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.
