Good agreement between simulation results and the experimental data suggested that the proposed model was well constructed and simulation exercise was successful. The proposed model was solved with the software of EQUATRAN-G. heterogeneous structures in gas–solid flow, and the macro-scale of product distribution over riser reactor have been established using multi-scale modeling method and integrated by the multi-domain strategy.

Micro-scale of kinetics in catalyst particles, meso-scale of clusters, voids, dense phase, dilute phases, and. Multi-scale model considered the heat transfer, mass transfer, momentum transfer, fluid flow with reactions together at different spatiotemporal scales for the riser reactor of secondary reactions of fluid catalytic cracking gasoline (SRFCCG) process has been preformed in this work. Much of this is subsequently used to develop methods for preparation of Eqo's and the more complex but evidently essential equivalent systems (EqS's) needed to model live crudes. This paper places EACN in perspective by means of the three-parameter representation, explores parallel effects of temperature and alcohol cosolvents, and reveals essential nonlinearities in optimal salinity as a function of oil composition (and hence molar volume) for mixtures of various oils. If, in addition to equivalence, oils are required to have equal viscosities and similar phase behavior as a function of surfactant concentration, then it may be possible to replace microemulsion floods of live crude at high pressure with floods of appropriately diluted dead crude at low pressure.

It then becomes possible to introduce the idea of equivalent oils (Eqo's) as a replacement for the equivalent alkane carbon number (EACN), which is shown to lack some of the properties needed to implement efficient preliminary screening of microemulsions for EOR.īroadly speaking, oils are 'equivalent' when they have the same molar volumes, optimal salinities, and solubilization parameters. When optimal salinity, Cϕ, and solubilization parameter Vo/Vs are augmented by oil molar volume, Vmo, the resulting three-parameter representation provides a more precise description of microemulsion phase behavior than has previously been available.
