Blends of bitumen, clay, and quartz in water are obtained from the surface mining Athabasca Oil Sands. To facilitate its transportation through pipelines, this mixture is usually diluted with locally produced naphtha. As a result this, naphtha has to be recovered later, recovery unit (NRU). The NRU process complex one requires knowledge Vapour-Liquid-Liquid Equilibrium (VLLE) thermodynamics. pr...

We propose a new form for equations of state (EOS) of thermodynamic systems in the Ising universality class. The new EOS guarantees the correct universality and scaling behavior close to critical points and is formulated in terms of the scaling fields only – unlike the traditional Schofield representation, which uses a parametric form. Close to a critical point, the new EOS expresses the square...

An examination of the program of the next meeting of distillation and absorption indicates there are only a few lectures on thermodynamcis. The authors asked some important companies to give their view of the trends in thermodynamics. This plenary lecture concerns some of the remaining challenges in the thermodynamics related to distillation: data banks and locations for measuring experimental ...
