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.
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.
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.
