Applications

Free Software

Database Administration, Pure Substance, Reaction, Equilibrium, Recalculator 

the Flagship
Process Calculator for MS Excel
also Integration 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 . . .
et al.

in not ideal systems - with the real gas laws
Even if you usually need only a few split time for thermodynamic calculations
AsTher is the correct decision
all you need is, a few basic knowledge in thermodynamics and PC
