Vapor-Liquid Equilibrium
Vapor-liquid equilibrium conditions are calculated for mixtures of up to six components. Compositions of either the liquid or vapor phase can be specified, from which the equilibrium phase conditions can be calculated. Flash calculations for incoming streams can also be solved.
CaCO3 -> CaO + CO2
NaCl + NH3 + CO2 + H2O -> NaHCO3 + NH4Cl
2 NaHCO3 -> Na2CO3 + H2O + CO2
CaO + H2O -> Ca(OH)2
Ca(OH)2 + 2 NH4Cl -> CaCl2 + 2 NH3 + 2 H2O
