Automated Control System of Experimental-Industrial Unit of Gas Condensate Stabilization

Description of technological object

Object of automation is process unit of experimental-industrial installation of gas condensate stabilization with located on its territory following technological facilities:

  • rectifying columns;
  • evaporator;
  • condensate tanks;
  • separator;
  • pipeline system with actuator valves and cutoff valves.

Destination of the ACS

The system is intended for managing the technological objects of the installation of gas condensate stabilization in accordance with operating standards of quality and provides automated control and monitoring of process objects, primary (main) and secondary (auxiliary) equipment, rational running of equipment and technical diagnostics of its state.

Structure and functions of the ACS

The developed system is integrated automated system that is based on present-day universal automation system SIMATIC C7 from SIEMENS and operator workstation, which both perform the functions of measurement, monitoring, automatic control, visualization and archiving of events and parameters of technological process.

Structure chart of the automated control system is shown on figure 1.

Result of application of the system

  • information acquisition and centralized control, operative representation of information about technological process flow and state of equipment;
  • automatic continuous monitoring of state of health of basic facilities and devices;
  • program-logical control (blocking) for automatic protection of equipment in accordance with technological schedule;
  • notification of the personnel about abnormal modes of working (technological signaling, alarm visual and alarm sound signaling in the case of irregularity of technological parameters);
  • execution of safety actions;
  • execution of procedures on data exchange with upper level of management in real time or on request.

Result of application of the system

Systems implementation permits:

  • to increase personnel safety, equipment safety and environmental protection;
  • to increase the efficiency of operation of technological equipment;
  • to increase the efficiency of maintenance of technological process;
  • to improve technical and economic indices;
  • to decrease in-process loss;
  • to save energy and operating resources;
  • to increase quality of production;
  • to prevent emergency situations in advance and localize faults opportunely;
  • to decrease technical servicing and remedial maintenance burden.
