Prof. Guomin Cui is a researcher working for more than 20 years in the fields of power engineering and engineering thermodynamics at School of Energy and Power Engineering, University of Shanghai for Science and Technology. His particular focus lies on the heat transfer enhancement, process system optimization and energy-saving technologies, and new energy system integration. Based on rich research and work experience on heat and mass integration of process system, he deeply understands the nature of process system integration and has made positive progress in the design of heat and mass exchanger networks. The chessboard model, node-wise non-structural model, continuous non-structural model and its extended structures were established and widely used to optimize the heat and mass exchange network and get better results. In terms of algorithms, the random walk algorithm with compulsive evolution was developed, and on this basis, strategies such as fine search, random perturbation, fixed investment relaxation, delayed evolution, structural evolution enhancement, and optimization routes were gradually established. The synchronous development and cooperation of the model and algorithm greatly improved the global optimization level of the heat and mass exchange network. He has presided over more than 20 national, provincial and ministerial projects including three National Natural Science Foundation projects, and published more than 200 scientific research papers.

Summary
As the concept of green low-carbon development and the goal of "carbon peak" and "carbon neutral" driving, the call for energy saving and emission reduction in the process industry continues to rise. Heat exchanger network integration technology is an important means to enhance energy efficiency and carbon reduction, while mass exchanger network integration technology can effectively improve the product process and reduce pollution emissions. Hence research and application of the two become a hotspot in chemical engineering, system science and environmental engineering, achieving both economic energy and emission. At present, the integrated technology for heat exchanger network and mass exchanger network has held a high ground but is imperfect, in which the research characteristics, application targets, and bottlenecks encountered are not similar. Therefore, it is the focus of this special issue to reveal the nature of the optimization problem of heat and mass exchanger network synthesis, to break through the current dilemmas and bottlenecks, and to analyze the future research directions and priorities.
Topics of interest include but are not limited to:
1) Review of the research status in system heat integration.
2) Modeling and optimization of heat and mass exchanger networks or other process systems.
3) The application of pinch technology and the combination of that with other optimization techniques.
4) Strategies for solving the optimization stagnation, the trap of local optima, and structural clusters during the process integration of complex heat and mass transfer systems.
