Clathrate hydrates are formed during physical reaction of water and hydrate former gases at high pressure and low temperature. The operating conditions depend on the hydrate former gas. Hydrocarbon and non hydrocarbon gases can form hydrate in the presence of water or ice. Hydrates are found to have many usages such as storage and transportation of gases and desalination of water. A series of experiments have been carried out to desalinate the sour water using a 2.5 lit high pressure reactor at various operating conditions of 0-6 °C and 35-60 bars with carbon dioxide as hydrate former. The consumed carbon dioxide in hydrate formation reaction is calculated based on the pressure loss of CO2 storage tank at operating temperature. The consumed moles of CO2 are directly proportional to the moles of hydrate formed. The amount of water which is used in the formation of hydrate crystals is simply calculated by multiplying the moles of CO2 by six becauseeach molecule of carbon dioxide needs six molecules of water to form hydrate. By investigating the results of the experiment it is found that 5 lit/day of desalinated water can be produced by this reactor.
