This paper reports experimental measurements of the isothermal and isochoric formation kinetics of methane hydrate in sodium dodecyl sulphate (SDS) solutions of various concentrations with gas-inducing agitation, and the results are compared with those obtained with normal agitation and no agitation. The experiments were conducted at 274 K with initial gas pressure of 10 MPa. At a given SDS concentration, the gas-inducing agitation gave higher hydrate formation rate than normal agitation and no agitation. Gas inducing agitation of deionized water gave a relatively low methane hydrate formation rate, which could be greatly enhanced by adding SDS. The enhanced kinetics can be attributed to increased gas-liquid contact area, with the coalescence of induced gas bubbles being effectively inhibited by SDS at low concentrations.
