< p>Natural gas hydrate is a solid crystalline compound formed from the combination of water and gas and is part of the clathrite family. Guest gas molecules are trapped within the cavities of the water network, which is formed by hydrogen bonding between water molecules. .They fell. A good example of these gas molecules are compounds smaller than pentane in natural gas such as methane, ethane, propane and carbon dioxide. Gaseous hydrates can be formed by pure gas or a gas mixture consisting of two or more components. They are considered a solid solution in which guest gas molecules and hydrate gases are in contact with the host network (water). Chemical inhibitors are used to prevent gaseous hydrates in gas transmission pipelines. Thermodynamic and kinetic inhibitors are divided into two groups. These inhibitors also differ in the type and extent of use in pipelines.These inhibitors also differ in the type and extent of use in pipelines.
