Abstract:
Amine scrubbing is the benchmark technology for carbon capture. However, amine scrubbing requires elevated-temperature steam to promote CO2 desorption. In order to solve the problem of high energy consumption, a combustion desorption reaction system (CDRS) was proposed, which integrates an electrochemical process and waste incineration process. A CDRS model was developed. Experimental study and numerical simulations on the CDRS were conducted. The effects of the initial value of concentration, the position of the anode plate, the depth of the solution, and the size of the reactor on CDRS performance were studied. It is found that electron transfer occurs during the reaction and a voltage of 0.35 V is generated. In addition, it is shown that the maximum CO2 desorption temperature in the system is 88 °C, and its average value is around 63 °C. The energy consumption is determined as 1.4 GJ/t. The CDRS increases the CO2 desorption rate by 98% at 90 °C compared to the amine scrubbing technology. ©
