A procedure for constructing a computer-integrated system for automating the technological process of processing associated petroleum gas has been developed. Development of the technological process according to the proposed procedure makes it possible to identify and overcome the difficulties encountered in solving the problems of technological calculation and synthesis of an automatic control system. Difficulties are exacerbated by the influence of heavy disturbances in the flow and concentration of associated petroleum gas.

Using the procedure, a technological process for processing associated petroleum gases along with an automatic control system has been developed. The technological process was adapted to use in medium oil fields, such as Ukrainian, which are characterized by low bulks and territorial dispersion. This makes it economically inexpedient to design large gas processing plants operating at a fixed load and gas concentration, which are common in the main oil-producing countries. Therefore, the technological process ensures production of methane and propane-butane of a required quality in the conditions of deviation of composition, concentration and flow rate of the streams incoming from wells in a wide range.

The automatic process control system has a two-level structure. The upper level is used to ensure operability at heavy disturbances, which is achieved by changing the operation conditions. The lower level ensures stabilization of the process for small disturbances. Two alternative implementations of the automatic control system based on PID controllers and linear quadratic regulator (LQR) were considered. The results of simulation made in HYSYS program show advantages of the cascade system of the proposed structure based on PID controllers. The control system ensures operability in conditions of deviation of gas flow by ±30 %, when the mole fraction of the gas components alters by 30–50 % and when the gas temperature deviates by ±15 °C from the values of working conditions
