What are the requirements for the moisture content in the conversion gas for the domestically produced sulfuric acid catalysts S-101 and S-108?
Thread Content
I would like to ask the experts in catalysts a question: Do domestic sulfuric acid catalysts, such as S-101 and S-108, have any requirements regarding the moisture content in the conversion gas? What is the maximum moisture content that can be tolerated if required? If the water content in the converted gas reaches 8%, will it affect the performance and usability of the catalyst? Are there domestic catalysts available for acid production using the wet process? I look forward to your advice! Thank you.
S-101 and S-108 have requirements regarding the moisture content in the converted gas: moisture level < 0.10 g/Nm3. There are domestic catalysts used in the wet acid production process: the NWS-1 type developed by the Research Institute of Nanhua Group
The moisture level is generally kept below 0.10 g/Nm3; high moisture levels have a significant impact on the catalyst, accelerating its pulverization, increasing the resistance in the converter, and reducing the conversion efficiency of the conversion system.
Reply to 2# txglyl: Hello, what is the Chinese term for the unit 0.10 g/Nm3? What is the relationship with g/m3?
The water content in each standard cubic meter of air is less than 0.1 grams.
Wet acid production refers to the use of hydrogen sulfide as the feed gas, with water present in the conversion products, right? What is the relationship with the high moisture content of your feed gas: L
Reply to 7# 20012655: That’s right; it refers to gaseous water, not liquid water. The temperature at which SO2 is converted to gas is as high as 400 degrees Celsius, so there can be no liquid water present. My question is: does 8% water vapor content have an impact on the performance and lifespan of S101/108?
