Process for reducing flue gas parameters in sulfur recovery
Thread Content
Our plant’s sulfur recovery unit uses the Claus process with exhaust gas absorption; the current emission limit for sulfur dioxide is 400 mg/m3, and there are plans to reduce this limit to below 50. Are there any cases of successful modifications, and if so, how were they carried out? Thank you
As of July 1, 2017, the GB 31570-2015 standards for atmospheric pollutant emissions must be implemented; under these standards, the allowable mass concentration of SO2 emissions has been reduced from 960 mg/m3 to 100 mg/m3 (equivalent to an oxygen content of 3% on a dry basis).
There are various methods to ensure that exhaust emissions meet regulatory standards; the two most commonly used methods at present are: 1. Catalytic oxidation process 2. Recirculating alkaline washing process. They can be used independently or in combination.
The number of new installations in special areas is 50. Generally, it’s 100 for new constructions. The sulfur recovery system we have modified can achieve compliant emissions. You need to contact me
