1. Basic research and application of gas-liquid mass transfer methods

In chemical production, in many cases the materials handled are fluids. Mass transfer between fluids is an important and fundamental process in all reaction processes. Different from the homogeneous system, the mass transfer process at the gas-liquid interface is very complicated due to the large difference in the diffusivity of materials in the gas-liquid heterogeneous system and the complex and changeable flow field structure. However, gas-liquid two-phase interfacial mass transfer widely exists in petrochemical, biopharmaceutical, food processing, metallurgical refining, energy conservation and environmental protection and other fields, and is often encountered in basic chemical unit operations such as rectification and absorption. Therefore, it is very necessary to deeply study the mass transfer at the gas-liquid interface.

2. Clean and low-carbon industrial production process and equipment

Coking production is a highly polluting industry. In the process of coking its main product and recycling by-products, it produces a large amount of waste water and waste gas. Cleaner production is a means of controlling pollution, and it is also a new mode of production. Through rational use of raw materials, combined with the simulation process to improve production technology and equipment, improve production efficiency and raw material utilization, improve production management, and strengthen the management of the whole production process realizes the organizational form of synergy, pollution reduction and conservation, which is a new form of circular economy. I have long been committed to the development and research of comprehensive utilization of energy, promoting clean production and developing circular economy. It has developed more than 10 clean process technologies for coking production, and formed more than 50 patents, including more than 30 national invention patents, and won 1 industry association award and 2 industry association awards above the provincial and ministerial level.

3. Carbon dioxide capture technology (CCS)

Since 2010, Associate Professor Tang Zhigang has been engaged in the interdisciplinary scientific research of mass transfer separation and carbon dioxide capture under the leadership of Academician Fei Weiyang and Director Luo Guangsheng. He has successively participated in the national 863 key projects, the major scientific and technological projects of PetroChina's low-carbon key technology research, the key funds of the National Natural Science Foundation of China, the national support plan projects, and other related scientific research projects. Tang Zhigang's research group has initially formed a subject direction with independent technical characteristics, including the development of new organic solvent absorption-membrane desorption processes, as well as the new technology of hot potash-membrane separation using industrial solid waste and mineralization mechanisms to capture CO₂. He is currently the director of Beijing Carbon Neutrality Society.
