摘要
A process stream containing natural gas is conveyed with a glycol containing stream through a pipeline to the downstream location, where they are separated into at least an aqueous phase and a natural gas phase. Glycol is recovered from the aqueous phase to form a stream of recovered glycol. The stream of recovered glycol comprises a least a first portion and a second portion. The first portion of the recovered glycol has passed through a chemical divalent cation removal step whereby divalent cations are removed from a first part of the glycol which passes through said chemical divalent cation removal step. The second portion of said recovered glycol has not passed through the chemical divalent cation removal step.
