With the improvement in the specifications of MS and HSD where Sulphur content has been reduced, the Refineries have started producing Sulphur as a by-product. This Sulphur has a purity of about 99.9 %. Sulphur is sold in molten and solid form from our Mumbai and Kochi Refineries respectively. Most of our customers use Sulphur for manufacturing Sulphuric Acid or in the manufacture of Fertilisers.
