Predicting process behavior by thermodynamic modeling and simulation.
Power plant owners are continuously seeking ways to improve their assets to make them more efficient, increase capacity and/or reduce environmental impact. All those investment decisions will be based on the expected technical and economic impact they have on the power plant. CerTa Veritas supports decision makers by conducting a feasibility, design or improvement study to qualify and quantify the impact on the asset and thus minimize risk. In the situation that new processes have to be developed or existing processes have to be modified, thermodynamic simulation will determine the effects on performance and operability of the power plant. Therefore, a thermodynamic simulation is the basis for feasibility, design or improvement study. Investment in process simulation has a good pay-back prospect because it minimizes uncertainties for modification and investment decisions. Process models can also be used in power plant operations to predict the expected performance of the plant starting from the prevailing (or expected) site conditions and setpoints, and performance monitoring by comparing actual performance with predicted performance (for the actual site conditions).
Thermodynamic simulation can also be offered as a stand-alone service to power plant owners. This offers the possibility for the power plant owner to add value to an in-house project. Often the (qualitative) knowledge of the plant is available, but the necessary tools to perform (quantitative) process simulations are not available. This gap can be filled with the capabilities and tools of CerTa Veritas.
CerTa Veritas supports plant owners with thermodynamic calculations, both static- and dynamic. For static process simulation CerTa Veritas has developed a simulation tool called Spence® which is dedicated to the utility industry and enables to perform very detailed thermodynamic calculations for all type of conventional and renewable power plants (e.g. fossil fuel fired power plants, waste incinerators and solar (CSP) power plants). For dynamic thermodynamic simulations a commercial package is used that can be adapted in house to specific needs. Dynamic simulation can amongst others be used to analyze and improve the control behaviour of the plant.
