Canadian National Advisory Panel Report 2006
Other than CO2 capture and storage, and gasification, there is no mention of research in the “carbon sector”

Chemical, thermodynamic and transport property knowledge ranked last among NINE surveyed industrial priorities. New processes ranked first.

M. Satyro reminded me of this example from J. M. Douglas’ Conceptual Design of Chemical Processes, McGraw-Hill, N.Y., 1988.

•The oilsands resource and related industrial processes are poorly understood. •Each insight regarding the fundamental behaviours and properties spurs innovation •Greenhouse gas emission intensity has decreased 40 % over the past 20 years!
•Property discovery presents experimental and theoretical challenges and opportunities (innovation).
•Integration of quantitative materials property knowledge and theory from the molecular scale to the nanometer scale to the macro scale is required so that thermophysical properties, transport properties, and phase behaviors identified across these length scales and diverse processing environments are better understood and become exploitable.

Equilibrium Modeling
Speciation is THE challenge for mixtures containing heavy hydrocarbons.

Enthalpy modeling is “solved.” A rare success but implementation of the methods poses challenges.

Pseudo components are determined from chemical analysis + construction algorithms and respect known aspects of molecular properties, elements, functional groups, etc.Tc, Pc, acentric factor are then estimated using classic correlations.
Molecular construction algorithms are under constrained. For any given set of input data, molecular species outcomes* are sensitive to the selection of submolecular building blocks known to be present.**

Conclusions
• Hydrocarbon resource definitions and availability have changed radically over the last century.
• “New” resources are complex and present – materials challenges:
• Thermophysical property measurement & prediction.• Data and observation interpretation.• Translating property knowledge into process knowledge and new processes.
– conceptual challenges: • Theory applicability• Experimental measurement development
• Significant uncertainty remains: • molecular structure• supramolecular structure• phase behavior simulation and prediction• transport properties (mutual diffusion coefficients and rheology)

•The subject and the potential prizes are vast. We are pushed to the frontiers of knowledge in analytical chemistry, computational thermodynamics, fluid physics.
•There are excellent opportunities for individual and collaborative research related to production, transport and refining sectors globally.
•Choose a length scale and a topic and get going!44
