The package implements functions to work with substances and mixtures described by the modified Benedict-Webb-Rubin (MBWR) equation of state.
To construct an set of parameters for a component, use
MBWREoSComponent(;name="No Name", critical_pressure, critical_temperature, acentric_factor, Zc, molar_mass, carbon_number::Integer)The temperatures must be in absolute scale (e.g., in Kelvins).
The parameters can be loaded from a file (using CubicEoSDatabase.jl):
methane = load(MBWREoSComponent, name = "methane")Mixtures are constructed via
MBWREoSMixture(; components::AbstractVector{<:MBWREoSComponent})To get the pressure of a pure component:
pressure(component; nmol, volume, temperature)To get the estimate of the saturation pressure at a given temperature:
wilson_saturation_pressure(component, RT)
