Title: Turboexpander plant designs can provide high ethane recovery without inlet CO/sub 2/ removal

Journal Article · · Oil Gas J.; (United States)
OSTI ID:6432429

Several new turboexpander gas-plant schemes offer two advantages over conventional processes: they can recover over 85% of the natural gas stream's ethane while handling higher inlet CO/sub 2/ concentrations without freezing - this saves considerable costs by allowing smaller CO/sub 2/ removal units or eliminating the need for them entirely, and the liquids recovery system requires no more external horsepower and in many cases, even less; this maximized the quantity of liquids recovered per unit of energy input, thus further lowering costs. The economic benefits associated with the proved plant designs make the processes attractive even for inlet gas streams containing little or no CO/sub 2/.
