Natural Gas Processing | FSC 432: Petroleum Refining

Acid gases (H 2 S and CO 2) are separated usually by absorption in an amine solution, as discussed for H 2 S recovery in a petroleum refinery in Lesson 10. The recovered H 2 S is sent to a combined Claus-SCOT (Tail Gas Treating) unit to be converted to elemental sulfur, as was also discussed in Lesson 10. After removing the acid gases, the natural gas stream is sent to a dehydration unit to ...
