Abstract This paper deals with methane hydrate formation from SDS solution of 0.1 wt% in reactor with cooling spiral. Intensity of methane hydrate formation process in a vertical and horizontal cylindrical reactor with a cooled spiral at three fixed volumes of a surfactant solution was compared. The dependence of the gas content of the obtained samples depending on volume of the liquid phase and on the position of the reactor was revealed. The hypotheses about influence of diffusion at the interface and capillary effect on the cooled element on the gas content were examined. Also the efficiency of gas supply mode was tested. The best result for gas consumption in single gas injection mode is 60,21 L•L –1 achieved with a liquid volume of 300 ml in a vertical reactor. The best result for gas consumption in constant gas supply mode is 161,3 L•L –1 achieved with a liquid volume of 500 ml in a horizontal reactor.
