How to remove the irritating smell of polyferric sulfate

During spray drying and dissolving, the produced polyferric sulfate will produce strong irritating smell, which will make the whole plant have irritating smell. It is not only harmful to the environment, but also harmful to human body. Operators must wear gas masks to continue their work. How can the irritating smell of PFS be removed?

To solve the irritating odor caused by polyferric sulfate, we need to know the cause of the irritating odor. Through experimental analysis, one case is produced by solid polyferric sulfate in the spray drying stage, the other case is the irritating odor produced during the dissolution of solid polyferric sulfate. The gas generated under these two conditions is highly irritating. Preliminary judgment is that the residual oxidant sodium chlorate is produced after heating in the production of liquid polyferric sulfate. The key to odor removal is to control the production process of liquid polyferric sulfate.

The better deodorization scheme is to use hydrogen peroxide as oxidant to produce polyferric sulfate in the process of direct oxidation. The liquid product quality meets the standard. Moreover, due to the reduction of the amount of oxidant, the discharged irritating gas is reduced, which solves the unpleasant odor problem of polyferric sulfate in the production process.

Therefore, the key to remove odor from PAS is to control the dosage proportion of agent properly and reduce it by changing the proportion of production method. It can not only deodorize but also reduce production cost, thus achieving the desired effect.
