DEHRADUN :The Council of Scientific & Industrial Research (CSIR) through its constituent laboratory Indian Institute of Petroleum (IIP), Dehradun, in association with the Engineers India Ltd (EIL) has won international competition to adopt the Wax Deoiling Technology at Numaligarh Refinery Ltd (NRL). The Wax Deoiling Plant is set up with an investment of 750 crore rupees at NRL – a subsidiary of Bharat Petroleum Corporation Limited (BPCL) – situated in north-east part of India.
The first batch of Paraffin Wax has been produced and regular production of Paraffin Wax is expected to start by the end of first quarter 2015. This commercialization of indigenous technology is in line with ‘Make in India’ initiative taken by the Government of India.The CSIR made the announcement on the eve of the national science day tomorrow. The Wax Deoiling Technology is used to produce waxes from petroleum streams
This newly set up plant will produce 50,000 MMTPA of high value Paraffin Wax and 4,500 MTPA of Micro crystalline Wax that will help cut down the wax import by 50 per cent and will save the foreign exchange of order of about 500 crores/annum. Besides, the production of Paraffin and Micro crystalline waxes at NRL, it will also help to add new high value wax products in refinery’s product slate and will contribute in enhancing the refinery’s profitability. Paraffin wax is used for making candles, polishes, medicines, food packaging, paints, leather etc, while Micro crystalline Wax is mainly used in cosmetic industry
Salient Features of CSIR-IIP & EIL Solvent Dewaxing-Deoiling Technology includes Lower solvent-to-feed ratio with prudent filtrate recycles, Optimum solvent dilution scheme combining delayed dilution, incremental dilution and cold dilution techniques for maximum gains, Controlled crystallization for larger crystals with narrow crystal size distribution, Low specific coke resistance and high slurry filterability,Two-stage filtration with balanced filter cycle, High wash efficiency energy efficient process with built in operational flexibility and continuous process back-up etc.
This wax plant will help to develop small-scale ancillaries and cottage industries in the nearby areas and will promote industrial development in the north-east region of India. This plant will also generate direct and indirect employment opportunities for local people, thereby improving their quality of life. The CSIR IIP-EIL-NRL wax technology also opens up opportunity for export of this indigenous technology, as a commercial reference of this technology is available now.
