Oil Refinery Controls Upgrade

Posted on December 30, 2005

GE Energy announced that it recently completed a retrofit of the turbine-compressor control and protection systems at Rompetrol’s Petromidia Refining Complex near Constanta, Romania.

The project, which was completed this month, replaced older mechanical controls for the plant’s steam-turbine-driven hydrogen gas, main air, and wet gas compressor trains with GE’s Integrated Turbine Compressor Control (ITCC) solution. The ITCC incorporates triple modular redundancy and advanced control algorithms, allowing critical compressor trains to boost operational margins while enhancing the refinery’s process reliability. Project scope also included turbine speed control, auxiliary system control, overspeed protection, mechanical actuation, new anti-surge valves, and numerous hydraulic components including sensors, actuators, and power units.

Because a particularly important facet of the project was to improve compressor operation, GE mapped the compressors’ performance and then created custom algorithms. These algorithms enable Rompetrol to take full advantage of the compressors’ flow capabilities, while maintaining process stability and limiting the cost impact of unnecessary recycle valve operation.
