Monitoring factors
Methane, non methane total hydrocarbons, and total hydrocarbons
product overview
This instrument adopts catalytic oxidation+FID detection technology combined with the advantages of a hydrogen oxygen generator, and can measure total hydrocarbons, methane, and non methane total hydrocarbons in ambient air and fixed pollution source exhaust gas. The equipment has passed national explosion-proof certification and can be used in explosion-proof areas such as petrochemicals, gas stations, and oil storage tanks. The whole machine weighs ≤ 4.0Kg and is a portable non methane total hydrocarbon equipment that combines safety, explosion prevention, economy, and stability.
Working principle
Catalytic oxidation+FID: Methane inside the catalytic tube is not catalyzed, and non methane total hydrocarbons are catalytically converted into carbon dioxide and water. Only methane reaches the FID detector for detection. Total hydrocarbons and methane are detected successively by FID in the same cycle, and the content of non methane total hydrocarbons is finally calculated by the difference between the total hydrocarbons and methane content.
Electrolysis of water to produce hydrogen and oxygen: Pure water that meets the requirements is sent into the electrolysis cell. After being powered on, the cathode of the electrolysis cell produces hydrogen gas and the anode produces oxygen gas. The two are separated by water and gas, dehumidified by a dryer, and adjusted to the rated pressure through a pressure regulator valve and a regulating valve before being output to the designated pipeline.
