncondensable gas from the filtered refrigerant.

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.
