The promotion effect of two polymers and three surfactants on methane hydrate formation was investigated in a high-pressure system. For all of the tested chemicals, 1 wt % aqueous solutions were prepared and methane hydrate was formed in those media to detect their effect on hydrate formation rate. It was determined that Igepal-520 is the most effective promoter on methane hydrate formation rate with respect to a reference test carried out by using only pure water.
