Measurements of Hydrate Dissociation Temperature of Methane, Ethane, and CO2 in the Absence of Any Aqueous Phase and Prediction with the Cubic Plus Association Equation of State

摘要: Gas hydrate formation is undesired in processing and gas distribution. Therefore, it important to have a thermodynamic model that predicts correctly formation. Hydrate very well studied the literature presence of liquid water, models predict its However, only little information can be found concerning without an aqueous phase. A new experimental procedure combining equilibrium cell with water measurement by Karl Fischer coulometer was developed. The content vapor phase measured as function temperature, dissociation temperature determined slope change curve. In first step, temperatures methane hydrate, ethane carbon dioxide were at different pressures for amounts. second obtained results compared data ca...
