Gas detectors are mainly used in industries and gases that need to be detected in various fields
Gas detectors are instruments and equipment for detecting gas concentrations. The detection of flammable gases and toxic and harmful gases has been put into use in various industries. So which industries mainly use gas detectors? What are the gases detected by gas detectors in each industry?
1. Oil & Gas
The oil and gas industry encompasses a variety of activities ranging from onshore and offshore exploration to the production of oil and gas to its transportation, storage and refining. The large quantities of highly flammable hydrocarbon gases involved are a serious explosion hazard, and in addition, toxic gases such as hydrogen sulfide are often present.
2. Semiconductor manufacturing
The manufacture of semiconductor materials involves the use of highly toxic substances and flammable gases. Phosphorus, arsenic, boron and gallium are often used as additives. Hydrogen is not only used as a reactant, but is often used as a carrier gas for reducing air. Pickling and cleaning gases include NF3 and other perfluorinated compounds.
3. Chemical device
Chemical plants are probably one of the largest users of gas detection equipment. During their production, they are commonly used, or as by-products, to generate a wide variety of flammable and toxic gases.
4. Power station
Traditionally, coal and oil have been used as the main fuels for power stations. In Europe and the United States, the fuel of most power stations has been converted to natural gas. At present, the gases that need to be detected in coal power stations: flammable gases: natural gas, hydrogen; toxic gases: carbon monoxide, SOx, NOx lack of oxygen
5. Wastewater treatment device
Wastewater treatment plants are common in many cities and towns. Sewage naturally emits methane and hydrogen sulfide. The "rotten egg" smell of hydrogen sulfide gas can be detected by the nose even at as little as 0.1ppm, thereby attracting attention.
6. Boiler room
Boiler rooms come in many shapes and sizes. Smaller buildings may use a single boiler, while larger buildings often have large boiler rooms containing several large boilers. • Poorly maintained boilers emit carbon monoxide.
7. Hospital
Hospitals may work with many different flammable and toxic substances, especially in their laboratories. In addition, there are many large-scale hospitals that use on-site equipment power supplies and backup power stations. Main application places: laboratory/cooling device/boiler room, etc. Common gases are: flammable: methane, hydrogen
8. Tunnel/parking lot
In vehicle tunnels and closed car parks, monitoring of toxic gases in exhaust gases is required. Ventilation fans are monitored and controlled in modern tunnels and car parks. The accumulation of natural gas also needs to be monitored in the tunnel. It is necessary to install a gas detector for on-site concentration detection. When the concentration exceeds the standard, an audible and visual alarm will be issued to remind the closed place to carry out ventilation operations and evacuate the scene in time.
