description The invention provides a process for the production of a lean liquid hydrate inhibitor composition from a rich liquid hydrate inhibitor composition in which the liquid hydrate inhibitor has a boiling point above that of water, which process comprises: (a) feeding said rich liquid hydrate inhibitor composition to a first distillation vessel; (b) withdrawing a water and inhibitor containing vapor from said first distillation vessel and feeding it to a second distillation vessel; (c) withdrawing water vapor from said second distillation vessel; (d) withdrawing a lean hydrate inhibitor composition from said second distillation vessel in liquid form; (e) withdrawing a lean hydrate inhibitor composition from said first distillation vessel in liquid form; (f) withdrawing liquid from said first distillation vessel and removing solids therefrom; wherein the withdrawal of steps (e) and (f) may be of a single liquid stream and wherein at least a portion of the lean hydrate inhibitor composition withdrawn from said first distillation vessel is not recycled into said first distillation vessel.
