Formation Kinetics of Structure H Gas Hydrate
This paper investigates the kinetics of structure H (sH) formation kinetics above and below the structure I (sI) formation equilibrium curve at temperatures of between 2°C and 6°C. Methane was used as a help gas and methylcyclohexane (MCH) was used as sH former. It was concluded that in the points above the sI formation equilibrium curve, at the first, the sI forms, and then converts to sH be...

this paper investigates the kinetics of structure h (sh) formation kinetics above and below the structure i (si) formation equilibrium curve at temperatures of between 2â°c and 6â°c. methane was used as a help gas and methylcyclohexane (mch) was used as sh former. it was concluded that in the points above the si formation equilibrium curve, at the first, the si forms, and then converts to sh be...
متن کاملKinetics of hydrate dissociation at a pressure of 0.1 MPa
Experimental data on the kinetics of propane hydrate dissociation at 0.1 MPa and different external temperatures were obtained. A two-stage mechanism of hydrate dissociation was observed visually. In the first stage hydrate dissociated into metastable water and gas. During the second stage the metastable water crystallized into ice. The release of metastable water during hydrate dissociation an...
متن کاملKinetics of Propane Hydrate Formation in Agitated Reactor: A Mass Transfer Approach
Understanding the kinetics of gas hydrate formation is essential to model and predict the hydrate formation (or dissociation) process. In the present paper, we investigated the formation of pure propane gas hydrate as a former gas. In this regard, several experiments were conducted to measure the rate of hydrate formation under various pressures (410 to 510 kPa) and temperatures (274 K to 277 K...
متن کاملInvestigation the Kinetics of CO2 Hydrate Formation in the Water System + CTAB + TBAF + ZnO
In this study, the kinetics of gas hydrate formation in the presence of tetra-n-butyl ammonium fluoride (TBAF) and cetyl trimethyl ammonium bromide surface active ingredient (CTAB) with zinc nano oxide (ZnO) are investigated and the most important kinetic parameters of hydrate formation such as their induction time and storage capacity were measured. The kinetic experiments were carried out in ...
