ABSTRACT
Part IV of the book is devoted to field treatment and processing operations of natural gas and other associated products. These include dehydration, acidic gas removal (H2S and CO2), and the separation and fractionation of liquid hydrocarbons [known as natural gas liquid (NGL)]. Sweetening of natural gas almost always precedes dehydration and other gas plant processes carried out for the separation of NGL. Dehydration, on the other hand, is usually required before the gas can be sold for pipeline marketing and it is a necessary step in the recovery of NGL from natural gas.
