    • A process for synthesizing ammonium sulfate and United States Pharmacopoeia grade sodium bicarbonate. The process allows an energy efficient conversion of precursor sodium sulfate and bicarbonate to ammonium sulfate high grade fertilizer and the pharmaceutical grade sodium bicarbonate by saturation of process brine with sodium sulfate. This step was previously unrecognized in the art, which resulted in prior art methods being ineffectual from engineering, energy and product quality points of view. The present process reintroduces sodium sulfate into the process brine or solution to perpetuate the conversion process in the absence of separation problems and energy expenditures inherent in the prior art techniques.
    • 一种合成硫酸铵和美国药典级碳酸氢钠的方法。 该方法通过用硫酸钠处理盐水饱和,能够将前体硫酸钠和碳酸氢盐能量转化成硫酸铵高级肥料和药物级碳酸氢钠。 此步骤以前在本领域未被认识到,这导致了现有技术方法在工程,能源和产品质量方面无效。 本方法在不存在现有技术中固有的分离问题和能量消耗的情况下,将硫酸钠重新引入到处理盐水或溶液中以使转化过程永久化。
