Numerical Study on Flow Field Distribution Regularities in Wet Gas Desulfurization Tower Changing Inlet Gas/Liquid Feature Parameters

Qingbo Deng et al.

Summary: In the wet gas desulphurization tower, the uneven distribution of flue gas can be counteracted by increasing the amount of slurry spray and integrating the flow field. Lowering the inlet velocity helps improve flow field uniformity and reduces energy and material consumption.

Wet flue gas desulfurization performance of 330 MW coal-fired power unit based on computational fluid dynamics region identification of flow pattern and transfer process

Jiangyuan Qu et al.

Summary: This study investigates the desulfurization performance of a wet flue gas desulfurization unit based on spray scrubber using CFD method in an Eulerian-Lagrangian framework. The research reveals that the uniformity of flue gas in the scrubber is largely determined by the force-balanced droplets in the middle part of the scrubber. The momentum transfer behavior and SO2 chemical absorption process exhibit synchronicity with the evolution of gas-slurry flow pattern, while heat transfer has little effect on the overall absorption process.

Mass transfer process intensification for SO2absorption in a commercial-scale wet flue gas desulfurization scrubber

Jiangyuan Qu et al.

Summary: The study shows that the SO2 absorption process in a Spray Scrubber is significantly influenced by spray behavior, including parameters such as droplet diameter, injection direction, and spray morphology, which have a significant impact on desulfurization performance. Proper selection of droplet diameter and injection method can effectively enhance the SO2 absorption process and improve desulfurization efficiency.

Modeling and analysis of CO2 capture by aqueous ammonia plus piperazine blended solution in a spray column

Yin Xu et al.

Summary: Chemical scrubbing using NH3/PZ solution is a promising method for reducing CO2 emissions from fossil-fuel combustion. An advanced model was developed to predict CO2 absorption using a blended solvent in a spray column, which was verified by experimental results. The study revealed important characteristics of the scrubbing process, including gas-phase back-mixing behavior and the energy analysis of heat release during CO2 absorption.
