Marc Bacon


Zakiah A. Kassam

Monday, October 20

08:30–09:30, Confederation I
Marc Bacon, VP Engineering, Plasco Energy Group
Zakiah A Kassam, Manager of Technical Marketing, Plasco Energy Group

Abstract: Leading Sustainable Ventures: An Exercise in Stewardship
Amidst the alarming realities of global warming, dwindling energy supplies, and shortages in water, PlascoEnergy has incorporated environmental stewardship into its technology, business model, and engagement with stakeholders. Mr. Marc Bacon, VP Engineering of Plasco Energy Group, will discuss key environmental challenges, the importance of environmental stewardship, and how the ethic of stewardship has been incorporated into the design of the Plasco Conversion System, PlascoEnergy's business model and commercial contacts, and its partnerships with institutions and communities. The presentation will also discuss the challenges in deploying a new environmental technology such as developing new policy frameworks, constructing new analyses, and educating stakeholders.

 

Brian Foody

 

Tuesday, October 21

08:30–09:30, Confederation I
Brian Foody, CEO, Iogen Corporation

Abstract: Cellulose Ethanol: Driving Commercialization
As with all emerging technologies, there are many essential steps along the road to successful commercialization of cellulosic ethanol. Brian Foody, CEO, Iogen Corporation, will share Iogen's experiences and insights gained through more than 25 years of research and development and operation since 2004, of one of the world's only cellulose ethanol demonstration plants. Mr. Foody will also address environmental benefits of cellulosic ethanol and how biofuels advance government policies aimed at reducing GHGs and CO2 emissions. He will also address cellulosic ethanol in the context of energy for a sustainable society.

Krishnaswamy Nandakumar, FCIC, GASCO Chair Professor, Petroleum Institute


Abstract: Multiphase Computational Fluid Dynamics: A new tool to aid in scale up of chemical processes
Nandakumar will present an overview of his research over the last two decades in using computational fluid dynamics to explore multiphase flows. On the fundamental side, we have developed algorithms for direct numerical simulation of multiphase flows. For dispersed rigid particles as in suspension flows, sedimentation etc, we couple the Navier-Stokes equations with the rigid body dynamics in a rigorous fashion to track the particle motion in a fluid. For deformable bubbles/droplets dispersed in another fluid, we also track their motion in an Eulerian grid. Discontinuous basis functions are used to enrich the function space near the fluid/fluid interface. The two classes of algorithms show great promise in attempting direct simulation of multiphase flows with many particles or droplets, from which we can extract statistically meaningful average behaviour of suspensions or bubbly flows.
On the other hand, there is an immediate need to study flow of complex fluids of industrial importance. Such cases include polymer blending processes involving melting, deformation and break-up, corrosion-erosion in pipelines and process vessels, mass transfer in packed beds or in Sieve trays, slurry flows etc. In such studies we use volume averaged equations as the basis of CFD models coupled with experimental validation of such predictions in an effort to develop scale invariant closure models that are needed as part of the volume averaged CFD models. We will discuss several of these examples.
