Hydrogen Sulfide management in Crude Oil . Managing hydrogen sulfide (H. 2. S) is a challenge at every stage of hydrocarbon production, refining and transportation. Hydrogen sulfide is highly toxic, reduces product value, compromises environmental and safety compliance, corrodes infrastructure, produces noxious odours and has other detrimental A multidimensional gas chromatography method for the analysis of dissolved hydrogen sulfide in liquid crude oil samples is presented. A Deans switch is used to heart-cut light sulfur gases for separation on a secondary column and detection on a sulfur chemiluminescence detector. 1.1 This test method covers the field determination of hydrogen sulfide (H 2 S) in the vapor phase (equilibrium headspace) of a residual fuel oil sample. 1.2 The test method is applicable to liquids with a viscosity range of 5.5 mm 2 /s at 40°C to 50 mm 2 /s at 100°C.
