in this study a simple and general chemical association theory is introduced. the concept of infinite equilibrium model is re-examined and true mole fractions of associated species are calculated. the theory is applied to derive the distribution function of associated species. as a severe test the application of presented theory to the van der waals mixture model is introduced in order to perfo...

For some of the EOS models the dimension of equilibrium problem can be reduced. Stability and difficulties in implementation are among the problems of flash calculation. In this work, a new reduction technique is presented to prepare a reduced number of equilibrium equations. Afterwards, a number of appropriate solution variables are selected for the prepared equation system to solve the equati...

2014 The heterogeneous equilibrium in the InGaAsP/HCl/H2 system has been studied at pressure and temperature conditions pertaining to the hydride-VPE growth. The results have been compared with the available experimental data on the growth of the above quaternary alloys lattice-matched to InP. A remarkably good agreement has been achieved with some existing data. Possible causes of discrepancie...
