Abstract: A nickel deposition includes a reactor system for producing nickel carbonyl and storing same as a liquid, a plating system where the liquid carbonyl is vaporized and applied to product and deposited thereon, with carbon monoxide being released in the process, a reclaim system for cooling the gases received from the plating system and cooling them to a temperature just above its freezing point to condense out and recover the liquid carbonyl, said reclaim system including a reclaim condenser, and a vapor recovery system including a gas receiver for receiving vapors from the reclaim system. The vapor recovery system includes a first stage compressor operatively connected to the first stage receiver for pressurizing the vapor to about 25 PSIG, and a first stage condenser operatively connected to the first stage compressor for cooling the vapors. A conduit communicates the vapor recovery system to the reactor system for forwarding the cooled vapors to a recycle pump receiver in the reactor system.
