Petrochemical industry is closely linked to the socio-economic aspiration of people and petrochemicals
have become now a part of life and providing the basic needs of mankind. Starting from synthetic fiber
to polymers, synthetic rubber, explosive, dyes intermediates, pharmaceuticals, pesticides no industrial sector is left where the petrochemicals are not used in some or other forms. Quantitatively, 95% of the organic chemicals are now based on petrochemicals derived from natural gas and petroleum feedstocks. Now the petrochemicals have virtually replaced the original natural feedstocks oil, fat, coal and molasses. Petrochemical Industries have undergone tremendous growth and modernisation. Since its birth in 1920 when first petrochemical isopropyl alcohol was manufactured from propylene obtained from cracking plant of petroleum refinery, there has been continuous upgrade in the process technologies and now new bread of petrochemical complexes are available with much higher capacities than what it was available in early sixties.
