The Replacement Of Ch4 From Its Hydrate In Quartz Sand With 90:10  70:30  And 50:50 (W-Co2:W-h2o) Carbon Dioxide-In-water (C/w) Emulsions And Liquid Co2 Has Been PerFormed In a Cell With Size Of Empty Set 36 x 200 Mm. The Above Emulsions Were Formed In a New Emulsifier  In Which The Temperature And Pressure Were 285.2 k And 30 Mpa  Respectively  And TH. Emulsions Were Stable For 7-12 H. TH. Results Of Replacing sH.wed tH.t 13.1-27.1%  14.1-25.5%  And 14.6-24.3% Of Ch4 Had Been Displaced From Its Hydrate WIth The Above Emulsions After 24-96 It Of Replacement  Corresponding To About 1.5 Times The Ch4 Replaced With High-pressure Liquid Co2. The Results Also Showed That The Replacement Rate Of Ch4 With The Above Emulsions And Liquid Co2.Decreased From 0.543  0.587  0.608  And 0.348 1/h To 0.083  0.077  0.069  And 0.063 1/H.WItH.TH. Replacement Time Increased From 24 To 96 H. It H.s Been Indicated By tH.s Study tH.t TH. Use Of Co2 Emulsions Is Advantageous Compared To TH. Use Of Liquid Co2 In replacIng cH. From Its H.drate.
