Natural Gas Refining The Process

Based on information from USEPA, in AP 42, Fifth Edition, Vol. I, U.S. Environmental Protection Agency, Washington, DC, 2012 (www.epa.gov/ttnchiel/ap42/ch05/index.html). 

Some field processing can be accomplished at or near the well head however, the complete processing of natural gas takes place at a processing plant, usually located in a natural gas producing region (USDOT, 2011). 

As noted earlier, the amine process is the most widely used method for H2S removal. The process is summarized below  

The recovered hydrogen sulfide gas stream may be (1) vented, (2) flared in waste gas flares or modern smokeless flares, (3) incinerated, or (4) utilized for the production of elemental sulfur or sulfuric acid. If the recovered H2S gas stream is not to be utilized as a feedstock for commercial applications, the
