Gas Networks & Compression Station Analyses
The effect of changing operating conditions is predicted using pipeline machinery simulations, and the results are shown on a compressor map.
Pipeline simulations of various scenarios are used to optimize the system with regards to power usage, transport energy, and flow ratio.
A gas network analysis was used to predict the pressure and temperature of the natural gas pipeline as it travels through several compressor stations along a pipeline.
Compressor operating point trajectory at various specific gravity points while operating with a fixed pressure ratio and speed.
Compressor power consumed variation, relative to the changing specific gravity, of a compressor operating with a fixed pressure ratio and speed.
Analysis of a gas pipeline was used to create system curves that assist with compressor selection and operation strategies.
Southwest Research Institute® (SwRI®) performs steady state and transient modeling of gas networks and compressor stations to determine if the system will safely meet the design requirements. These analyses have been utilized for:
- Transient analyses
- Centrifugal compressor surge control system design
- Startup and shutdown
- Transmission pipeline/facility hydraulic evaluation
- Design and optimization of new installations
- Modifications of existing facilities
- Hydraulic operation issues
- Delivery predictions under various operating conditions
- Pressure limits
- Temperature limits
- Surge margin
- System capacity
- Valve manifold transient pressure and flow predictions
- Compressor failures related to fluid/structure vibrations
- Pipeline ruptures
Field troubleshooting and benchmarking services can also be provided.
