Annotation:

The authors of the article developed the Markov models for analyzing the efficiency of automated control systems for the complex gas treatment units (ACS CGTU) functioning. The problem of mathematical and program packages insufficiency for ACS CGTU, dedicated to the effectiveness estimation and optimization of gas processing technology type, is marked. Three gas processing technology types based on the low temperature separation are considered. The grounds for developing the evaluation models of optimality criteria for gas preparation process are defined. A multi-criteria model for the estimation and selection of the optimal gas processing technology is implemented. The recommendations on the accounting for the probability of the operational state of the complex gas treatment unit components, when using the economic criteria to evaluate the gas preparation technology implementation in conditions of low-temperature modes are presented. Technological and economic indicators were compared to choose the rational gas processing technology. The results of multi-criteria evaluation revealed the advantages of the low-temperature method application with choking. The software implementation of the computing module for the multi-criteria selection and gas processing technology optimization is proposed.
