HiGee Chemical Separation Engineering

Youzhi Liu is professor of North University of China, doctoral supervisor, director of the Shanxi Province Key Laboratory of Higee-Oriented Chemical Engineering, the first Fellow of China Chemical Industry Association, enjoying the Special allowance of The State Council. He is the executive Deputy Director of the Chemical Process Intensification Committee of the China Chemical Industry Association, the Deputy director of the Chemical Engineering Teaching Steering Committee of the Ministry of education of the people's Republic of China and an expert in evaluating the level of Undergraduate Teaching. He also serves as the deputy editor-in-chief of “Chemical Progress”, deputy director and executive deputy director of the book named “Key Technologies for Chemical Process Intensification series”. He has been engaged in the research of chemical process intensification theory, the foundation of HiGee chemical process and applied technology for more than 20 years. Under the guidance of the operation of the HiGee chemical unit, the new intensification mechanism of the separation process of the HiGee chemical industry is comprehensively innovated, and the application field is innovated and expanded. Based on the collaborative innovation of device technology and separation process, the common key technologies of engineering are conquered, and the complete set of engineering equipment and technology of HiGee separation are formed. He was responsible for drafting the industry standard of “High gravity device”, authorized 98 invention patents, published more than 400 academic papers, and published works including “Chemical Process Intensification Methods and Technologies”, “Chemical Engineering Process and Technology in High Gravity” and so on. A number of scientific research achievements have reached the international advanced level, and have been successfully applied in chemical industry, energy, environmental protection and some other fields, achieving significant economic and environmental benefits, and promoting the technological progress of the industry.
