Manasrah, Azfar Hassan and Nashaat N. Nassar The thermal reactivity of petroleum coke was enhanced by using the oxy-cracking technique (ie, a combination of oxidation and cracking reactions at mild temperature and pressure). We showed that the oxy-cracked petcoke is easier and faster to oxidize (475°C) compared with virgin petcoke (540°C), without impacting the heating value ∼ 30 MJ/kg. The nitrogen and sulphur contents in the oxy-cracked petcoke are much lower than that of virgin petcoke. These findings suggest that the use of oxy-cracked petcoke as an alternative or initiator fuel for coal power generation would be safer, more efficient, and less polluting than virgin petcoke.1 Pressure-driven displacement flows of yield stress fluids: Viscosity ratio effects-p. 2804 Ali Eslami, Roozbeh Mollaabbasi, Ali Roustaei and Seyed Mohammad Taghavi The pressure-driven displacement flow of two miscible fluids along a 2D plane channel has been computationally studied. A heavy Newtonian fluid displaces a light yield stress fluid. Various displacement flow behaviours are mainly governed by the Bingham number, the Reynolds number, the viscosity ratio, the densimetric Froude number, and the channel inclination. The viscosity ratio significantly affects the displacement flow patterns and regime classifications.2 Assessment of commercial hydrate inhibitors using the 3-in-1 method-p. 2818 Sebastian Ovalle, Camilo Martinez, Luna Bonilla, Andres Lara and Juan G. Beltran Gas hydrate systems containing four types of commercial inhibitors were studied with the 3-in-1 method. A single reactor allowed us to study phase equilibria and apparent kinetics, while acquiring high resolution images of hydrate formation and dissociation processes. Tight control of pressure and temperature produced highly repeatable morphologies. Furthermore, with our reactor/method, multiple subcoolings could be assessed in a single experiment. Overall, we present an innovative technology that with little time investment and small sample sizes obtains reliable characterization of inhibited hydrate systems.3 Multiscale modelling of mass transfer in gas jets and bubble plumes-p. 2843 Devin J. O'Malley and Jan B. Haelssig A new multiscale CFD model was developed for the simulation of mass transfer in gas jets and bubble plumes. The model combines the volume-of-fluid method for interface tracking to resolve jetting effects in the near field and the drift-flux model to simulate flow of the dispersed bubble plume in the far field. The transition between the governing flow and mass transfer models is controlled by the local phase fraction. The model was validated using experimental data for fluid dynamics in a vertical bubble plume and mass transfer in a horizontally-injected gas jet that transitions to a bubble plume.4 REFERENCES 1A.
