How does the Property Method calculate a specific property?
The properties used in the simulation are classified into categories depending on how they are evaluated:
1. MODELS: models calculate properties by direct use of an empirical expression or a theoretical model. For example:
GAMMA: liquid mixture activity coefficients.Possible MODELS: GMRENON: NRTL original
GMUFAC: UNIFAC
GMUFDMD: UNIFAC, modif. Dormund
.... (up to 32 MODELS)

2. METHODS: in this case the property is evaluated using a thermodynamic expression where required properties are evaluated with MODELS. Different thermodynamic expressions (METHODS) may be available to evaluate a specific property.
For example, four METHODS are available to evaluate the enthalpy of a liquid mixture (HLMX) :
METHOD 1: Empiric expressionHLMX = f(T, P, x_i,
parámetros)
METHOD 2: From the ideal liquid mixture enthalpy (Hi*L) y the excess
enthalpy (HEX).HLMX = Σxi Hi
*L + HEX
METHOD 3: From ideal gas mixture enthalpy (Hmig) and departure
enthalpy (Hdepart):HLMX = Hm
ig + Hdepart
METHOD 4: ElectrolytesHLMX = f(xTRUE)

Types of properties depending on their use and how they are calculated:
MAJOR: Are those properties required for calculations by unit operation models. They ere evaluated according to ROUTES, and may depend on other MAJOR, SUBORDINATE and INTERMEDIATE properties .
Properties: PHI, H, G, S, V, MU, K, D, SIGMA (Pure and mixtures)
SUBORDINATE: these properties are also calculated using ROUTES, but are not directly required for unit operation model calculations. They are used to calculate MAJOR properties.
Ex.: HLXS (excess enthalpy), ...
INTERMEDIATE: calculated by MODELS, they are used to calculate MAJOR and SUBORDINATE properties.
Ex.: GAMMA (activity coefficients),...

Selection criteria:
• Choose the model giving the lowest Residual Root Mean Square.
Non-trustable regressions:
• A standard deviation for a regressed parameter is 0.0, indicating the parameter is at a bound.
• A large residual root mean square error value. Normally, this value should be less than 10 for VLE data and less than 100 for LLE data.
• Your VLE data fail the thermodynamic consistency test.

• /Blocks /D-110 /Design Specs: New = 1• Specify 99.2%mol MeOH in stream 2
Let's see now, forgetting the optimization, how purity may be specified in distillate and bottoms, allowing the software evaluate operating variables.
