Sulfa-Check® process uses sodium nitrite (NaNO2) in aqueous solution to oxidize H2S to sulfur. This process was developed and patented by NL Treating Chemicals and is now a product of Exxon Energy Chemicals. It will generate NOX in presence of CO2 and O2. Therefore, local air quality emission standard should be consulted. This process is [...]]]></description>

The Institute Francais du Petrole has developed a process for reacting H2S with SO2 to produce water and sulfur. The overall reaction is 2H2S + 862 -» 2H2O + 3S. Figure 7-10 is a simplified diagram of the process. This process involves mixing the H2S and SO2 gases and then contacting them with a liquid [...]]]></description>

An example of a process using O2 to oxidize H2S is the Stretford® process, which is licensed by the British Gas Corporation. In this process the gas stream is washed with an aqueous solution of sodium carbonate, sodium vanadate, and anthraquinone disulfonic acid. Figure 7-9 shows a simplified process diagram of the process.

		<description><![CDATA[The LOCAT® process is a liquid phase oxidation process based on a dilute solution of a proprietary, organically chelated iron in water that converts the hydrogen sulfide to water and elemental sulfur. The process is not reactive to CO2. A small portion of the chelating agent degrades in some side reactions and is lost with [...]]]></description>

		<description><![CDATA[This process is used to treat gas streams containing high concentrations  of H2S. The chemistry of the units involves partial oxidation of  hydrogen sulfide to sulfur dioxide and the catalyticaily promoted reaction  of H2S and SO2 to produce elemental sulfur. The reactions are staged  and are as follows:

		<description><![CDATA[The chemical and solvent processes previously discussed remove acid gases from the gas stream but result in a release of H2S and CO2 when the solvent is regenerated. The release of H2S to the atmosphere may be limited by environmental regulations. The acid gases could be routed to an incinerator or flare, which would convert [...]]]></description>
