Magnesium nitrate dilute solution has a high nitrate content
Thread Content
During the production of concentrated nitric acid, the magnesium content in dilute nitric acid is high; how can this be effectively addressed?
High nitrate content: it shortens the corrosion cycle of equipment and is not conducive to long-term operation; it is necessary to control the liquid level of the heater, adjust the reflux ratio appropriately, and increase the steam pressure in order to concentrate dilute magnesium and remove nitrogen oxides… High nitrate content also leads to a shorter corrosion cycle of the equipment, which is unfavorable for long-term production
