Process gas compressors are often running in parallel. Next to demands for optimum efficiency this requires all compressors operating at the same distance from the control line. If a single compressor is operating with partially opened blow-off control valve it will significantly affect efficiency and may seriously disturb the gas flow.
Experienced operating personnel used to avoid critical operating conditions by manually setting each compressor to stable setpoints. Increasing process automation now requires intelligent load-sharing algorithms.
GEBHARDT Automation has more than 15 years of experience with load-sharing applications. The sturdy control algorithm guarantees good performance and simplifies commissioning.
