摘要
介绍云天化云峰分公司产能为10 kt/a工业级磷酸一铵装置的脱硫磷酸生产,阐述了湿法磷酸脱硫原理及工艺流程、脱硫料浆沉降工艺、化学沉淀法以及控制要点,指出用浓磷酸生产脱硫磷酸优于用稀磷酸生产脱硫磷酸。
The operation of the desulfurized phosphoric acid for the 10 kt / a industrial grade MAP from Yunfeng Branch of Yuntianhua International Chemical Co.,Ltd. is described,and the desulfurization principles and process flow of wet process phosphoric acid,desulfurization slurry settlement process,chemical settlement method and control points are outlined,and it is pointed out that by using concentrated phosphoric acid to produce desulfurized phosphoric acid,it is better than producing desulfurized phosphoric acid with dilute phosphoric acid.
