Wax De-oiling Technology for Production of Paraffin and Microcrystalline Waxes

This technology is for production of ‘Paraffin Wax’ and ‘Microcrystalline Wax (MCW)’ from petroleum streams. Paraffin Wax (PW) is used for making candles, polishes, food packaging etc., while Microcrystalline Wax (MCW) is used mainly in cosmetic industry.

CSIR-IIP has developed a ‘Wax De-oiling Technology’ to produce petroleum waxes from petroleum streams. 

Wax De-oiling Technology has a number of distinctive features. Some salient features of Wax De-oiling Technology are :

1. Lower solvent-to-feed ratio with prudent filtrate recycle
2. Optimum solvent dilution scheme combining delayed dilution
3. Controlled crystallization for producing larger wax crystals with narrow crystal size distribution
4. In this process, furnace was eliminated from solvent recovery system by applying pinch analysis which helped NRL to reduce carbon foot print considerably
5. Lower cost in comparison to foreign technologies and energy efficient process.
