Facilitates realistic representation of orifice and venturi

Introduction:
Orifice and venturi flow meters are not commonly available as standard unit operations in process simulators. If a model is required, the user currently has to estimate or approximate the operation of this equipment. BPT-ROX provides a much more accurate representation.
 
When evaluating orifice capacity, one has to take into account changes in the process conditions. Changes in backpressure and changes in fluid going into the orifice greatly effects the capacity.
 
Correct orifice capacity is vital to ensure accurate modelling and to ensure safe design of any facilty.
 
What is BPT-ROX?
 

BPT-ROX is a process simulator unit operation for orifice and venturi flow meters and restriction orifice modelling. BPT-ROX can be used in both steady state and dynamic simulations.

Since orifice and venturi flow meters are not commonly available as standard unit operations in process simulators, if a model or either unit is required, the user currently has to estimate or approximate the operation of this equipment.

This software comes as an extension for UniSim Design, Petro-SIM and HYSYS.

No user estimate calculations needed

BPT-ROX uses the Homogenous Equilibrium Method (HEM) as the general flow calculation method for restriction orifices and uses ISO5167 as the basis for calculation of orifice flow meters and venturi flow meters.
 
Flexibility
 
BPT-ROX is not intended to be an orifice plate design tool, but if the user wishes to do a design, he or she can quickly adjust the main dimensions to find an orifice/throat size that fits the needs of the process.
Benefits and key findings:
  • Improve model accuracy
  • Improve model readability
  • Works both in steady state and dynamic mode
  • Move away from spreadsheets that need to be verified over and over again
  • Improve compressor anti surge studies
  • BPT-ROX assists engineers defining, testing and specifying the flow requirements
