In various links such as oil extraction, refining, storage and transportation, there may be risks of leakage of various harmful and flammable and explosive gases. For example, in the process of oil and gas field extraction, the detector can monitor the concentration of combustible and toxic gases in real time to ensure the safety of workers; in the refining process, the detector can detect the gas composition in key equipment such as reactors to prevent explosions and poisoning accidents.
Main pollutants in the underground operation process: Environmental pollutants generated in the underground operation process mainly come from acidification, fracturing, well washing and other operations. During the fracturing operation, a large amount of fracturing fluid will be discharged from the wellbore. The fracturing fluid contains a variety of organic and inorganic chemical additives, which will produce sewage and sludge containing chemical additives; the ground high-pressure pump group will produce vibration and noise pollution during the fracturing construction process; the high-power diesel engine group will produce smoke emission pollution and noise pollution. During the acidizing process, the acid reacts with sulfur-containing minerals in the formation, which may produce toxic and harmful hydrogen sulfide gas, causing air pollution. As an important industrial field, petrochemical industry involves the production, use and emission of a large number of toxic and harmful gases.
It is particularly important to monitor and detect these harmful gases. Below we will introduce the toxic and harmful multiple gas detector for petrochemical industry.
A. Detection principle The toxic and harmful gas detection instruments for petrochemical industry use advanced sensing technology and chemical analysis principles to accurately monitor the concentration of toxic gases in the air in real time, such as carbon monoxide, hydrogen sulfide, ammonia, formaldehyde, etc.
B. Toxic and harmful gas detection instruments are usually used in petrochemical plants, chemical workshops, oil depots, oil field operations, pipeline transportation, oil and gas exploration and other places to ensure the safety of the working environment and the smooth progress of production.
1. Types of harmful gases in the well
In the well operation, you may encounter a variety of harmful gases, including carbon monoxide, carbon dioxide, hydrogen sulfide, etc. Among them, carbon monoxide and hydrogen sulfide are the two most common and most harmful. There are various reasons for the generation of these gases. For example, these harmful gases may be produced during the mining of mineral resources such as coal and oil.
2. Hazards of harmful gases
A. Carbon monoxide: High concentrations of carbon monoxide can suffocate people, affect the normal function of the blood and nervous system, and even be fatal in severe cases.
B. Carbon dioxide: High concentrations of carbon dioxide can make people feel suffocated, but are usually not fatal. Long-term exposure to carbon dioxide can make people feel tired, have headaches, and dizzy.
C. Hydrogen sulfide: Hydrogen sulfide can cause a strong and unpleasant odor. At high concentrations, it can irritate the eyes and respiratory tract and even be fatal.
The presence of these harmful gases can also affect the breathing and work efficiency of underground workers and threaten the lives of workers. Therefore, necessary ventilation and testing are required before underground operations to ensure the safety of the air quality in the working environment.
3. How to prevent and deal with harmful gases
A. Ventilation: When working underground, good ventilation is required to reduce the concentration of harmful gases.
B. Detection: Use professional gas detection instruments to regularly detect the air quality underground to ensure that the concentration of harmful gases is within a safe range.
C. Wear protective equipment: Underground workers need to wear professional protective equipment, such as gas masks, protective clothing, etc., to protect their own safety.
D. Emergency treatment: If harmful gas leaks or concentrations are too high, emergency treatment measures should be taken immediately, such as ventilation, evacuation of the affected area, etc.
E. Regular training: Enterprises should regularly train underground workers on harmful gas-related knowledge to improve their safety awareness and response capabilities.
