Flue gas would go through the towers.

烟道气会通过这些塔。

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.

徐说，与其他情况下的碳捕获不同，烟道气中的二氧化碳浓度通常在15%或以下。他补充说，研究团队已经完成了1000多项测试，以找到合适的吸收剂。

Energy players at home and abroad have been expanding their presence to tap the potential of the CCUS sector－a set of methods and technologies for removing carbon dioxide from flue gas and the atmosphere, recycling it for use, and establishing safe and long-term storage modalities.

"Li Qilin, executive chairman of the chamber and president of Beijing SPC Environment Protection Tech Co Ltd, a company specializing in industrial flue gas desulfurization, denitrification and dedusting, said new growth momentum has been injected into the environmental protection industry.

After more than 20 years of research, Gao and his team developed an ultra-low-emissions system to filter multiple pollutants from coal-fired flue gas quickly and cheaply.

The tech firm is a sector leader in industrial flue gas desulfurization, denitrification and dust removal.

"We will keep promoting flue gas control of the thermal power industry, and expand our business into other industries, such as iron and steel, cement and petrochemistry," Li added.
