ORIGINAL PAPER Resolving CO2 and methane hydrate formation kinetics
Abstract We analyse the kinetics of CO2 and methane hydrate formation. The characteristic formation times are associated with different steps of the formation process. Conditions for minimising these rate times are identified while maintaining a regime where CO2 hydrate is formed and methane remains...
