Reference number : GC-2017-Q1-00513, amendment number : , agreement type : G, recipient legal name : Englezos, Peter (The University of British Columbia), recipient country : CA, recipient province : nan, recipient city : British Columbia|Colombie-Britannique, recipient postal code : nan, program name english : Engage Grants for Universities, program name french : Subventions d'engagement partenarial pour les universités, program purpose english : This proposal aims to further advance a novel process for the separation of gas mixtures of interest in clean_x000D_
technology area. The process is based on gas hydrate crystallization. Gas mixtures of interest are those_x000D_
containing carbon dioxide and hydrogen. These gases are products of gasification and shift reactions and their_x000D_
separation provides hydrogen (a clean fuel) and also serves to capture carbon dioxide. Another area of_x000D_
application is in flue gas mixtures (products of the combustion of fossil fuels). The key technical idea is the_x000D_
fact that when clathrate hydrates form from a gas mixture such as CO2/H2 or CO2/N2 the clathrate phase is_x000D_
enriched with CO2 and thus, the crystallization serves as a separation stage. This concept has been proven in_x000D_
the laboratory at UBC using small (less than 1 L) crystallizers. In addition the concept has been proven by_x000D_
similar scale equipment in other laboratories around the world. Recently, we have developed a unique bench_x000D_
scale unit at UBC that consists of two 10 L high pressure crstallizers that can operate in an alternating hydrate_x000D_
formation/dissociation mode. The goal of the proposed project is to engage with experts from the process_x000D_
development industry in order to conduct a set of kinetic experiments to obtain information about he time_x000D_
dependence of the formation and decomposition rates in the presence of specific additives which reduce the_x000D_
process pressure and thus the process economics (demanding less compression). The additives to be considered_x000D_
are: tetra-n-butyl ammonium bromide (TBAB); tetra-n-butyl ammonium fluoride (TBAF); and tetra-n-butyl_x000D_
ammonium nitrate (TBANO3). While the use of these additives reduces the pressure requirements the_x000D_
drawback is that they are expected to decrease the kinetics of the process. The proposed work will elucidate the_x000D_
impact of the additives on the dynamics of the process using the new UBC apparatus. The data will provide_x000D_
critical information for the assessment of the feasibility of the separation process for further development., program purpose french : This proposal aims to further advance a novel process for the separation of gas mixtures of interest in clean_x000D_
