Abstract

A continuous method for treating a well stream from natural gas or petroleum production comprising the steps of: i) recovering the well stream from a natural gas or petroleum formation wherein the well stream comprises mono and divalent salts including scale-forming cations, ii) adding glycol to the well stream to form a glycol mixture, iii) heating the glycol mixture to a temperature of at least 35C, iv) passing the glycol mixture through a packed bed of strong acid ion exchange resin to remove at least a portion of the scale forming cations and to form a softened effluent, v) removing at least a portion of water present in the effluent to precipitate monovalent salts, and vi) repeating steps i) through v) and reusing at least a portion of the glycol from step v) in step ii).
