What physical property methods can be used for a mixture composed of dichloroethane, hydrogen chloride, and vinyl chloride at room temperature and low pressure? The example uses RK-soave, but I think the activity coefficient method such as NRTL is better. This post was last edited by visavis on 2009-3-30 16:20]
Specifically, it also depends on the operating conditions; if all three phases are gaseous and hydrogen chloride exists as molecules, polarity cannot be manifested, in which case a phase diagram can be used. The state agenda is only considered to be used under liquid-phase conditions.
Generally, for vapor-liquid equilibrium, it should be the NRTL or Wilson equation for the liquid phase, and the SRK or PR equation for the gas phase, right? Let’s discuss this
