نویسندگان
چکیده
In this work, the SAFT-VR Mie equation of state is used in conjunction with Dubinin-Radushkevich-Astakhov (DRA) and Steele potentials, according to Multicomponent Potential Theory Adsorption (MPTA), model thermodynamic behavior fluids confined porous media. The problem specifications are temperature, volume, number moles each component, yielding a Helmholtz energy-minimization problem. Calculation results show very good agreement experimental adsorption data for systems methane, nitrogen, carbon dioxide, ethane, ethylene, isobutane adsorbed on activated molecular sieve.

Application of Crossover Theory to the SAFT-VR Equation of State: SAFT-VRX for Pure Fluids
The molecular-based SAFT equation of state has proven to be very versatile in the prediction of fluid phase equilibria. However, in common with all analytic equations of state, SAFT exhibits classical behavior in the critical region rather than the nonanalytical, singular behavior seen in real fluids. As a result, accurate agreement over the whole phase diagram cannot be obtained and must be lo...

abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...

The statistical associating fluid theory for potentials of variable range plus dipole (SAFT-VR+D) is extended to study associating dipolar fluids. In the SAFT-VR+D approach dipolar interactions are taken into account through the use of the generalized mean spherical approximation to describe a reference fluid of dipolar square-well segments. This enables the effect of the dipolar interactions o...
متن کاملA crossover SAFT-VR equation of state for pure fluids: preliminary results for light hydrocarbons
SAFT is perhaps the most versatile, fundamentally, based engineering equation of state in use today. However, in common with all analytic equations of state, SAFT exhibits classical behavior in the critical region rather than the non-analytical, singular behavior seen in real fluids. Recently, so-called crossover equations of state have been developed which solve this shortcoming by incorporati...
