Compressor Control System
YOUR
CHALLENGES
CHANCES
Instead of being associated with the process, compressor control schemes in the process industry only protect compressors, and unit control is done manually. When there are large fluctuations in the process or unstable conditions during the start-up, manual operation may lead to process instability or even shutdown.
Based on anti-surge, speed regulation, performance control and other control policies, the compressor control solution of SUPCON and its products realize safety protection, auto start or shutdown and automatic control of compressors.
Features Overview
 Load distribution of multiple units
Load distribution of multiple units
Abandon the conventional equal-flow parallel, flow pressure cascade control and other methods, adopt the control mode of equal-distance control of parallel units, and coordinate the action of the compressor through network connection, greatly improving the working efficiency of the compressor.
 Performance control
Performance control
This is process-oriented performance control, coordinated with multi-loop optimization control, and achieve the decoupling between performance control and surge control.
Steam turbine control
Steam turbine control
The scheme uses a special fast PID algorithm to adjust the speed of steam turbine to achieve efficient and safe control of steam turbine.
 Surge control
Surge control
Through multi-parameter dynamic calculation, dynamic control and adjustment can be realized at the same time of protection, so as to achieve more accurate control and smaller safety margin.
Your Benefit from supCCS
Compressor station of long distance natural gas pipeline
supCCS can realize remote monitoring of ventilation, motor cooling, fire and gas system, power distribution and supply system of compressor unit and auxiliary workshop. It can also realize high efficiency anti-surge control, performance control and load balance control of parallel compressor unit.
Air compressor for large air separation unit
The decoupling algorithm of dynamic outlet pressure control and surge control brought by supCCS solution can effectively improve the operation stability of the supercharger.
Refrigerating compressor
Refrigeration compressors are used in the olefin, coal chemical, LNG and chemical fertilizer industries.supCCS can well solve the problem of mutual interference and cold & heat balance between the cooling rate control, temperature control and surge control, and greatly reduce the fluctuation in the operation of equipment
Gas cracking compressor for ethylene plant
Crack gas compressors are essential for the smooth operation of ethylene plants. The supCCS solution provides performance control that allows the inlet pressure to operate close to the downline, and the interval pressure and outlet pressure to operate close to the upper limit while maintaining a stable control of the inlet pressure.
Continuous reforming of the new hydrogen supercharger
Reforming reaction pressure is an important parameter in the whole process and is easily affected by external temperature and other factors. supCCS uses two control loops to control the compressor speed and the inlet discharge torch valve respectively. Through precise loop control, the anti-surge valve can be all closed, reducing energy consumption
Refining catalytic cracking unit compressor
In the catalytic unit, the flow rate of the main fan and the inlet pressure of the rich gas compressor are the key process variables. supCCS can automatically control the inlet pressure of the guide vane of the main fan and the rich gas compressor as well as the inlet discharge valve, so as to stabilize the compressor and process operation, avoid unnecessary shutdown, and improve the quality of oil
