Liquids Recovery - NGL Recovery Unit

The patented AET Process NGL Recovery Unit technology utilizes non-cryogenic absorption to recover C2+ or C3+ natural gas liquids (NGLs) from natural gas streams.  The absorbed NGLs in the rich solvent from the bottom of the NGL absorber column are fractionated in the solvent regenerator column which separates NGLs overhead and lean solvent produced at the bottom.  After heat recuperation, the lean solvent is presaturated with absorber overhead gases.  The chilled solvent flows in the top of the absorber column.  The separated gas from the presaturator separator form the pipeline sales gas.

Depending upon the economics of ethane recovery, the operation of the AET NGL plant can be switched on-line from ethane plus recovery to propane plus recovery without affecting the propane recovery levels.  The AET NGL plant uses lighter lean oils.  For most applications there are no solvent make-up requirements.  AET can design retrofits for heavy lean oil facilities.  Click here for larger view of drawing.
