Mechanisms of methane hydrate crystallization in a semibatch reactor - Influence of a kinetic inhibitor: Polyvinylpyrrolidone
International audience In a previous paper,(1) we proposed a complete model for methane hydrate crystallization from pure water and methane gas in a semibatch reactor. This model takes into account the crucial importance of the rate-determining mass transfer at the gas/liquid interface, coupled with...
