description: The aim of this work is to develop an automation system for the cryogenic heat exchanger to enhance the efficiency of the technological process and minimize technological risks. The tasks addressed during the research include the following: 1) studying the technological process of natural gas liquefaction; 2) investigating the requirements and regulatory framework for the development of automation systems; 3) analyzing the technological parameters to be subject to automatic control and signaling; 4) developing the lower, middle, and upper levels of the automation system; 5) selecting technical means for implementing the automation system; 6) choosing automation tools; 7) calculating the technical means for the automated control system of the technological process; 8) developing the functional diagram of automation. During the analysis of the technological process and based on regulatory documentation, technological parameters subject to automatic control and signaling were described, the structure of the cryogenic heat exchange process system for liquefied natural gas production was outlined, as well as the functional purpose of individual components. The calculation of the technical means of the automated system was performed, a functional diagram of automation was compiled and described, an algorithm flowchart for controlling valves was developed and described, and the quantity and types of signals from sensors and actuators were counted.
