  1. 3. A process unit designed to take tail gas from a Claus sulfur recovery plant and remove additional sulfur with the goal of meeting environmental sulfur emission standards
  2. 4. The process in which 1/3 of the H₂S in the acid gas feed is burned to SO₂, which is then reacted with the remaining H₂S to produce sulfur. This is also referred to as the modified Claus process.
  3. 6. Natural gas after removal of H₂O.
  4. 7. Natural gas which doesn’t contain H₂S and CO₂.
  5. 8. The period in which a process stream will be contained within a certain volume or piece of equipment, measured in seconds
  6. 11. Natural gas which contains H₂O.
  7. 12. Natural gas which contains H₂S and CO₂ gases (acid).
  8. 13. Gas associated with liquids

  1. 1. Gas produced from gas wells without liquids.
  2. 2. When other hydrocarbons are present, the natural gas is 'wet’.
  3. 5. Feed stream to sulfur recovery plant consisting of H₂S, CO₂, H₂O, and usually less than 2 mol % hydrocarbons.
  4. 9. Pentanes and heavier, C₅+.
  5. 10. Natural gas is considered 'dry' when it is almost pure methane, having most of the other commonly associated hydrocarbons removed.
