Help! Problems with online oxygen detection for gas
Thread Content
I would like to ask fellow sailors for advice. Our factory’s gas production facility has a small scale – it produces around 6,000 cubic meters of gas per hour. There are no gas storage tanks, nor are any electrostatic precipitators in use. At present, manual sampling is carried out hourly to analyze the gas composition; however, some people suggest installing an online oxygen content detector. What are the specific requirements for such an online oxygen monitoring system? Is it necessary to install it? What is better to use?
You need to first specify the process conditions, such as temperature, pressure, composition, etc., as well as the range of values. Generally, a pretreatment system is required; infrared oxygen measurement is a well-established technique in coal gasification
Thank you for the guidance! The outlet pressure of the gas generator is around 1 kilopascal, with a temperature of 4–5 hundred degrees. After passing through the double vertical pipes, washing tower, conveyor, and droplet catcher, the temperature drops to around 40 degrees while the pressure remains at 8 kilopascals. Coke is used as the main fuel; the amount of tar produced is low, but there is a significant amount of dust!
2# coalboy: Huh? How can infrared be used to measure oxygen? For this operating condition, magnetic mechanical paramagnetic oxygen is the best choice
The oxygen content in gas is part of safety monitoring, and it is advisable to use an online analysis system for this purpose.
Sorry, it should be a magnetometric oxygen analyzer. Here are the parameters for the SIEMENS oxygen analyzer Oxymat 6: Sample gas pressure: 500–3000 hPa (7–42 psig); Sample gas flow rate: 18–60 L/h; Sample gas temperature: 0–50 degrees; Sample gas humidity:
It’s better to install a device that checks the oxygen level first, as that is safer
Oh! Thank you all for your guidance. The day before yesterday, someone showed me a laser; those that are generally usable cost around 200,000! I don’t know; how much is the magnetic one? Is it easy to maintain?

The laser gas analyzer from Focus Technology should be fine; its advantage is that sample preprocessing is simple, or even not required at all. A magnetic oxygen analyzer can also be used, but the sample requires proper preprocessing, and maintenance costs may be high. Choosing an online analyzer is the only sensible option; it’s necessary to conduct thorough research and not rely on what the instrument manufacturers say, especially those salespeople who have no understanding of the technology or its applications.
