Alkali consumption for flue gas desulfurization in catalytic units
Thread Content
The sulfur content in our raw material is 1.2%. In the regenerator, the proportion of catalyst used is 1.5%, along with a sulfur transfer agent; the amount of alkali required for flue gas desulfurization is 12.5 Kg per ton of raw material. What is the amount of alkali needed for flue gas desulfurization in your catalytic unit?
Learning* about it; this issue is under consideration.
The properties of the raw materials, the regeneration temperature, the amount of combustion aids added, etc., all have an impact on the sulfur content in the flue gases.
There are many factors that affect the amount of alkali solution required; in terms of regeneration methods, complete regeneration of the sulfur transfer agent yields better desulfurization results than incomplete regeneration. The sulfur content of the raw material and the properties of the sulfur transfer agent determine the degree of desulfurization, which in turn determines the amount of alkali solution required. It’s indeed not very useful as a reference
Mark the conditions and write down the alkali consumption of each device; it can serve as a reference for everyone. Regeneration method: Sulfur content in the raw material:
1.2 million tons of catalysis, complete regeneration; the sulfur content in the raw material is around 0.4%, the content of sulfur transfer agents is about 2.3%, the consumption of alkaline solution is 70–100 kg/h, and the sulfur oxide level at the inlet is 100–150. 4.8 million tons are not fully regenerated; the sulfur content of the raw material is around 0.35, the content of sulfur transfer agents is about 3%, and the consumption of alkaline solution is 2.2 tons per hour.
It’s a great topic; I’m curious about what happens without a vulcanization transfer agent. Correlation between the sulfur content in raw materials and sulfur oxides in flue gas
Once, the sulfur content in the difficult-to-treat raw material was 1.7%; no matter what amount of flue gas was used for flue gas desulfurization, it was not possible to reduce the sulfur content, and it exceeded the limit by 150 mg
Which manufacturer’s sulfur transfer agent are you using?
