Revolutionizing carbon capture technology, we have successfully completed commercial testing of our proprietary CDRMax® carbon dioxide capture solvent technology at Solvay Vishnu Barium recently. The Commercial demonstration of CDRMax®, developed for treating industrial emissions, established breakthrough energy savings and robust performance in the industrial setting where the technology is being operated since August 2012. The 22MTPD (metric tons per day) plant, or 7700 tons per annum CO2 capture plant, , is owned by Solvay Chemicals and is located in India.

The CDRMax® solvent enabled capture of CO2 from a slipstream of flue gas for over 2500 hours, far more than the norm for industrial testing. “The Solvay plant testing has exhibited the robustness of CCS’s technology, which requires almost no modifications to the existing setup”, remarked Prateek Bumb, the Chief Technical Officer of CCS. The flue gas, which originates from a kiln source, contains impurities like high SOx content, NOx (upto 45ppm), particulate matter and high oxygen content. Compared to other technologies previously being used, the CDRMax® solvent required over 10 times less make-up solvent replenishment, consumed 7 times less water, and resulted in increased solvent life by 3 times, leading to savings of $23 per ton of CO2 captured. “The main advantages are lower specific energy consumption by about 30% compared to conventional technology and high O2 tolerance level” said Mr. Tirthankar Mitra, MD Solvay Vishnu Barium.

Tremendous research has gone into post-combustion carbon capture technology as it presents the most seamless and cost-effective way to reduce emissions from existing installations, especially given global governmental push towards stringent regulations. CCS has been at the forefront of technological innovation in chemical solvents for post combustion capture and has secured grants from the UK government and the World Bank (in conjunction with research partner ICT Mumbai). The CCS technology can be retro-fitted to existing installations, and has been independently evaluated by third parties such as TNO as among the best in the market currently.

“The commercial validation has supplied a wealth of data and proof that the technology can be easily scaled up 10-20 times to be fitted into 200-400 MTPD plants. The consistent capture of CO2 from the rapidly changing input gas showcases the technology’s utility in a variety of applications, ranging from industries which require CO2 as input for downstream processes, to power plants which want to reduce emissions and even in biogas up-gradation into natural gas”, said Chief Executive Officer, Aniruddha Sharma.
