摘要： Disclosed is a method of sequentially separating and recovering one or more NGLs (129, 229) from a natural gas feedstream (3). Specifically, a raw natural gas feedstream (3) is passed through two or more NGLs separation unit (100, 200) wherein each separation unit removes one or more NGLs from the natural gas feedstream to provide a methane-rich natural gas supply (205). Each separation unit employs an adsorption media and has an adsorption step and a media regeneration step wherein the regeneration step may be operated as a batch process, a semi-continuous process, or a continuous process. One embodiment of this method provides for the use of a different regenerable adsorbent media in each separation unit.

摘要： Disclosed is an improved process for regenerating solvent used to remove contaminants from a fluid stream. Said process comprises a solvent regeneration system (10) comprising a rich/lean solvent stripper column (29), reboiler (50), condenser (36), and reflux receiver (38) wherein the improvement is the location 46 of the condensed stripper gas return from the reflux receiver.

摘要： An improved composition and method for acid gas treatment, comprising an effective amount of tetraethylene glycol dimethyl ether in combination with other alkyl ethers of alkylene glycols. Utilization of a mixture consisting of 60 to 84 weight percent tetraethylene glycol dimethyl ether produces significant benefits in freeze point reduction. A solvent based said mixture of 60 to 84 weight percent tetraethylene glycol dimethyl ether can be used neat or as an aqueous mixture or can be added to the existing recirculating solvent stream to change the concentration of tetraethylene glycol dimethyl ether to a satisfactory level.
