With the continuous development of social economy and science and technology, the production scale of air separation equipment is getting larger. As an important part of the whole air separation equipment, automatic control system develops from the original instrument control system to PLC automatic control system, then develops to the DCS, CCS, SLS and AMS control systems which widely used nowadays. With the improvement of social awareness of energy and environmental protection, the advanced control system is used to realize the optimization of air separation equipment, and the control technology of automatic load changing to realize energy saving and consumption reduction is also emerged.
