Effect of Different Surfactants on Gas Hydrate Formation
Capturing carbon dioxide (CO2) by forming hydrate is an attractive technology for reducing the greenhouse effect.The most primary challenges are high energy consumption,low hydrate formation rate,and separation efficiency.In order to solve the problem of slow formation rate of gas hydrate,the effects of sodium dodecyl benzene sulfonate (SDBS),hexadecyl trimethyl ammonium bromide (CTAB) and polyethylene oxide-polypropylene oxide-polyethylene oxide triblock copolymer (P123) on the formation of carbon dioxide hydrate have been investigated.The results show that CTAB,SDBS and P123 can reduce phase equilibrium point of CO2 hydrate.The lower pressure of hydration reaction system,the larger induction time of CO2 hydrate reduction.Maximum promotion effect of SDBS was observed at 700 mg / kg which was comparable with that of CTAB at 300 mg / kg and P123 at 500 mg / kg.The study has a certain significance to improve the rate of hydrate formation.
