Clathrate hydrates or gas hydrates are solid solutions. Water molecules are linked through Clathrate hydrates or gas hydrates are solid solutions. Water molecules are linked through hydrogen bonding and create cavities (host lattice) that can enclose a large variety of molecules hydrogen bonding and create cavities (host lattice) that can enclose a large variety of molecules re is no chemical bonding between the host water m (guests). The olecules and the enclosed guest re is no chemical bonding between the host water mo (guests). The lecules and the enclosed guest molecule. The clathrate hydrate crystal may exist at temperatures below as well as above the molecule. The clathrate hydrate crystal may exist at temperatures below as well as above the normal freezing point of water. Clathrate hydrates have been a source of problems in the energy normal freezing point of water. Clathrate hydrates have been a source of problems in the energy industry because the conditions at which oil and gas are produced, transported, an d processed are industry because the conditions at which oil and gas are produced, transported, and processed are ydrate formation. Accurate prediction of hydrate f frequently suitable for clathrate h ormation and ydrate formation. Accurate prediction of hydrate fo frequently suitable for clathrate h rmation and inhibition condition is required for cost-effective design and operation. Available models have inhibition condition is required for cost-effective design and operation. Available models have limitations in ranges of application and types and compositions of the fluids and inhibitors used. limitations in ranges of application and types and compositions of the fluids and inhibitors used. (such as HYSIM, PROCESS, EQUIPHASE, and The commercial simulation packages available (such as HYSIM, PROCESS, EQUIPHASE, and The commercial simulation packages available are based on empirical relationships for predictin PIPEPHASE) g the effect of inhibitors on PIPEPHASE) are based on empirical relationships for predictin g the effect of inhibitors on rate formation and his paper presents a review about prediction of hyd hydrate formation.
