  • Processing NH3 acid gas in a sulphur recovery unit

    In the industry’s experience with NH3-burning SRUs, the SWS acid gas is processed in the SRU along with the amine acid gas for recovery of elemental sulphur from hydrogen sulphide (H2S), and the NH3 content of the aggregate acid gas has been low enough that the increase in SRU equipment sizes to process the NH3 and the loss in Claus sulphur recovery can be tolerated. For these low NH3 content acid gas feeds, the furnace temperature is, or can be designed, high enough to ensure complete NH3
