Hydrogen Sulfide - an overview ScienceDirect Topics

Hydrogen sulfide is a little heavier than air; its relative density is 1.19.Hydrogen sulfide gets together in the low-lying region easily.If the hydrogen sulfide monitor (detector) is too far from the monitoring level,it can't monitor the hydrogen sulfide concentration correctly (Figs.10-3-1,10-3-2).High Temperature Hydrogen Sulfide Corrosion CORROSIONOf the conventional alloy steels tested,only the 18-8 chrome nickel and higher alloys have shown good resistance to this type of corrosion over a wide range of pressure,temperature and hydrogen sulfide concentration.It was found that aluminum coated steels also showed very good corrosion resistance.HYDROGEN SULFIDE MEASUREMENT AND DETECTIONJan 24,2003 PDF The Effect of H2S Concentration and Temperature on#0183;As the name implies,hydrogen sulfide analyzers using the lead acetate detector are based on the reaction of hydrogen sulfide with lead acetate.The initially white lead acetate turns brown when exposed to hydrogen sulfide in the presence of water.The greater the amount of H 2 S in the sample,the darker the stain that forms on the tape.
