Kinetic study on mixed cyclopentane-CO<sub>2</sub> hydrates in the presence of sodium chloride

Hydrate-based technologies are the new topics in the hydrate community with many industrial applications. Recently, gas hydrate-based desalination (HBD) is considered as a novel and potential solution for water treatment. The gas hydrate-based desalination process will be promoted with higher hydrate formation rate and lower operating pressure in the presence of promoters. In this work, Cyclopentane (CP) is used as a hydrate promoter for CO2 hydrate-based desalination process. The main purpose of this research is to obtain the kinetic data of mixed CP−CO2 hydrates in the presence of sodium chloride with 3.5 wt.%. The experimental data for mixed CP−CO2 hydrates in the presence of sodium chloride are obtained in a batch reactor system with a temperature range of 2.3÷10.7 oC and a pressure range of 23÷33 bars. The effects of temperature, pressure, agitation speed and amount of CP on kinetics of mixed CP−CO2 hydrate formation are also reported. This research would provide the new data to progress the hydrate-based desalination and water treatment.
