Title: Innovations by Pinakpani Biswas in Clean Coal Technology
Introduction
Pinakpani Biswas is a notable inventor based in Jamshedpur, India. He has made significant contributions to the field of clean coal technology, holding three patents that focus on the recovery of organic solvents and the production of low ash clean coal. His work is particularly relevant in the context of environmental sustainability and energy efficiency.
Latest Patents
One of his latest patents is titled "Method of recovery of organic solvents required in refining of coal." This innovative method involves mixing solvent, co-solvent, and coal to create a slurry, which is then thermally treated under pressure and high temperature. The process includes passing the coal-extract through a membrane in an ultra-filtration unit to recover a major part of the solvent. The remaining thick clarified liquid is contacted with water to obtain precipitated coal, resulting in clean coal with very low ash content.
Another significant patent is the "Process for production of low ash clean coal from high ash coal with total solvent recovery." This process entails forming a slurry of coal fines in a solution of N-Methyl-2-pyrrolidone (NMP) and Ethylenediamine (EDA). The slurry is maintained in a reactor under specific temperature and pressure conditions, allowing for the separation of coal from solvent. The process emphasizes the recovery of 80-85% of the solvent, showcasing an efficient approach to coal refinement.
