摘要：The article studies the question of improvement of environmental performance of chemical and technological production of ammonia by automating the process of absorption of ammonia from purge gases. The basic principles of the automation process of absorption of ammonia and selected means of automation were determined, taking into account the characteristics of the technological mode. The functional scheme of the automation and the system of automated control of absorption of ammonia in the production of fixed nitrogen were developed. The designing of control system by consistent definition of principles, parameters and technical means of the automation was performed. The computer simulation of absorption in the software package Honeywell Experion Process Knowledge System was carried out. The process control strategy was developed on the basis of the microprocessor C200 Honeywell using software package Experion PKS. The computer simulation provided the results, which show the system response to change of input parameters. The circuit of emergency shutdown and clipping of the system from input parameters was developed.
