An Experimental and Numerical Study to Investigate the Temperature Finger Print of Athabasca Bitumen using Accelerating Rate Calorimeter
Abstract
The Accelerating Rate Calorimeter is well suited for investigating the reaction
mechanisms in the Low Temperature Range, Negative Temperature Gradient Region, and High Temperature Range. Athabasca bitumen was used for the experimental study in Closed and Flowing ARC to identify the nature of the oxidation reactions occurring over the different temperature ranges.
The simulation study conducted predicted diffusion to be the transport mechanism for oxygen and other components on either side of the bitumen interface (i.e. within liquid bitumen and the vapor phase). Numerical Model (MOD-1) is a modification of a traditional In Situ Combustion kinetic model whereas Numerical Model (MOD-2) is an improved kinetic model to introduce vaporization coupled with a vapor phase combustion/oxidation reaction. The results indicated that with the addition of mass transfer (diffusion) to the traditional and improved kinetic models, it is possible to predict the temperature regimes.
