The present invention relates to a dehydration composition and method of use thereof for drying gas streams, in particular natural gas streams, wherein the dehydration composition comprises a (a) glycol and (b) an additive selected so as to increase the viscosity, surface tension, and/or specific gravity of the dehydration composition. Said dehydration composition and method results in the reduction of solvent loss during the dehydration step in a gas dehydration unit.

Amine compositions comprising sterically hindered amines and associated methods are provided. In some embodiments, amine compositions of the present disclosure may be useful for selective removal of H.sub.2S from an acidic gas stream.
