ANALYSIS OF TECHNOLOGICAL PROCESS OF PRODUCTION UREA AS CONTROL OBJECT
This paper provides a detailed description of the technological scheme of production urea, the stage of the syn-thesis and distillation. The main reactionary ratios of production process are given. Considered are ways of maintenance of technological parameters in each device at the set level. Analyzed influence of quantitative change initial components on a course of process, allowing to prove the need to maintain an optimal molar ratio of the components and to identify the main task of the study. In connection with this process was taken as the control object identified basic input and output parameters and also marked the basic disturbing factors related to the chemical-physical characteristics of the production process. Presented is the block diagram of the control stage of the synthesis of urea. Asked to implement the management on the basis of a mathematical model.
