摘要: An attempt has been made to form continuously either a structure-I or structure-H hydrate using methane as the common guest substance and methylcyclohexane second for hydrate. The experimental technique we tested was spray water into high-pressure chamber charged with gas. In experiments hydrate, droplets sprayed from single nozzle at top of coalesced pool underlying gas phase. fell onto layer superposed on then merged pool. Water drained bottom circulated back through nozzle. During this circulation, passed heat exchanger outside release generated by formation. pressure in maintained prescribed level (typically 2.5−3.7 MPa) supplying metha...
