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
