Antisurge Control System

ModAE’s Antisurge Control Systems are designed to protect compressors from dangerous surge conditions that can cause severe damage to turbomachinery.

Overview

ModAE’s Antisurge Control Systems are designed to protect compressors from dangerous surge conditions that can cause severe damage to turbomachinery. By continuously monitoring the compressor’s operating point and modulating a recycle or blow-off valve, these systems maintain stable operations while preventing surges and ensuring the compressor stays within safe operating limits.

Key Features

  • Surge Detection and Prevention
    Utilizes advanced algorithms to calculate the distance between the operating point and the surge limit, automatically adjusting valves to maintain stability. This ensures the compressor does not reach surge conditions, minimizing the risk of equipment damage.
  • Precise Control with Reduced Margins
    Integrates closed and open-loop control responses to provide precise control without requiring large control margins, thereby minimizing unnecessary recycling and maximizing efficiency.
  • Adaptable Configurations
    Designed to handle a wide range of compressor applications, from single-stage to multi-section compressors, and adaptable to varying process conditions, including changes in molecular weight and compressor geometry.
  • Coordinated Control
    Supports integration with performance control systems to optimize overall compressor operation, allowing for coordinated load sharing and balancing across multiple compressors operating in parallel.

Applications

Suitable for centrifugal and axial compressors used in various industries such as power generation, petrochemicals, and oil & gas, ensuring safe and efficient compressor operation.

Benefits

  • Prevents costly damage to compressors by keeping operations within safe limits.
  • Enhances system stability and reliability, reducing unplanned shutdowns.
  • Minimizes process disruptions with smooth and automated valve control.
  • Supports flexible configurations for diverse compressor applications.
