摘要
Water is the key to hydrate formation. Quite simply put, if there is no water then there is no hydrate. Reducing the water content of a gas stream greatly reduces the likelihood of a hydrate forming. This chapter covers the three common methods for dehydrating natural gas: absorption by a glycol (typically triethylene glycol), refrigeration, and adsorption by molecular sieves. The processes are described in some detail. Simple methods are presented for designing them. Also included are some capital cost estimations.
