Bew Bleaching Material for Oil Refining

The traditional oil bleaching is essentially the process of decolourization. This is done by mixing the heated oil under vacuum with specially prepared earth that absorbs the colouring bodies and the the spent earth oil is filteres. The total requirement of the bleaching earth ion the country is approximately 50,000 tonnes annually. At present, the bleaching earth is largely imported.
Recently, a low cost alternate bleaching material has been developed at CIPHET, Ludhiana from abundantly available indegenous bio-resources with the objective of import substitution and reduction in the cost of bleaching and loss of oil absorbed by the bleaching earth. The bleaching loss is estimated to be 1-2%. The technology developed at CIPHET is eco-friendly ans has the potential of employment generation. The technology has been transferred to M/s Star Polyfab for a period of five years.

The technology has been developed by Dr. S.M. Iliyas, Dr. S.K. Tyagi, Er. R. K. Vishwakarma, amd Dr. O.D.Wanjari.
