May I ask the experts whether such start-up and shutdown procedures in sulfur recovery are commonly used?

Thread Content

During the furnace heating-up period, the flue gas from the furnace enters the alkali scrubber directly； During the heating up of the converter, the flue gas enters the flue gas incinerator from the exhaust liquid separation tank, is incinerated there, and then proceeds to the alkali scrubber ； During the pre-sulfidization of the catalyst in the hydrogenation reactor, the ratio of the analyzer is adjusted to control the hydrogen sulfide content in the process gas; the process gas passes through the quench tower, then to the flue gas furnace for combustion, and finally to the alkali scrubber ； During the sulfur blowing in the shutdown system and the catalyst deactivation in the hydrogenation reactor, the exhaust gas from the shutdown process passes through the quench tower, then to the exhaust gas furnace for combustion, and finally to the alkali scrubber.
