The effect of aqueous solution on the formation of natural gas hydrates has been studied. The natural gas mixture has been used as the gas condensate mixture. The composition of the gas mixture had components: CH4 - 94.3; C2H6 - 3; C3H8 - 1.2; C4H10 - 0.12; air - the rest. The moment of the formation of gas hydrate plugs in experiment installation has been determined as follows. The pressure drop was determined on installation while the natural gas is flowing through the pipeline of the installation with the local resistance. During the formation process of natural gas hydrates in the zone of the local resistance of the installation the pressure drops to zero distinctly when the gas flows out of the installation. At this time gas hydrate plugs prevent natural gas from flowing out of the installation and the movement of gas stops. By this method the moment of the formation and accumulation of natural gas hydrates in the installation can be determined. After treating of natural gas with an aqueous solution of sulphonol, it is passed through the pipeline of the installation. It is determined that treating of natural gas with sulphonol solution leads to a significant increase in the volume of natural gas. So, the speed of the process decreases significantly.
