Analysis of the pretreatment system design for analysis cabins (coal chemical syngas analysis)
Thread Content
In coal chemical applications, it is generally necessary to analyze the contents of CO, CO2, CH4, H2, etc., in syngas. However, the syngas medium is quite dirty and may also contain water; therefore, a pretreatment system is very important. In our company, the pretreatment pipelines often get clogged and water seeps in. I would like to ask if Haiyou has any good pretreatment solutions that it could share with us.
Reply to 1# jack19842006: Does \"syngas\" refer to gas production? What kind of furnace is it, and who is responsible for the preprocessing?
For specific questions, analysis should be conducted; different analysis subjects require different preprocessing methods, and various manufacturers have different approaches for different analyses. In a broad sense, the preprocessing of analytical instruments starts from the very beginning: the location and direction of the openings in the process pipelines, the selection and proper insertion direction of sampling tubes, the choice of sampling valves, as well as the radiation length, inclination angle of the sampling tubes and whether they are equipped with heating systems. All the way up to the conventional preprocessing devices found in the analysis laboratory, these all fall under the category of analytical instrument preprocessing systems. The selection and design of such systems are quite complex, so it’s not possible to simply state which one is the best.
The poster is referring to coal chemical industry, specifically coal gasification projects. In China, the Texaco process is generally used to convert coal into gas, which is then used to produce downstream products such as olefins and acetic acid. In this process, infrared gas analyzers and moisture analyzers are employed to measure the levels of CO, CO2, CH4, H2, etc. I have a pretreatment plan; you can leave an email address and I’ll send it to you for your reference.
This requires not restricting the budget during the selection and bidding process, and proper design preprocessing is essential. Many have been successful domestically, while many others have encountered problems.
The gas quality at the vaporization outlet is relatively dirty; therefore, cooling and depressurization in the preceding stages are very important. Hangzhou Juguang Technology has seen successful applications of its aerospace furnaces in western Shandong, as well as those from Jinchi in the Texaco project; it is recommended that you consult them.

For this type of gasification furnace, the first issue to address is that of water; it is necessary to remove the large amount of water present in the furnace. It seems like your preprocessing isn’t done properly!
