Consultation on the analysis of crude syngas
Thread Content
Syngas is produced via biomass gasification; the temperature in the gasifier is around 1000 degrees, and the pressure is at a negative level of -99.8 KPa. The crude syngas contains tar, dust, and water. (1) How to take samples in a high-temperature, low-pressure gasification furnace? Should online analysis be used or offline analysis after sampling? (2) How to measure the contents of tar, dust, and water in crude syngas? What instruments to use? What is the testing principle? (3) How to remove tar, dust, and water from the crude syngas before it is fed into gas chromatography analysis? What configuration is required for gas chromatography? Could anyone recommend manufacturers of such instruments? Thank you.
Both online analysis and sampling analysis should be available! Online analysis allows for real-time monitoring of the composition of syngas, while sampling analysis is used to verify the accuracy of the online analysis
Reply to 2# sangeshuiyuan: Could the friend on the 2nd floor give some specific suggestions? How to take samples from a high-temperature gasifier? Do you know of any negative pressure sampling equipment? How are tar and dust measured?
