When completed, the plant, located near Mumbai in the state of Maharashtra, will have a capacity of 160,000 mt/year, from 110,000 mt/year previously.
Market sources estimate that demand for PA in India is about 300,000 mt/year, more than 90% of which is met by domestic producers.
The other PA producers in India are Thirumalai Chemicals, which has a 140,000 mt/year plant at Ranipet near Chennai; and Mysore Petrochemicals, a sister company of IG Petrochemicals, which has a 12,000 mt/year plant at Raichur in the southern state of Karnataka.
