GENERATOR ACID PURIFICATION™ (GAP)
To produce chlorine dioxide, an excess of sulfuric acid is required along with a reducing agent. The residual acid consists of a mixture of both sulfuric acid and sodium sulfate. Typically, most of the residual acid is sent to the sewer where lime is used for neutralization. Alternatively, the acid can be returned to the mill’s recovery cycle.
Noram’s GAP™ system separates sodium sulfate and sulfuric acid to recover the residual acid. The chloride present in the sesquisulfate accompanies the acid and is removed from the recycling process.
