Potassium nitrate is produced by contacting nitric acid with a potassium loaded strong cationic exchange resin. In a preferred embodiment, a solution of potassium nitrate and dilute nitric acid is produced in a continuous liquid solid contacting apparatus. The preferred apparatus is formed of a plurality of resin filled chambers which rotate in and out of periodic fluid communication with

Potassium nitrate from nitric acid and potassium chloride

This study was concerned with the development of a process for the production of potassium nitrate for use as a fertilizer material. The process uses KC1 and 60% HNO3 as the starting materials and the intended co-product is Cl2. From information in the literature it was decided to react the KC1 directly with HNO3 simply by mixing the

Potassium nitrate KNO3

Potassium nitrate has been used in a dentifrice or gel to alleviate dentinal hypersensitivity. The aim of this study was to compare a 3% potassium nitrate/0.2% sodium fluoride mouthwash with a 0.2% sodium fluoride control mouthwash in a 6-week double-blind study. Fifty subjects were evaluated using 2 tactile methods and cold air sensitivity (dental air syringe), along with subjective

Study on the production process of potassium chloride

The production of potassium nitrate has been included in the development plan of China’s chemical fertilizer production. 2.1 complex decomposition method (conversion method) the traditional production of potassium nitrate, sodium nitrate method, that is, KNO3+NaCl KCl+NaNO3 (10) due to raw material sodium nitrate prices make the method into

Analysis of potassium nitrate purification with recovery

· Ion exchange nitric acid is passed through cationic exchange resin loaded with potassium leading to the production of potassium nitrate (Eq. ). Potassium hydroxide (KOH) solution is added to neutralize unreacted nitric acid (0.5% by weight) subsequently producing pure potassium nitrate (Nagarale et al., 2006). (5) H N O 3 + R K → H R + K

Enhancement of Molten Nitrate Thermal Properties by

The molten nitrate salt eutectic consisted of sodium nitrate (NaNO3) and potassium nitrate (KNO3) at compns. of 60% and 40% by wt. A modulated differential scanning calorimeter (MDSC) was employed to measure the sp. heat capacity of the pure molten salt eutectic and the nanomaterials (pure molten salt eutectic mixed with nanoparticles).

Potassium Magnesium Sulfate Production. As mentioned, potassium magnesium sulfate occurs naturally as the mineral langbeinite, and can serve as a source of SOP when magnesium is removed. SOPM can be processed into powder, crystals, compaction granules, or rounded granules. Potassium Nitrate (KNO 3)

PHASE

The level of potassium nitrate solution dosed was equivalent to 3.5 mol % of potassium nitrate present in the final prill product. The dosing (tie-in) point for the potassium nitrate solution was into a process condensate line, which is located immediately prior to (and then flows directly to) the neutralizer.
