Details

Applications

Hydrogen sulfide (H₂S) detector with pump-suction style is used to monitor the concentrtion of H₂S in the dangerous areas like oil recovery, petrochemical, metallurgy, sewage treatment, exhaust emission, chemical, agriculture, refinery and so on.

Tips: Gas characteristics and detection of hydrogen sulfide

Hydrogen sulfide (H2S) is a flammable colorless gas with a typical smell of rotten eggs. It is easily soluble in water; at the temperature of 20℃, 2.9 volume of is soluble in 1 volume of water. Hydrogen sulfide is also soluble in alcohols, aldehydes, carbon disulfide, petroleum solvents and crude oil.

Hydrogen sulfide is five to six times more toxic than carbon monoxide and is almost as toxic as cyanide. At the low concentrations (0.13 - 4.6 ppm), hydrogen sulfide smells rotten eggs. When the H2S concentration is higher than 4.6 ppm, the human sense of smell is quickly passivited and the odour of rotten eggs is not smelled. This situation is the most dangerous.

When the H2S concentration is between 4.3 and 46%, the mixed gas formed with the air will explode in a fire. The burned product, SO2, is still toxic and will continue to harm the eyes and lungs of the human body. The work of preventing poisoning during burning cannot be relaxed.

Hydrogen sulfide (H2S) exists in a wide range of places like natural gas processing plants, refineries, rubber products plants, pulp mills, tunnels, sewers, sewage ponds, biogas digesters, etc. Therefore, it is really necessary to detect H2S gas concentration before the operations in the above-mentioned places.

ATO offers you fixed and portable hydrogen sulfide gas detector. Whether selecting portable or fixed H2S detector should be based on the operating environment. The measure range should also be chosen according to the site conditions, so as to meet the different use requirements. Thus, even in the unfavorable working conditions, the detector can also detect harmful gases and promptly give an alarm to the staff.

Methyl bromide is an organic compound with the chemical formula CH3Br, which is mainly used as a pesticide, fumigant, refrigerant and solvent, and can also be used in organic synthesis.This video will mainly use methyl bromide and CH3Br as examples to introduce the detection of their concentrations.

How to Detect Hydrogen Sulfide Concentration in the Toilet

Hydrogen sulfide is a flammable acidic gas that smells like rotten eggs at low concentrations and is very toxic. In actual operation, it is necessary to ensure that the detection equipment or method used can accurately measure the concentration of hydrogen sulfide, and pay attention to safety issues during operation to avoid hydrogen sulfide poisoning.
