A chemical plant in India has become first in the world to run a new system for capturing carbon emissions and converting them into baking soda. The Tuticorin Alkali Chemicals plant, in the industrial port city of Tuticorin, is expecting to convert some 60,000 tonnes of CO2emissions annually into baking soda and other chemicals – and the scientists behind the process say the technique could be used to ultimately capture and transform up to 10 percent of global emissions from coal. The researchers have developed a profitable, practical system that could have the commercial potential to expand to other plants and industries. In the Tuticorin setup, the plant runs a coal-fired burner to make steam that powers its various chemical-manufacturing processes. A mist containing Carbon Clean’s chemical separates the CO2 emissions in the burner’s chimney, which are then fed into a mixing chamber with salt and ammonia. The end product can then be used to produce baking soda (sodium bicarbonate) or a range of other compounds, for use in things such as glass manufacture, detergents, disinfectants, and sweeteners. The new type of filtering chemical is more efficient than the amine compounds that scientists have previously used, and requires less energy to run, say researchers.
