EFFECT OF SDS AND THF ON FORMATION OF METHANE-CONTAINING HYDRATES IN PURE WATER
Gas hydrate formation generally involves gas dissolution, formation of nuclei and growth of new nucleus. On condition of synthesizing experiments without agitation, the formation of hydrate nuclei is comparatively difficult and needs an induction period which is considerably uncertain and random. So...
