Vinyl Chloride Monomer Production

Minimize

 

Vinyl Chloride Monomer (VCM) production using the mercury catalyst process is the second largest demand sector for mercury globally (estimated at 570-800 tonnes annually in 2008). The process has emerged as a cost effective production technique for countries with high availability of acetylene over ethylene as raw materials (namely in China and Russia). It is believed that China represents 80-90 % of global capacity with 89 facilities currently identified.  UNEP has collaborated with China on this important topic since 2008.
