Chemical system engineering  is an emerging marginal subject that applies the theory and methods of system engineering to the field of chemical processes, and is a branch of chemical engineering. Its basic content is: from the overall goal of the system, according to the characteristics of the internal components of the system and their interrelationships, determine the optimal strategy of the chemical system in planning, design, control, and management. The mathematical tools used are some methods of operations research and modern cybernetics, and the technical means that they rely on are electronic computers.
The research object of chemical system engineering is a certain system in the process of chemical production, and the goal is to optimize the system as a whole, that is, to reasonably determine and control the input and output states of each component of the system, so that a certain quantitative function reflecting the benefits of the system is achieved The maximum or minimum value. This function that reflects the overall goal of the system is called the objective function. For example, when carrying out the optimal design of a chemical plant, investment costs and operating costs are usually selected as objective functions in order to find a design solution with the lowest total cost. Chemical system engineering is a developing discipline. So far, people have different understandings and definitions of this discipline.
Chemical systems, like all systems, have a nesting feature, that is, a system is always a part of another larger system and is a subsystem of the larger system; at the same time, it may be controlled by smaller subsystems Make up. The unit operation and reaction process are generally regarded as the basic elements of a chemical system, and the system can be regarded as a network of a series of basic elements in a certain connection manner. Therefore, the characteristics of the chemical system can be attributed to the characteristics of the basic elements and the characteristics of the system structure.
