Sulpholane Technology

I have seen this technologyin the CSIR Technofest 2010, showcased by Council of Scientific and Industrial Research, New Delhi, at India International Trade Fair during November 14-27, 2010 New Delhi, India. I understand that "Sulpholane Technology" was developed by Indian Institute of Petroleum, Dehradun, India.

Sulpholane is a clear, colorless liquid commonly used in the chemical industry as an extractive distillation solvent or reaction solvent. Sulpholane was originally developed in the 1960s as a solvent to purify butadiene. Sulpholane is an aprotic organosulfur compound, and it is readily soluble in water.

Sulpholane is widely used as an industrial solvent, especially in the extraction of aromatic hydrocarbons from hydrocarbon mixtures and to purify natural gas.

Sulpholane which was developed by IIP, dehradun is having these applications

Solvent for extraction processes such as aromatics from catalytic reformate, hydro treated pyrolysis naphtha and kerosene

Used for removal of acidic gases like H2S, CO2 and mercaptans from variety of sour gas streams including natural gas

This technology has already been commercialized and technology transferred to Casil Health Products Limited, Ahmedabad, India. Casil Health Products Limited has the 300 TPA plant in operation at, Kadi, Ahmedabad, Gujarat.

What are the Salient Features of this technology

This is improved Technology and has very Negligible side reactions.

Butadiene conversion >95%

Product purity >95%

This technology has very good performance results. This is a shining example where indigenously developed technology in India in Aromatics Extraction has been found at par with the similar technologies currently used in the industrialized developed countries.
