ABSTRACT:
The present invention relates to a system for recycling a halocarbon composition which generally removes a halocarbon composition from a first source to purify the halocarbon composition and injects the halocarbon composition to a second source. The present invention is particularly useful for recovering and recharging of a commonly used halocarbon composition, Halon 1301. The invention comprises a first line having a first and second end where the first end of the first line is connected to the first source. The first source has the halocarbon composition contained therein. A vapor recovery unit connects to the second end of the first line for permitting the halocarbon composition to be transported from the first source to the vapor recovery unit for compression. A second line connects the vapor recovery unit to a recovery bottle. The recovery bottle is cooled by a cooling system integrally connected thereto for separating the nitrogen from the halocarbon composition. Once the halocarbon gas has been purified, a return line which connects the recovery bottle to permit the purified halocarbon composition to return to a second source for later usage.
