Design of an intelligent system to control the technological system of ammonia production secondary condensation

This paper has analyzed the functioning conditions for technological system of secondary condensation (TSSC) in a typical ammonia synthesis unit AM-1360 series with use system-control approach. The coordinates control vectors and external disturbances have been determined. An algorithm developed predicting vector subsystem decision support under such complex inertial object high metal consumption as TSSC. method mathematical modeling was used to determine, based on algorithm, patterns quantitative dependences influence temperature primary flow rate circulation gas efficiency TSSC heat exchange processes. regularity increase flows an established. parametric sensitivity change determined, which, compared rate, exceeds it by more than six times. executed software implementation employing MATLAB programming environment makes possible, owing embedded client part (ORC client), free access current data process. functional structure computer-integrated technology proposed correction supervisory mode designed. Correction solutions involving additional hardware programmable logic controller VIPA SCADA-system Zenon practically implemented. ensures stabilization at regulatory level −5 °C, which reduces natural almost 1 million nm3 per year.
