Recovery
The patented AET Process® LPG
Recovery Unit technology utilizes non-cryogenic absorption to recover C2+
or C3+ natural gas liquids (LPGs) from natural gas streams. The
absorbed LPGs in the rich solvent from the bottom of the LPG absorber
column are fractionated in the solvent regenerator column which separates
LPGs 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 LPG plant can be switched
on-line from ethane plus recovery to propane plus recovery without
affecting the propane recovery levels. The AET LPG plant uses
lighter lean oils. For most applications there are no solvent
make-up requirements. AET can design retrofits for heavy lean oil
facilities.
