Use this window to define the phases for components in the simulation. The phase specification determines how the components will be handled in equilibrium calculations. Phase assignment is meaningful only for simulations containing solids.
Usage
From the Component Selection Main Window, push the Component Phases button.
Default Phase for User-defined Components
Unless the phase of a User-Defined component is explicitly defined in the table below, it will use this entry. By default, the component may exist in the vapor and liquid phases but not in the solid. For other options, select the required phases from the drop-down list.
Component Phases
All components in the simulation (except assay components) appear in the list. The Type entry will show if it is a Library, User-defined, Petroleum or Polymer component. The phase selections for User-defined or petroleum components default to the entry defined in the Default Phase for User-defined Components. The default for library components will be taken from the databank. Polymers default to Vapor-Liquid-Solid.
Available Phase selections are:
Vapor-liquid: A component or range of components listed in this entry exhibit vapor-liquid phase equilibria. They may exist in the vapor or liquid phases or both.
Liquid-solid: Defines a component or range of components that exhibit liquid-solid phase equilibria. Components can exist in the liquid or solid phase or both. Examples of this class of components are polymers and salts.
Vapor-liquid-solid: Defines a component or range of components that exhibit vapor-liquid-solid phase equilibria. Components can exist in any combination of phases. Examples of this class of components are polymers, CO2 and naphthalene.
Solid: Defines a component or range of components that exist only in the solid phase. Examples of this class of components are zeolyte catalyst and coal.
