摘要:
以磷石膏为原料,利用其与碳酸铵的反应,制备出硫酸铵,并研究了硫酸铵溶液的结晶方法.考查了物料比、反应温度、反应时间、搅拌速度和液固比等因素对磷石膏中硫酸钙转化率的影响.在物料比n(CO2-3)/n(SO2-4)为1.15,50 ℃,120 min,搅拌器转速100 r/min,液固比为51 mL/g时,磷石膏中硫酸钙转化率可达98.68%.以无水乙醇为溶析剂,从硫酸铵溶液中结晶出硫酸铵,结果表明,结晶温度和硫酸根离子浓度对结晶率影响显著,适宜的结晶温度为25 ℃,硫酸根浓度越高,结晶率越高.
Abstract:
The production of (NH4)2SO4 from phosphogypsum and (NH4)2CO3 has been investigated. The factors affecting the conversion of phosphogypsum to (NH4)2SO4, such as (NH4)2CO3 to phosphogypsum ratio, reaction temperature, reaction time, stripping speed and liquid to solid ratio were studied. The optimum reaction conditions obtained at (NH4)2CO3 to phosphogypsum ratio 1.15, 50 ℃, reaction time 120 min, stripping speed 150 r/min and liquid to solid ration 51. The maximum conversion of phosphogypsum to (NH4)2SO4 obtained under these conditions was 98.68%. A new crystallization method of (NH4)2SO4 was proposed, and the main factors affecting crystallization rate such as crystallization temperature and concentration of sulfate ion have been investigated. Results indicated that temperature and concentration of sulfate ion have obvious effects on crystallization rate of (NH4)2SO4. Suitable temperature was 25 ℃, and the higher the concentration of sulfate ion, the higher the crystallization rate of (NH4)2SO4.
