BPT PSX™
Reduce model development time by 60%. PSX™ is a relief valve rating model for use within Steady State and Dynamic simulation models. Capacity calculations for all types of relief valves defined in API 520 9th ed.
What is PSX
PSX™ is a highly flexible rating model for relief valves for use with process simulators Petro-SIM® from KBC Advanced Technologies and Aspen HYSYS® from AspenTech. Both steady state and dynamic calculation modes are supported. The benefits are:
- PSX™ provides engineers with an accurate representation of relief valve capacity inside the overall system
- PSX™ provides improved safety study results by increasing relief valve modelling accuracy
PSX™ is more accurate than the default relief valve model because:
- The default model is not accurate for multiphase flow
- The default relief valve model input parameters are static within a simulation
- PSX™ uses the HEM method for base flow calculation
- PSX™ defaults to API 520 for all correction coefficients
- PSX™ eliminates the need to estimate de-rating coefficients as they are continuously updated in a Dynamic simulation
This software comes as an extension for Petro-SIM® 6 and onwards from KBC Advanced Technologies and Aspen HYSYS® v7.3 and onwards from AspenTech.
Core Benefits
