Experimental and Numerical Characterization of a New Structured Packing for CO2 Capture
Structured packings with a low pressure drop can reduce the energy consumption of CO2 capture plants. In this work, an experimental and a numerical study of a new structured packing with an inclination angle of 75 degrees were carried out. The packing performance was compared to that of a state-of-the-art packing with an inclination angle of 45 degrees. Experimental results revealed that the specific pressure drop can be reduced by over 90%, whereas for the separation efficiency, only a small reduction was found. Simulations were conducted for industrial-scale flue-gas conditions of a gas-fired and a coal-fired power plant. For the coal-fired power plant, only a slight reduction of the separation efficiency was found, while for the gas-fired power plant, there was even no reduction. Thus, both experimental and simulation results revealed a high potential of the new packing, which appears to be a good alternative to conventional packings in CO2 capture applications.
