INVESTIGATION OF THE PROBLEMS OF INTELLIGENT CONTROL OF THE PROCESS OF LOW-TEMPERATURE SEPARATION OF NATURAL GAS.

This article analyzes the problems of intelligent control of the process of low-temperature separation (LTS) of natural gas and modern approaches to solving them. Since the process complexity of gas separation at low temperature as well as multidimensional technological parameters have nonlinear control properties, a principled technological scheme for intellectual control of technological parameters such as gas humidity, temperature, pressure, consumption and diethylenglicol (DEG) consumption of the LTS process has been developed. The analysis and literature review show that intellectual control methods allow for stable operation of the technological process, reduced energy consumption, reduced heat exchange, and reduced gas hydrate formation in low-temperature separation devices. This study presents the conclusions obtained from the implementation of adaptive and intelligent control systems in low-temperature gas separation processes, as well as the existing scientific problems.
