Because my country is a big country in energy consumption, especially the one-time energy structure dominated by coal. Fuels combustion releases carbon dioxide into the atmosphere, and the buildup of CO2 can lead to global warming, regional climate change, and acidification of seawater. Carbon dioxide capture, utilization and storage have become the main direction of greenhouse gas emission reduction, and it is a major demand for my country's ecological environment protection and social and economic development.
Since 2007, under the leadership of Academician Fei Weiyang and Director Luo Guangsheng, the research groups of Chen Jian and Tang Zhigang have successively completed the National 863 Key Project, the National Natural Science Foundation of China Key Fund, the National Support Program Project, the PetroChina Low-Carbon Key Technology Research Major Science and Technology Project, etc., and won the first prize in science and technology of China coal industry association in 2018. The discipline direction with independent technology characteristics has been formed initially. The laboratory now has complete pre-combustion capture and post-combustion capture basic experiments, simulation calculation software and full-process test devices, including solubility, reaction rate, reaction heat, solvent degradation, mass transfer of filler, CO2 absorption and capture before combustion- Membrane desorption device, potassium carbonate CO2 capture membrane analysis device, membrane coupling electric field enhanced CO2 capture and separation device from the atmosphere, post-combustion CO2 absorption and capture device, and corresponding basic calculation and process simulation optimization software.
Development of new mass transfer small crest angle packing: According to the CFD simulation and experimental results, the defects of the traditional corrugated structure were analyzed, and a new small crest angle corrugated packing was developed to overcome the non-ideality of the gas-liquid two-phase flow of the traditional corrugated packing , which can greatly improve its performance. The main feature of this packing is that the tip angle of the packing is reduced from about 90 degrees to about 30 degrees. CFD simulations show that the new type of corrugated packing with small apex angle can not only suppress the liquid phase drift, greatly increase the coverage area of the liquid phase on the packing surface, but also reduce the cross gas flow ratio η, reduce the pressure drop, and increase the flux.
