Title:
FLUE GAS LOW-TEMPERATURE ADSORPTION DENITRATION METHOD
Document Type and Number:
WIPO Patent Application WO/2021/082308
Kind Code:
A1
Abstract:
Disclosed is a flue gas low-temperature adsorption denitration method. The method comprises: pressurizing flue gas subjected to dust removal and desulfurization; pre-cooling the pressurized flue gas; cooling the pre-cooled flue gas to below room temperature by using a flue gas cooling system (1); feeding the flue gas, the temperature of which is lower than room temperature, into a low-temperature denitration system (2); carrying out physical adsorption denitration in the low-temperature denitration system (2); pre-cooling flue gas subjected to dust removal and desulfurization by using the denitrated flue gas; and feeding flue gas, which has absorbed heat, into a chimney for discharging.
