Practice has shown that the load on the sulfur treatment unit has a significant impact on flue gas SO2 emissions, beyond what was expected, even when the process parameters appear to be normal. Why is this? Which process conditions have changed due to the load variation? Where lies the bottleneck in controlling the yield?
Factors such as this conversion rate, hydrolysis rate, the capacity of the absorption tower, and the effectiveness of amine solution regeneration can all be potential influencing factors.
Under normal operating conditions, the operational flexibility of sulfur recovery units is typically between 30% and 110%; too low or too high a load can have an impact on environmental performance metrics.
Why is the purity of our sulfur low? How to deal with it?
After analysis, which component has a high content? Logically, the possibility of high mechanical impurities is high. That is mostly things like linings, carbon deposition in the system, catalyst powder, and corrosion products.
It should be tar and dust or something like that
Personal opinion: Catalyst and amine solution absorption are highly dependent on the load. For example, in a reactor: with the same catalyst bed, a lower processing capacity does it mean that the process gas comes into more thorough contact with the catalyst, resulting in a greater degree of reaction?
