文摘
- •
We combined the modified Tompa model with the van der Waals equation.
- •
The critical lines for a binary gas–liquid mixture were studied.
- •
We focused on the critical lines at the van Laar point and its vicinity.
- •
We found that our P∗, T∗ plots correspond to the type II, type III, type IV behaviors.
