|Sour Gas (SRU)||H2S||0-100% H2S||OMA-300 Process Analyzer|
H2S is an extremely dangerous chemical which occurs naturally in fossil fuels and is removed through refining processes. Gas that contains significant amounts of H2S is considered “sour gas” due to the foul aroma from H2S and other sulfur containing compounds.
The primary process for removing H2S from sour natural gas, sour water stripper gas and hydrotreater gas is the amine treatment process in a Sulfur Recovery Unit (SRU). The sour gas is run through an absorption tower containing an aqueous amine solution. The amine selectively absorbs the H2S from the gas stream, which results in a treated “sweet gas”. To achieve efficient control of the amine unit cycle time, the operator must know the concentration of the H2S in the sour gas.
The OMA-300 Process Analyzer can be implemented in this process to provide H2S measurements in the incoming sour gas stream. The OMA-300 Process Analyzer continuously outputs H2S readings, providing new measurements every 5 seconds. Response time is critical in the amine treatment unit in order to keep it running as efficiently as possible.
In the diagram below, the sour gas analysis point is identified by AT1.
The specifications below represent performance of the OMA-300 Process Analyzer in a typical sour gas application.
