Water balance of the ammonium sulfate production section
Thread Content
“The moisture in the saturator is mainly introduced by gas and ammonia vapor; the rest comes from sulfuric acid, as well as the wash water from the centrifuge, saturator, and acid remover. To maintain the water balance of the saturator and prevent the mother liquor from being diluted, which could disrupt normal operation, all of this additional water must be carried out of the saturator by the gas. ”So what is the state of the gas that comes out of the saturator? Saturated? Unsaturated? Supersaturated?
Of course it’s saturated; in other words, it’s necessary to calculate the gas outlet temperature that needs to be controlled based on the amount of water supplied, so as to ensure that the gas carries away sufficient moisture
