Chlorine processing evacuation

The subject of this paper is the investigation of chlorine-containing nickel silicide phases. These are obtained by the reaction of silicon-rich phases with nickel(ll)chloride in evacuated ampoules during sufficiently long testing periods (Eq. 3). The compounds thus obtained have chlorine contents between 0.02 and 0.6 wt. %. In generally, the chlorine-containing silicides and their route of formation can be used as models to describe the catalytically active phases in the hydrodechlorination process [4],... 

Process connections to the dry evacuation system are at the chlorine drying towers, the compressor system (coolers and compressors), liquefaction (phase separators and liquefiers), and secondary recovery systems. When an emergency spare tank exists, it is held under constant vacuum to be ready to receive chlorine as needed. The evacuation system, as its name implies, is not intended for systems under substantial pressure. These should be vented down through the process for recovery of the chlorine whenever possible. After the pressure has been reduced to a certain level, the evacuation system can take over.
