Experimental study of the dissociation of natural methane hydrate in the channel in the presence of air flow

Abstract

Experimental studies have been carried out on the combustion of natural gas hydrate at different rates of oxidant U (air) in the laminar flow regime and at a fixed channel height. It is established that the dissociation rate J is related to the velocity U in a non-linear manner. With an increase in rate from 0 to 0.6 m/s, the dissociation rate increases and reaches a maximum. With a further increase in rate, J decreases. The dissociation rate does not depend on the initial concentration of methane in the sample. Experimental dependences of the effect of U on the dissociation rate of a natural hydrate in a channel have been obtained for the first time. The conducted studies are important for further development of natural hydrate combustion technologies.
