Özet

© 2021, Akadémiai Kiadó, Budapest, Hungary.The kinetics of methane gas hydrates formation was obtained by different dual impeller (DI) experiments with full baffle (FB) at 42.5 bar pressure and 2 °C temperature. There were 18 (dual and dual mixed) experiments by the use of pitched blade turbine upward trending (PBTU), pitched blade turbine downward trending (PBTD), rushton turbine (RT) and new impeller design trapezoid turbine in upward trending and down ward trending, TTU and TTD respectively. There were estimations of induction time, duration of hydrate formation, rate of hydrate formation, hydrate formation rate constant, hydrate yield and power consumption. The experiments with radial flow in the upper part of shaft showed better outcomes compared to other combinations for dual impellers in hydrate yield, rate of hydrate formation and hydrate formation rate constant.
