BPT 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.
