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