摘要： 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).

摘要： A method for separating natural gas liquids (NGLs) from a hydrocarbon gas mixture containing natural gas liquids and methane, comprising the steps of: i) providing a bed of adsorbent selective for NGLs over methane; ii) passing a hydrocarbon gas mixture containing methane and NGL through the bed of adsorbent to at least partially remove NGLs from the gas mixture to produce: (a) NGL-loaded adsorbent and (b) NGL-depleted hydrocarbon gas mixture; iii) recovering the NGL-depleted hydrocarbon gas mixture; iv) regenerating the NGL-loaded adsorbent by at least partially removing NGLs from the adsorbent; and v) sequentially repeating steps (ii) and (iii) using regenerated adsorbent from step (iv).
