Nearly 50% of CO2 is recovered in the first two hydrate stages and 37% in the third one (Linga et al 2008a) As expected the operating pressure in presence of 1% THF reduced significantly however the rate of hydrate formation and the overall gas consumption for hydrate formation was less compared to the high pressure process without THF

Tetrahydrofuran (THF) is frequently used as a thermodynamic promoter in the development of hydrate based technique which can reduce the hydrate formation pressure especially when methane or hydrogen exists However it is a hard work to describe accurately the phase behavior of THF water system due to their polariti
