Abstract:

The principle of laser gas analyzer based ondiode laser absorption spectros copy (DLAS) technology isreviewed. The experimental system and the measured results of this analyzer are presented. The analyzer doesn’tneed sample pre-treatment,and has the advantages of good precision,fast response and low maintenance. The application results of the analyzer for regeneration flue gas measurement of FCC (fluid catalytic cracking) show that it can meet the needs of regeneration flue gas components analysis ofFCC.
