氟化铵热分解混合气体分离装置及分离方法
By using a mixed gas separation device based on the thermal decomposition of ammonium fluoride, ammonia and hydrogen fluoride are separated using potassium difluoride to generate potassium fluoride complex salts. This solves the safety risks of ammonia and hydrogen fluoride in the nuclear fuel preparation process and achieves safe separation and meets process requirements.
