A general computer program for modeling the dynamic behaviour of complex plants is described. Given the name DYNSYS, this program permits computation modules to be written for the various plant units, incorporating the differential equations describing their dynamic behaviour, then uses an Adams‐Moulton‐Shell integrating procedure. Process lags are also handled by the system. Computation modules for control devices, such as a standard three mode controller, can be incorporated into the system. The program has been operated in both a batchwise and interactive mode using the CDC6400 computer. The application of DYNSYS to the modeling of two chemical process units is discussed: a liquid‐liquid extraction unit for recovering butadiene in a synthetic rubber plant; and the modeling of a chlorine compressor system.
