降低氯气处理浓硫酸消耗的探索

Discussion on reducing sulfuric acid consumption in chlorine treatment

总结了影响浓硫酸消耗的因素,包括氯处理工艺流程、入干燥塔氯气温度、入干燥塔浓硫酸温度及纯度等。针对这些因素改造系统,严格控制工艺指标,可使10万t/a烧碱装置对应的氯气处理工序节约浓硫酸500多t。

The factors of influencing sulfuric acid consumption in the process of chlorine treatment are summarized including chlorine treatment process, the inlet temperature of chlorine into the dry tower, the inlet temperature and purity of sulfuric acid into the dry tower. The system is reformed in view of these influencing factors and the process indexes are controlled strictly, and thus over 500 t of sulfuric acid can be saved per year in chlorine treatment process of 100 kt/a caustic soda devices.
