NRTL02 is a two-phase system, while NRTL01 is a single-phase system. What’s the difference between them? What does that mean?

These 02, 01 don’t really mean much; they’re just numbers. In the case of liquid-liquid systems or gas-liquid equilibrium systems, it is necessary to choose between the K(vl) and K(vll) systems. Generally, a prompt will appear when choosing NRTL.

I have a question: Can it be understood that for a single component, it is gas-liquid equilibrium, while for multiple components it is liquid-liquid equilibrium? For the distillation of multiple components, should 02 be chosen?

There is no such difference; Lz, take another look carefully
