Estimation ofEnthalpy of Dissociation and Hydration Number in Single Hydrate Systems

This report is about the study on clathrate hydrates. Clathrate hydrates have been intensively studied due to its potential to be one of the energy sources. This project focuses on clathrate hydrates thermodynamics properties which are the enthalpy of dissociation and hydration number. Experimental work can be done to estimate both values, the enthalpy of dissociation and hydration number. However, due to time constraints as well as the limited laboratory equipments, the value will be determined by using theoretical calculation. By using the Clapeyron equation, both enthalpy of dissociation and hydration for selected systems will be estimated. The Clapeyron equation is chosen because it takes into account the volume changes of the systems and the solubility of water in gases at appropriate temperature and pressure. Available data such as phase equilibrium data are the key important in determining the values. The value estimated will be validated with the previous studied data. The values estimated will be documented and these values can be very useful as a base in order to investigate the potential of clathrate hydrates to be one of the energy sources
