VCM Plant-120,000 MTPY

VCM plant was designed with initial technology developed by SIR, and was similar to Goodrich fluid bed catalyst process, using air for oxy-chlorination. Later, plant was converted to pure oxygen oxidation.

Nominal production capacity is rated at 120,000 MTPY, but plant could easily be expanded to 160,000 MTPY, and with further improvements could reach 250,000 MTPY. 

Battery limits include storage of EDC and VCM, in addition to waste water treatment, plant incinerator, and control motor centre.

Operations are managed from remote control room, by means of Metzo (Jap)  DCS, revamped and updated in year 2003. Originally DCS was Valmet. All technical documentation is available. Asbestos inventory is available.

Plant shut down occurred in year 2009, and equipments are kept under N2 atmosphere.
Only one, or two, vessels contain some EDC  and are planned to be emptied and cleaned by plant operators, shortly.
