Total sulfur in exhaust gas and flue gas data at the back of the absorption tower
Thread Content
Dear sea industry professionals, I would like to ask what is the typical value of total sulfur measured after the absorption tower in sulfur recovery units? What are the corresponding flue gas data? I would also appreciate your valuable advice. . . .

After the exhaust gas absorption tower, the sulfur content is generally around 960 mg/m3; sometimes it meets the standards and sometimes it does not. Currently, the required sulfur content in exhaust gases is 500 mg/m3, and in most cases this level is not achieved. Therefore, additional exhaust gas absorption systems (ammonia absorption after alkaline washing) are needed to ensure that the emissions meet the specified standards.
The sulfur dioxide content in the exhaust gas from our absorbers is quite low; it should be no more than 100, with emissions generally kept around 50.
