How to reduce the amount of alkali solution used in catalytic flue gas desulfurization
When the flue gas meets the requirements, try to reduce the amount of alkaline solution used.
Appropriately increase the liquid level in the desulfurization scrubber, control the regeneration coking temperature, and raise the temperature of the catalyst bed in the regenerator within the operational range.
It’s not possible to replace the raw materials; the sulfur content in our raw materials is generally above 1.0%
If the raw materials cannot be optimized, then the sulfur distribution is essentially fixed, which means that the amount of sulfur dioxide in the flue gas remains constant. As a result, it’s difficult to change the amount of alkali solution required. However, if there is some flexibility in the emission standards, the alkali consumption can be controlled by lowering the pH of the slurry; but this approach presents corrosion issues. Additionally, efforts should be made to reduce the amount of wastewater discharged, although this has a relatively minor impact on alkali consumption.
This is the law of conservation; many things cannot be changed just because you want them to be!
The raw materials remain unchanged, and the catalyst remains unchanged. This is difficult, right?
A vulcanization transfer agent can reduce the amount of alkali solution needed – you might want to give it a try!
By controlling the amount added, less desulfurizer is needed! It needs to be calculated specifically!
