Abstract: The work considers the issues of automating the technological process at a stationary nitrogen compressor station of a modular type, oriented for using in the oil and gas industry. The focus is on designing and modelling a closed-loop control system for regulating the pressure of technical nitrogen at the outlet of the booster compressor. The work jus-tifies the choice of parameters to be controlled, analyses automation technical means (sensors, PLCs, actuators), and constructs an information model of the control object. The authors apply a mathematical model of the object in the form of a first-order inertial link with delay; implement the control algorithm in Python using a PI controller; con-struct graphs of transient processes based on the modelling results, confirming the system stability and the regulation accuracy. The paper demonstrates the necessity of transitioning to modern domestic technical and software solutions in production and educational processes; compiles a block diagram of the air dryer control algorithm, which is im-plemented in the Codesys 3.5 programming environment. It is concluded that the developed approach can be applied as part of SCADA systems and adapted to industrial conditions. The proposed methodology can be used for educa-tional and design purposes to optimize control systems for compressor units in gas separation installations.
