| Abstract | The replacement of CH(4) 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 CO(2) 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 the emulsions were stable for 7-12 h. The results of replacing showed that 13.1-27.1%, 14.1-25.5%, and 14.6-24.3% of CH(4) had been displaced from its hydrate with the above emulsions after 24-96 It of replacement, corresponding to about 1.5 times the CH(4) replaced with high-pressure liquid CO(2). The results also showed that the replacement rate of CH(4) with the above emulsions and liquid CO(2) 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 the replacement time increased from 24 to 96 h. It has been indicated by this study that the use of CO(2) emulsions is advantageous compared to the use of liquid CO(2) in replacing CH(4) from its hydrate. |

| Keyword | 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. |
