Is the quenching wastewater in the coking workshop acidic or alkaline?
Thread Content
In traditional wet quenching of coke, is the quenching wastewater weakly acidic? After all, the lining of the coking tower is made entirely of clay bricks or cylinder bricks, which are acid-resistant bricks ； But if the remaining ammonia-vaporizing wastewater from the coking plant is mixed into the quenching water, wouldn’t it become basically weakly alkaline? The coke produced after quenching with water treated with ammonia vapor generally has white marks on it
Isn’t the wastewater used for dust suppression the water that has been treated? A friend encountered white substances on the coke after desulfurization
Friends who have actually measured the pH of quenching water are asked to share their results
