A brief discussion on the desulfurization and whitening processes in desulfurization towers
Thread Content
Gentleman experts, the battle to defend ** against the current threats has now officially begun. Today, the emissions from thermal power plants, steel mills, and other such facilities far exceed the established standards. I would appreciate it if those with expertise could share any good suggestions or ideas regarding flue gas whitening.
In addition to equipment modification, additives can also be added to reduce the opacity of the flue gas. The opacity can be reduced from the original 30-40% to below 10%.
Desulfurization tower slurry heat exchanger – Flue gas temperature rise and whitening removal
To be honest, flue gas whitening is a wasteful effort that costs a lot of money. It’s not like desulfurization and denitration, which can reduce emission levels below the specified standards and thus have a significant positive impact on the environment. Whitening, on the other hand, does not achieve such results; it merely converts saturated flue gas into unsaturated flue gas. The amount of water vapor remains the same, and aside from the disappearance of the white mist, nothing else changes. It is only necessary in special situations, such as airports, hospitals, and urban areas. But why would you remove your contact lenses in chemical plants, petrochemical plants, or power plants? Personal opinion; please don’t criticize if you disagree
Indeed, but the purpose of whitening in policies nowadays is visual whitening.
Not entirely; it depends on the technical approach. Some methods involve raising the temperature to remove whiteness, which is pure waste. But condensing reheating is still the right approach; it’s just that the investment required for it is high
In the gas-heat exchanger, the gas becomes clean flue gas after condensation, and is then warmed before being released
Think about where the fog comes from – from the north to the south, it creates a misty atmosphere. The dry or semi-dry processing methods are recommended; the choice should be based on the specific project, as these methods can help address issues related to flue gas and wastewater
You make a good point. What I mean is that the practice of whitening should not be overused, otherwise it will lead to increased costs for enterprises and energy waste. It’s meaningless
I have completed the design for flue gas whitening for 1.5 million square meters, and the equipment is currently under production. Anyway, we can only carry out orders.
