As its fourth and largest carbon capture project ever, China Energy has made substantial upgrades to its CO2 capture and compressing technologies, largely reducing second-time energy consumption and cutting absorbent costs.
"It is not an easy process as we want to find an amine absorbent that is energy-efficient, highly stable and endurable," said Xu Dong, director of the carbon neutrality center of the Guodian Institute of New Energy Technology, which is affiliated with China Energy.
Unlike carbon capturing in other scenarios, the concentration of CO2 from the flue gas is usually at or below 15 percent, Xu said, adding that the research team has completed more than 1,000 tests to find a suitable absorbent.
Its wide assortment includes all kinds of face masks, antimicrobial gloves and isolation gowns, but also many absorbent products like incontinence care and wound-care products.
As a processing enterprise, we use our research and development ability and advanced technologies to add value to bird's nest, making it more absorbent and more tasty," Shan said.
