CPC Antisurge Controller
The integrated controls enable to efficiently protect the compressor and to ensure maximum process availability as well as the highest achievable efficiency.
The supporting hardware controller, that can be adapted to fit all applications, is:
- A stand-alone micro-processor based system (Protronic P700)
- A compact PLC (SIEMENS, Allen-Bradley, Shcneider…)
CPC Antisurge Controller - ASC
The ASC is the controller in charge of ensuring a minimum flow rate in the compressor, thus avoiding the phenomenon of surge through the opening of the Antisurge valve.
For this purpose, parameterised safety margins are set based on the surge flow rate for each application.
CPC Surge Detector - SD
As a general rule, the Antisurge control will rapidly prevent/interrupt surging of the compressor, owing to its highly dynamic features.
However, if the process upset happens again, multiple surges will occur with a requirement to interrupt a series of repeated surges.
The CPC Surge Detector fulfills this purpose: it continuously monitors a compressor parameter that is significantly affected by surge, gives an alarm when surge is first detected, eventually allowing production personnel to intervene and stabilize the operation of the compressor, and ultimately stops the compressor when multiple surge occurrences are detected.
CPC Process Controller - PRC
The Integration of the compressor into its surrounding process is a key element of CPC Engineering compressor protection solutions. The CPC Performance Controller (PRC) permits addressing the most complex process control challenges, therefore enhancing process operation.
The CPC Performance Controller works hand in hand with the CPC AntiSurge controller to optimally protect both compressor and process where it is operating.
The process parameters that can be optimised via the PRC are the compressor load, motor power, suction and discharge pressures and temperatures.
