Compressor Anti-surge Control

Overview

  • Effeciently controls the inlet valve and blow-off valve when the compressor starts and stops.
  • During steady operation, controls the inlet valve so that the amount of discharged compressed air becomes constant (flow control)
  • Surging: Load decreases, the amount of discharge flow and pressure drop, and a limit is exceeded, possibly destroying the compressor.

In such cases, the YS1700 Single-loop Controller switches smoothly and automatically between flow control and pressure control to prevent surging.

* A compressor is an important device in every kind of factory that is used to compress air, oxygen, hydrogen, and other source gases and process gases.

Compressor Antisurge Control

  • Selector Control (YS Specific Algorithm)
    Allows for automatic switching between two differing control factors, flow volume and pressure.
  • High Speed Control Interval (50 msec)
    Keeps up with fast process changes, enables smooth switching control.
  • User Programming
    Enables start-stop sequences and can be customized in various ways for compressors.

Industries

  • Chemical

    Chemical plants rely on continuous and batch production processes, each posing different requirements for a control system. A continuous process calls for a robust and stable control system that will not fail and cause the shutdown of a production line, whereas the emphasis with a batch process is on having a control system that allows great flexibility in making adjustments to formulas, procedures, and the like. Both kinds of systems need to be managed in available quality history of product, and to be able to execute non-routine operations. With its extensive product portfolio, experienced systems engineers, and global sales and service network, Yokogawa has a solution for every plant process.
