Dry desulfurization
Thread Content
I would like to ask which is more cost-effective in dry desulfurization: zinc oxide desulfurizers or the current iron-manganese desulfurizers. Iron-manganese desulfurizers require heating for reduction, but they are cheaper； Zinc oxide is expensive, but it can be used for a long time without the need for heating or reduction; please share your opinions
Both are needed; zinc oxide is used for filtration, and normal-temperature zinc oxide is also required before it enters the synthesis tower
Zinc oxide is a bit more effective, but it’s relatively expensive; it has a high sulfur capacity, offering good desulfurization results. It can be used directly without the need for reduction, and no passivation is required when replacing it
