Dr. Swapneshu Baser, alumnus of Chemical Engineering Department, has received another accolade for himself and ultimately for MGM’s Jawaharlal Nehru Engineering College famously known as JNEC, Aurangabad. He has added another patent to his name. However, before discussing more about his innovation, let’s get to know more about him first. Dr. Baser completed his undergraduate studies from JNEC in the year 1987 and later went on to do his postgraduate studies from IIT, Delhi and his Doctoral studies from IIT, Bombay.
Apart from working as an Adjunct Professor at IIT Bombay, he has won many national and international recognitions and awards for his contribution in developing innovative and environment friendly chemical processes. But the important award he cherishes most is the award received by the hands of the honorable President of India, late Dr. A.P.J. Abdul Kalam for his contributions in improving Supercritical Fluid (SCF) Extraction technology.
Dr. Baser has been very instrumental in entrepreneurial activities from the early stage of his career and in the year 1999, he founded Deven Supercriticals Pvt. Ltd. (DSPL). Over the years DSPL has taken up challenges to successfully design, manufacture and supply wide range of SCF processing equipment along with complete technical support for process / product development, process optimization and efficient operation of the plant. DSPL is catering to technical needs of clients in India and abroad ranging for number of products covering areas like spice oils & oleoresins, herbal extracts, natural colors, perfumes, natural preservatives, pesticides, pharmaceuticals, leathers, textiles etc.
Dr. Baser has number of patents on his name and recently has obtained another one for an incredible innovation of SCF technology for textile industry. Considering the intensity of environmental pollution in textile industry due to amount of water required for dyeing of threads and woven cloth and its subsequent cleaning, which even after waste water treatment ultimately end up carrying traces of synthetic dyes in effluent. So it is always important that textile industry uses minimum process water or no water at all for at least dyeing processes. Dr. Baser identified this opportunity and developed an innovative process of dyeing textile products using carbon dioxide as supercritical fluid to be used as an alternative to water.
Major advantages of supercritical carbon dioxide based Textile Dyeing process is primarily elimination of pollution due to waste water streams and at the same time process having increased economic viability and zero discharge. Technically speaking, the primary objective of his innovative work was to develop an improved dyeing process that facilitates interaction of the dye molecules with the textile material, so as to increase the rate and efficiency of dyeing process using supercritical fluids. This innovation has resulted in waterless dyeing process for dyeing of the textile materials with single or multi-colors in various shades, patterns, designs etc. in single step of dyeing.
Chemical Engineering Department, MGM University organized live Webinar of Dr Swapneshu Baser on 12 September 2020 at 3:00 pm. He talked about his innovations, his professional activities and how time spent at Jawaharlal Nehru Engineering College has contributed in his success journey.
