plot_equilibrium

thermosteam.equilibrium.plot_equilibrium.plot_vle_binary_phase_envelope(chemicals, T=None, P=None, color=None, thermo=None)

Plot the binary phase envelope of two chemicals at a given temperature or pressure.

Parameters

• chemicals (Iterable[Chemical or str]) – Chemicals in equilibrium.

• T (float, optional) – Temperature [K].

• P (float, optional) – Pressure [Pa].

• color (str, optional) – Color of line plot.

• thermo (Thermo, optional) – Thermodynamic property package.

Examples

>>> # from thermosteam import equilibrium as eq
>>> # eq.plot_vle_binary_phase_envelope(['Ethanol', 'Water'], P=101325)

thermosteam.equilibrium.plot_equilibrium.plot_lle_ternary_diagram(carrier, solvent, solute, T, P=101325, thermo=None, color=None, tie_line_points=None, tie_color=None, N_tie_lines=15, N_equilibrium_grids=15)

Plot the ternary phase diagram of chemicals in liquid-liquid equilibrium.

Parameters

• carrier (Chemical) –

• solvent (Chemical) –

• solute (Chemical) –

• T (float, optional) – Temperature [K].

• P (float, optional) – Pressure [Pa]. Defaults to 101325.

• thermo (Thermo, optional) – Thermodynamic property package.

• color (str, optional) – Color of equilibrium line.

• tie_line_points (1d array(size=3), optional) – Additional composition points to create tie lines.

• tie_color (str, optional) – Color of tie lines.

• N_tie_lines (int, optional) – Number of tie lines. The default is 15.

• N_equilibrium_grids (int, optional) – Number of solute composition points to plot. The default is 15.

Examples

>>> # from thermosteam import equilibrium as eq
>>> # eq.plot_lle_ternary_diagram('Water', 'Ethanol', 'EthylAcetate', T=298.15)
