TECHNOLOGICAL COMPLEX OF SECONDARY CONDENSATION OF AMMONIA PRODUCTIONS AS AN OBJECT OF SYSTEM ANALYSIS

Abstract

The features of the hardware and technological design of the technological complex of secondary condensation (TCSC) operating in Ukraine units for the synthesis of ammonia of the AM-1360 series have been established. The disadvantage of such units is the excessive consumption of electricity as a result of the use of an electrically driven turbocharger refrigeration unit. The direction of the study of TCSC as a technical system is determined from the standpoint of system analysis. Its advantages in solving inventive problems are determined. The technical system is considered element by element. The main control tasks that the TCSC operator performs are defined. The conclusion is made about the dependence of any technical system, which necessitates the presentation of TCSC as a subsystem in relation to the anthropometric system. Useful, maintenance and harmful functions of TCSC are isolated and analyzed. Their definition and belonging is due to certain properties of the elements of the technical system, which are provided by the main useful function. It is shown that the main useful function is derived from the needs of the operator. Therefore, the anthropometric system in relation to the technical system is a supersystem. The analysis of TCSC made it possible to establish administrative, technical and physical contradictions in accordance with the main useful function – increasing the energy efficiency of TCSC. A systematic approach was applied to perform a goal-oriented system of actions using such terms as visual situation, goal, goal achievement operators, resources, by-products (phenomena). The improvement operator (Q-innovation) of the technical system and "free" resources (R-innovation) for the implementation of the goal operator are determined. This made it possible to synthesize a new TCSC technical system, the increase in energy efficiency (i.e., the performance of the main useful function) of which is ensured by a reduction in electricity consumption by 3.6 thousand kWh even when the ambient air temperature rises above 30 °C.
