CODES™ is a first principles compressor design and simulation tool for use with steady-state simulator tools like Petro-SIM®, UniSim® and HYSYS®.
CODES™ is first of its kind – compressor design rating and performance software integrated within an engineering simulator.
  • CODES™ allows an engineer to create an accurate centrifugal compressor model and predict compressor performance before any vendor data is available
  • CODES™ increases modelling accuracy in the conceptual phase by defining compressor requirements and operating envelope without the need to rely upon vendor input, input which may be limited in early phase works.
  • CODES™ ensures expensive, time-consuming rework is not required in later stages of the project

This software comes as an extension for Petro-Sim™ 6 and onwards from KBC Advanced Technologies, UniSim Design R443 and onwards from Honeywell and Aspen HYSYS™ v7.3 and onwards from AspenTech.

Core Benefits

No vendor information required

  • Vendors may be willing to provide a design in an early design phase, but will be more and more reluctant as you ask for multiple designs and solutions
  • With CODES you can run as many designs as you want to explore different production scenarios
  • The results are immediate, no need to wait for Vendor feedback

Reliable performance maps

  • Performance maps can be regenerated for different feed compositions, molecular weights and conditions
  • Both thermodynamic and physical characteristics are included, thus the performance maps generated by CODES are more accurate than the traditional process simulator adjusted maps
  • Algorithm for tuning the performance map to match a Vendor provided map makes off-design calculations easy

Relies on decades of compressor design experience

  • Originally developed by Hånde Energy a turbomachinery domain expert company
  • Updated and maintained over 25 years with real life compressor design experience
