Discussion on qualified methods for monitoring flue gas in sulfur recovery
Thread Content
In the online monitoring of flue gas in sulfur recovery processes, SO2 levels occasionally exceed the permissible limits. Apart from adjusting the process operations, what other effective measures can be taken to meet environmental compliance requirements? (Measures must be legal.) I would greatly appreciate any advice you can offer! http://bbs.hcbbs.com/thread-1797751-1-1.html
Add a tail gas scrubbing device, such as using ammonia water for absorption.
Where process conditions permit, increasing the oxygen content can effectively reduce sulfur dioxide emissions. Additionally, it is necessary to regularly purge the sampling pipes.
It is possible to introduce a certain amount of fuel gas (into the tail gas incinerator) to dilute the flue gas; this will cause a decrease in various related parameters. However, it would be better to add desulfurization equipment instead
Apart from optimizing the process, there’s no other solution
