yes, you can utilize the vapor-liquid-liquid and vapor-liquid-solid phase envelope utility available in Prode Properties to generate phase diagrams of any mixture,
please note that results will depend from the thermodynamic model which you will select,
for non-hydrocarbons you may consider models as
NRTL with Wong-Sandler mixing rules
UNIQUAC with Wong-Sandler mixing rules
Wilson with Wong-Sandler mixing rules
NRTL with Huron Vidal mixing rules
UNIQUAC with Huron Vidal mixing rules
Wilson with Huron Vidal mixing rules
I have not tested the phase envelope utility with models for electrolytes and I cannot give a comment,
for all other models which I have tested it works fine in Excel 2003, Excel 2007 and Excel 2010 (my version),
also it works in matlab,
you can easily expand the feature (if requested) information is provided in this thread

Carlo,
can I utilize the vapor-liquid-liquid and vapor-liquid-solid phase envelope utility available in Prode Properties
to generate diagrams for non-hydrocarbons as methanol, ammonia et c.
That would be very useful for me.

for water-hydrocarbons equilibria (Vapor-liquid-liquid phase envelope or phase diagram) you may observe several cases:

a) values for water dew point temperature above the values of hydrocarbons dew point,
there is a separate water dew point line, below water dew point line there is liquid water (free water)

b) values for water dew point temperature below the values of hydrocarbons dew point,
there is a three phase line indicating the point where water begin to condense

c) values for water dew point temperature below and above the values of hydrocarbons dew point,
there is a three phase line where water (or hydrocarbons) begin to condensate

you can easily create the different cases with Prode Properties utility for generating the vapor-liquid-liquid phase envelope,
just define a mixture of hydrocarbons, then add different amounts of water
