Abstract: A comparator has a hysteresis value which is adjustable in response to a hysteresis setting control signal. An input of the comparator receives a modulated signal contaminated by in-band noise. A pulsed signal output from the comparator is converted by a digital to analog converter circuit an analog signal. That analog signal is converted by an analog to digital converter to a digital signal value. A comparison circuit compares the digital signal value to a threshold value and generates the hysteresis setting control signal to adjust the hysteresis value of the comparator in response to a result of the comparison in order to suppress the in-band noise from the output of the pulsed signal output from the comparator.

Abstract: The present disclosure proposes a flue gas purification and CO2 capture coupling system and a carbon capture method. The flue gas purification and CO2 capture coupling system comprises a flue gas generation device, a flue gas purification device, and a CO2 capture device. The CO2 capture device comprises an absorption tower containing an absorbent solution and a regeneration tower. A rich absorbent solution that has absorbed CO2 in the absorption tower flows into the regeneration tower where it is heated and desorbed into a regenerated gas and a lean solution. A portion of the lean solution discharged from the regeneration tower is used to exchange heat with high-temperature flue gas that has left the flue gas generation device but has not yet entered the CO2 capture device, thereby forming a superheated lean solution. The superheated lean solution is returned to the regeneration tower to provide steam and heat for the CO2 regeneration reaction.
