MASSACHUSETTS / ALBERTA / ONTARIO – Tom Thompson, Chairman and CEO of Enviro Innovate Corporation is pleased to announce that Dr. Kim McAuley presented today at the Canadian Chemical Engineering Conference, organized by the Chemical Institute of Canada at the Shaw Conference Centre in Edmonton, Alberta, Canada.  Dr. McAuley presented the results of a CO2 capture modeling project, under the category of “Carbon Reduction and Utilization”.

The presentation introduced the mathematical modelling of four CO2 capture mechanisms behind Enviro Innovate’s process of removing CO2 from flue gas using micron-size water droplets, without the use of a solvent.  In particular: the formation of H2CO3 and its ions; CO2 adsorption/absorption at the water vapour interface; and H2CO3 accumulation at the water vapour interface.

A sensitivity analysis was performed on the model to study the influence of the following parameters on CO2 removal: the CO2 interfacial partition coefficient; the H2CO3 interfacial partition coefficient; the droplet size and velocities; temperature; and, the flue gas condition.

The sensitivity analysis supported experience that the capture rate: increases as droplet sizes decrease; increases as temperature decreases.  The model, sensitive to the interfacial coefficients, supports: substantially more CO2 capture by the water droplets than posited by Henry’s Law; and the high experienced capture rates (80+ percent) of Enviro Innovate’s process.

Continued experimental and modelling work is planned to expand the current model.

About Dr. Kim McAuley

Dr. McAuley is a Professor of Chemical Engineering at Queen’s University where she serves as Associate Dean of Graduate Studies.  Dr. McAuley earned her B.A.Sc. from the University of Waterloo and her Ph.D. from McMaster University.  With her graduate students and postdoctoral fellows, Dr. McAuley develops mathematical models for a wide range of chemical production biochemical processes.  These models are used to predict product quality, production rates and the effectiveness of operating and control systems. Dr. McAuley’s group has developed novel statistical methods for determining appropriate values for kinetic, thermodynamic and mass-transfer parameters that appear in model equations.  These methods are used for selecting and tuning model parameters so that model predictions match the behavior of industrial processes.  Dr. McAuley has developed models for leading international companies including Abbott Point of Care, BASF, DSM, DuPont, Exxon, INEOS, NOVA Chemicals, Praxair and Shell.  She was Associate Editor for Chemical Engineering Journal and serves on the International Advisory Boards for Macromolecular Theory & Simulations and Macromolecular Reaction Engineering and the Board of Directors for the Fields Institute for Research in Mathematical Sciences.  Dr. McAuley has received a Queen Elizabeth II Diamond Jubilee Medal for her modeling research.
