How do you handle ferrous sulfide that is generated during shutdown maintenance?
Put them all together in an iron barrel, then cover it with a lid. Assign people to conduct regular inspections at set times and places, and provide fire-fighting equipment in the vicinity. If temperatures are high in summer, water can be sprayed to cool them down. Finally, it should be handled by a specialized department; generally, it seems to need to be buried underground
There are not many preventive measures in practical applications; basically, there are three: the first is passivation, which involves preparing a potassium permanganate passivating agent and using a circulation system, immersion, or spraying method； The second is the distillation tower; depending on the effectiveness of the corrosion inhibitor, either the iron ion content in the acidic water increases or the distillation time is reduced ； Third is water flushing: whether it is a tower or a heat exchanger, fresh water should be used to flush it immediately once the manhole or cover is opened ；
