Chlorine chain and production of polyvinyl chloride by salt extraction throughaccumulation of seawater from salt recovery  ponds with an area of ​​1500 hectares, is the main feed of Kimia production units. Kimia production units include / chloralkali / ethylene dichloride and vinyl chloride monomer, which produce caustic soda, sodium hypo chloride , ethylene dichloride, vinyl chloride monomer and hydrochloric acid after different chemical processes taken place on chlorine and sodium released from salt. Moreover, production of MTBE as an additive to gasoline is done by a unit of the same name at this company, which has a significant role in reducing atmospheric emissions and optimal gasoline combustion.
