BPT TEX™  is a  process simulator extension that deals with all aspects of Turbo Expander in Design and in Off-Design mode:

  • Expander calculation in Design and Rating (Off-design) mode
  • Compressor calculation in Design and Rating (Off-design) mode
  • Expander Inlet Guide Vane calculations
  • Expander bypass flow
  • Compressor anti-surge recycle flow

Anticipate  all  operating  cases  during  design  and know  the  capability  of your  turbo  expanders  in  operation, maximizing  plant  performance.  This knowledge is essential for gas dew pointing plants, NGL processes, LNG liquefaction and refrigeration systems. BPT TEX™ assists realistic and cost effective plant judgements in a minute.

BPT TEX™ is developed as an unit operation extension model for Petro-SIM 6 and onwards from KBC Advanced Technlogies and Aspen HYSYS V7.3 and onwards from AspenTech and supports both steady state and dynamic calculations.
