Abstract

The bioenergy with CO2 capture and storage (BECCS) is a promising solution to cut CO2 emissions and will play an important role in achieving the climate goal of 1.5°C. As the properties of biomass varies significantly, it is of importance to understand the dynamic performance when capturing CO2 from biomass fired power plants.This work is to reveal the dynamic performance of chemical absorption. The aqueous solution of monoethanolamine (MEA) was selected as the solution. By using the real flue gas (FG) data , the influence of FG flow rate on CO2 capture were studied by doing dynamic simulations. It has been found that as the FG flow rate decreases, the CO2 capture rate first rose before going down; and the reboiler duty decreased while the energy consumption of CO2 capture increased.
