Here's what I get.


Acid gas is a significant component of unprocessed natural gas.

The major constituents of acid gas are hydrogen sulfide and carbon dioxide.

They must be removed from natural gas for several reasons:

  1. The natural gas must meet the customers' specifications.
  2. Both gases are acidic and corrosive to machinery and piping.
  3. Hydrogen sulfide is foul-smelling and toxic.
  4. Carbon dioxide is a major greenhouse gas, so its levels in the exhaust gas are controlled by environmental regulations.
  5. The recovered hydrogen sulfide can be converted into sulfur or other saleable products, thereby reducing the cost of refining.
