Thermodynamic Database
and
Applications

Free Software

Database Administration, Pure Substance, Reaction, Equilibrium, Recalculator 
the Flagship
Process Calculator for MS Excel
Calculate in MS Excel Tables
and integrate the calculations into other process simulation software

useful tools to calculate complex thermodynamic problems for

metallurgical processes, thermal power plant, cement work,
aqueous systems, waste incineration, distillation . . .

in not ideal systems - with the real gas laws
Even if you usually need only a few split time for thermodynamic calculations
- from a simple heat balance to complex process calculations -

AsTher is the correct decision
all you need is, a few basic knowledge in thermodynamics and PC
