Applications of Oxygen Analyzers in Various Industries

An oxygen analyzer is an instrument designed to measure the oxygen content in gases. With its precise detection capability, it is widely used in numerous industries where strict control or real-time monitoring of oxygen concentration is required. Here is a detailed breakdown of its applications:

1.Chemical Industry

Production Process Control：Many reactions in chemical production are extremely sensitive to oxygen concentration. For example, in the ammonia synthesis process, oxygen content must be strictly controlled to prevent hazards such as explosions, while ensuring the smooth progress of reactions and product quality.

Gas Production and Processing：During the production and purification of gases like oxygen and nitrogen, oxygen analyzers are used to detect gas purity, ensuring that products meet relevant standards and application requirements.

Catalyst Activation and Regeneration：The activation and regeneration of certain catalysts require a specific oxygen atmosphere. Oxygen analyzers can monitor oxygen concentration in real time to optimize reaction conditions.

2.Metallurgical Industry

Iron and Steel Smelting：Oxygen content inside the furnace needs to be controlled during iron and steel smelting to ensure the normal progress of redox reactions in molten iron, thereby improving steel quality and output. For instance, in converter steelmaking, oxygen analyzers are used to monitor oxygen flow and concentration, enabling precise control of the oxygen-blowing process.

Non-ferrous Metal Smelting：The smelting of non-ferrous metals such as copper and aluminum also requires monitoring and controlling the oxygen concentration in the furnace to guarantee smelting efficiency and metal purity.

Metal Heat Treatment：Processes like annealing and quenching in metal heat treatment need to be carried out in a specific atmosphere. Oxygen analyzers are used to monitor the oxygen content in the atmosphere, ensuring heat treatment quality.

3.Environmental Protection Industry

Wastewater Treatment：The aerobic treatment process in wastewater treatment requires an adequate oxygen supply. Oxygen analyzers are used to monitor the dissolved oxygen concentration in aeration tanks, so as to adjust aeration intensity and ensure wastewater treatment efficiency.

Waste Gas Treatment：For the treatment of industrial waste gas, such as the combustion of organic waste gas, oxygen content during combustion must be controlled to ensure complete combustion of waste gas and reduce pollutant emissions.

Environmental Monitoring：Oxygen analyzers can be used to monitor oxygen concentration in the atmosphere and dissolved oxygen content in water bodies, providing data support for environmental monitoring and protection.

4.Medical Industry

Medical Gas Supply：Oxygen is an essential medical gas in hospitals, used for oxygen therapy of patients and anesthesia in operating rooms. Oxygen analyzers are used to monitor the purity of medical oxygen, ensuring compliance with medical standards.

Intensive Care：In intensive care units, real-time monitoring of oxygen concentration in the gas inhaled by patients is required to adjust oxygen supply plans and maintain patients' respiratory function.

High-Altitude Medicine：In high-altitude areas, where air pressure is low and oxygen content is scarce, oxygen analyzers can monitor the ambient oxygen concentration, providing a basis for the prevention and treatment of altitude sickness.

5.Food Industry

Food Packaging：To extend the shelf life of food, many products adopt vacuum or nitrogen-filled packaging. Oxygen analyzers are used to detect the oxygen content inside packages, ensuring packaging tightness and food quality.

Food Processing：During food processing, such as baking and frying, oxygen content in the air needs to be controlled to prevent food oxidation and deterioration.

Beverage Production：In beverage production, especially for bottled beverages, oxygen content inside bottles must be controlled to avoid oxidation of beverage ingredients and maintain taste and quality.

6.Electronics Industry

Semiconductor Manufacturing：Semiconductor manufacturing processes need to be conducted in a high-purity inert gas atmosphere. Oxygen analyzers are used to monitor oxygen content in the gas, ensuring semiconductor manufacturing quality.

Electronic Component Production：The production of electronic components such as integrated circuits, resistors and capacitors requires controlling the oxygen concentration in the production environment to prevent component oxidation and damage.

Vacuum Coating：Oxygen content in vacuum chambers needs to be controlled during vacuum coating processes to ensure coating quality and performance.

7.Energy Industry

Thermal Power Generation：Oxygen content in boilers needs to be controlled during thermal power generation to ensure full combustion of fuels, improve power generation efficiency and reduce pollutant emissions.

Petrochemical Industry：During oil extraction and processing, oxygen analyzers are used to monitor oxygen content in oil and gas fields to prevent explosions and other hazards. Meanwhile, they help control reaction conditions in the oil refining process.

New Energy Sector：In the research, development and production of new energy technologies such as fuel cells, strict monitoring of oxygen content in gases like hydrogen is required to ensure fuel cell performance and safety.

8.Aerospace Industry

Aero-engines：Oxygen supply needs to be controlled during the combustion process of aero-engines to ensure their normal operation and efficient combustion. Oxygen analyzers can monitor oxygen concentration in combustion chambers.

Spacecraft Environmental Control：The cabin environment of spacecraft needs to maintain an appropriate oxygen concentration to ensure the life safety of astronauts. Oxygen analyzers are used for real-time monitoring of cabin oxygen content and corresponding adjustments.

Rocket Propellants：The combustion of rocket propellants requires a certain amount of oxygen participation. Oxygen analyzers are used to monitor oxygen content in propellants, ensuring the safe launch and operation of rockets.

9.Other Industries

Scientific Research Field：In scientific experiments, oxygen analyzers are used for monitoring and controlling oxygen concentration in various gas reactions and biological culture processes, providing accurate data support for scientific research.

Diving Industry：Divers need to breathe oxygen of a certain concentration during diving. Oxygen analyzers are used to detect the oxygen content in diving cylinders, ensuring divers' safety.

Agricultural Sector：In agricultural greenhouses, oxygen analyzers can monitor the concentrations of carbon dioxide and oxygen to optimize the growth environment of crops and increase yield and quality. In addition, controlling the oxygen content in the storage environment can prevent grain mildew during grain storage.
