Refinery

Gas analytical solution with integrated autovalidation for process quality monitoring in refineries

Measuring composition and impurities in refinery gases to optimize process efficiency and hydrogen quality

​

H2S in refinery fuel gas

Refinery fuel gas is a collection of light hydrocarbon gases. To meet environmental regulations the concentration of H2S in fuel gas is monitored before burning instead of SO2 after combustion. Typical range: 0-300 ppm.

​

​

Traditional approach

​

• On-line gas chromatography (GC) has high consumption of carrier gases and requires frequent maintenance and calibration

• Lead-acetate tape analyzers use consumables that require maintenance and special handling to dispose of tape which is classified a hazardous waste

​

​

Our solution

Accurate measurements by SpectraSensors' unique “Differential TDLAS Spectroscopy” helps address changing fuel gas composition with automated 2-point daily validation

​

​

Typical analytes and measuring ranges

​

• Analyte: H2S - Range: 0-10 to 0-300 ppmv

• Analyte: H2O - Range: 0-10 to 0-500 ppmv
