The chimney of the sulfur recovery unit is emitting large amounts of smoke due to its shutdown
Thread Content
What will happen if, during the shutdown of the CLAUS sulfur recovery unit, the exhaust gas from the catcher is diverted through the exhaust gas bypass line, resulting in heavy smoke emission from the chimney? How should it be handled?
Isn’t shutting down the plant meant to remove sulfur? Be more specific – did the reactor catch fire?
After the exhaust gases are routed through the crossover line, large amounts of substances containing SO2, H2S, and gaseous sulfur enter the incinerator directly. Upon combustion, these substances turn into SO2, which is then emitted through the chimney, resulting in smoke emission from the chimney. This is also the problem that typically arises when sulfur recovery units have to be shut down. The question is how to coordinate things properly in order to minimize the time during which the chimney emits smoke.
1. Changing to the exhaust gas bypass line resulted in a reduced recovery rate; 2. The desulfurization process was not thorough. These factors led to a large amount of hydrogen sulfide and sulfur dioxide going into the incinerator.
During the shutdown of the device, there’s no need to consider the recovery rate, right? !
I mean the smoking occurs because of the reduced sulfur yield
I have a gentle question: what exactly does it mean to change to cross-wiring? ! I look forward to your careful guidance
A bypass that goes directly from the exhaust gas liquid removal tank to the exhaust gas incinerator for combustion, with the exhaust gas purification unit being bypassed, leading to emissions through the chimney.
It seems like some amateurs are discussing on the forum, which is quite frustrating
