The Gas Treating Library is an example library provided with AVEVA Process Simulation. This library provides a collection of pre-defined fluids, reaction submodels, customized stream models, and enhancement factor submodels that you can use in Gas Treating simulations. Each model contains specific help text with a detailed description. To use a Fluid, drag the Fluid and drop it onto a Source model.
The following table lists the models that are available in this Model Library. The table includes very brief descriptions for each model. The Model Help in the AVEVA Process Simulation user interface contains more detailed information for these models. See Open the Model Help for a Model Type or Model Library for more information.
