Treatment of Sour Natural Gas

A system and method for treating natural gas, including producing natural gas from a subterranean formation via a wellhead system to a nonthermal plasma (NTP) catalytic unit, converting by the NTP unit carbon dioxide (CO2) and hydrogen sulfide (H2S) in the natural gas into carbon monoxide (CO), elem...

Beschreibung
Zusammenfassung:	A system and method for treating natural gas, including producing natural gas from a subterranean formation via a wellhead system to a nonthermal plasma (NTP) catalytic unit, converting by the NTP unit carbon dioxide (CO2) and hydrogen sulfide (H2S) in the natural gas into carbon monoxide (CO), elemental sulfur (S), and hydrogen (H2), and removing the elemental sulfur as liquid elemental sulfur to give treated natural gas. The NTP unit may convert methane (CH4) in the natural gas to heavier hydrocarbons.
