1. How to determine whether you smell natural gas or biogas?
To distinguish between natural gas and biogas, the following methods can be used:
1. Detection of ethane. The main component of natural gas is methane, but it usually contains hydrocarbons such as ethane and propane.
; And biogas is produced by the fermentation of organic matter (such as feces and straw), mainly composed of methane and carbon dioxide, with almost no ethane. If ethane is detected through professional equipment such as portable intelligent ethane identification devices and gas industry specific gas chromatographs PGC, it can be confirmed that the gas is natural gas2. Odor Zheng code assists in determining that natural gas will add "odorants" (such as thiol compounds) during transportation, giving it a pungent odor similar to rotten eggs or vegetables. However, biogas itself does not have a special odor. If no artificial odor agent is added, there may be no obvious odor when turning. However, it should be noted that odor detection may be affected by environmental interference (such as masking other odors), and some biogas projects may add odorants to enhance safety. Therefore, relying solely on odor cannot fully distinguish. Other auxiliary detection methods include hydrogen content detection: During biogas fermentation, a small amount of hydrogen may be produced, while the hydrogen content in natural gas is extremely low. The hydrogen concentration can be detected by a hydrogen selective gas sensor to assist in determining the gas source. Gas pressure and flow detection: Natural gas usually comes from underground gas fields and has high pressure when transported through pipelines; Biogas is mostly produced in biogas dig
2. Which soaking medium can be used to disinfect the flowmeter?
For disinfection of flow meters, 75% medical alcohol or 500mg/L chlorine containing disinfectant solution should be preferred for soaking, and specific matching should be made according to the material.. Understanding the material of the flowmeter is key, as metal materials are sensitive to corrosion, while plastic components may be affected by organic solvents. Before processing, first confirm the durability instructions in the equipment manual. Industrial grade flow meters usually have strong durability, but precision medical sensors may require special treatment. 1. Common applicable soaking medium: • 75% alcohol: suitable for corrosion-resistant parts such as metal and glass. Soak for 10-30 minutes and rinse with clean water to avoid residual effects on the accuracy of quick warning. Chlorine containing disinfectant (such as 84 dilution): soaked in a 1:100 ratio for 30 minutes, it has a high virus and bacterial inactivation rate, but aluminum components should be
