  • Manufacturing system of electronic-grade ammonia solution
    Patent number: 10501329
    Abstract: A manufacturing system of an electronic-grade ammonia solution comprises: a mixing tank to mix an unsaturated ammonia aqueous solution and alkali to obtain a mixing solution; a stripping unit, disposes downstream the mixing tank and comprises a heat exchanger to heat the mixing solution, and a stripping column to mix a nitrogen gas and the heated mixing solution to obtain a mixing gas; a first absorption unit, disposes downstream the stripping unit and comprises a first condensation unit to cool down the mixing gas, and a first absorption column to mix a saturated ammonia aqueous solution and the cooled mixing gas to obtain a purge gas; and a second absorption unit, disposes downstream the first absorption unit and comprises a second condensation unit to cool down a DI water, and a second absorption column to mix the cooled DI water and the purge gas to obtain electronic-grade ammonia solution.
