Exhaust treatment
Thread Content
Power plant exhaust contains gases such as sulfur dioxide and carbon dioxide. We are considering using methanol to absorb these two gases; we’re not sure if it will be effective. PS (Methanol is originally used to treat hydrogen sulfide and carbon dioxide.)
The absorption effect is good only at low temperatures and high pressures. Additionally, has it been considered that even if the absorption meets the requirements, the methanol content in the exhaust gases might still be above the limit?
Lack of initiative can lead to secondary pollution.

Could you briefly explain secondary pollution? Is it caused by methanol being carried away by gases?
Is it because the methanol is carried away by the gas?

Same question: theoretically, when the pressure and temperature meet the requirements, complete separation is possible, right?:o
The low-temperature methanol washing unit is exactly designed for this purpose; how could it cause secondary pollution?
It doesn’t work; methanol absorbs hydrogen sulfide but not sulfur dioxide.
