Compressor unit automation

A compressor control system connects controllers, operator workstations, sensors and actuators. It executes agreed control algorithms and shows the operator the condition of the compressor and its auxiliary equipment.

Turboserv designs compressor control systems, develops PLC and SCADA application software and takes part in commissioning. The scope depends on the process, manufacturer documentation and the existing system.

Algorithms, interlocks and operator workstations

  • Step-by-step compressor start-up and shutdown programs
  • Automatic loading and unloading according to agreed algorithms
  • Interlocks, protections and equipment diagnostics
  • Oil system and auxiliary equipment monitoring
  • SCADA screens, trends, alarms and event logs
  • Data exchange with monitoring and supervisory systems

Experience with nitrogen and oxygen compressors

We designed control systems for a 19,000 Nm³/h nitrogen compressor and a 12,500 Nm³/h oxygen compressor. We developed application software on Siemens S7-400H and SIMATIC PCS 7 and took part in commissioning. Both units are in operation.

Anti-surge control for these compressors is supplied by the manufacturer. Software development takes account of equipment documentation and the suppliers’ responsibilities.

Adapting equipment from Chinese manufacturers

We adapt automation systems for equipment from Chinese manufacturers to customer and site requirements. We work with manufacturer documentation and agree signal lists, control algorithms and data interfaces.

Application software development and commissioning take account of the equipment’s own protection systems and the agreed allocation of responsibilities.

How we work

  1. Initial data

    Review the compressor process, manufacturer documentation, signal list and control system requirements.

  2. Design

    Agree the system architecture, control algorithms, interlocks and equipment interfaces.

  3. Software development

    Program controllers and operator workstations and test software and screens before site work.

  4. Commissioning

    Take part in signal checks, algorithm adjustment and system commissioning within the agreed scope.

FAQ

Which compressors have you developed control systems for?

Our portfolio includes nitrogen and oxygen compressor control systems. For a new unit we review the process and manufacturer documentation before agreeing the design, software development and commissioning scope.

Can we commission only PLC and SCADA programming?

Yes. Application software can be developed from an existing design and equipment documentation. The software, algorithms and operator screens are agreed before work starts.

How is compressor automation priced?

Cost is assessed from the signal and workstation counts, platform, algorithms, documentation and the required design and commissioning work. Send a description of the unit and the task for an estimate.
