Method for absorption of atmospheric carbon dioxide in compensation of carbon dioxide emitted by e.g. thermal power plant, involves forming sodium carbonate solution, and retreating sodium carbonate solution and hydrochloric acid solution

摘要

The method involves performing dissociation of a saline aqueous solution i.e. sodium chloride saturated brine, based on reaction of membrane electro dialysis to separately produce de-salted water, a soda solution and a hydrochloric acid solution, where electric energy required for the reaction of membrane electro dialysis is obtained from production sources e.g. photovoltaic, wind, nuclear source. Atmospheric carbon dioxide is captured by the soda solution, and a sodium carbonate solution is formed. The sodium carbonate solution and the hydrochloric acid solution are retreated.
