废碱氧化系统开车以来出现的问题及采取的措施

PROBLEMS IN SPENT CAUSTIC OXIDATION SYSTEM SINCE START-UP AND THE CORRESPONDING MEASURES

作为乙烯装置重要的环保处理单元,废碱氧化系统在装置清洁生产过程中至关重要。中沙(天津)石化有限公司乙烯装置经过10个月的摸索,废碱氧化系统运行与维护水平不断提高,出口废水排放指标COD逐步降低,保证了装置的绿色生产和节能减排。

Spent caustic oxidation system is very important for the environmental protection of ethylene plant and is very essential for cleaner production.After 10 months of efforts,Saudi Arabia(Tianjin) Petrochemical Co.,Ltd.continuously improved the operation and maintenance level of spent caustic oxidation system in ethylene plant and gradually reduced the COD in wastewater discharge,thus ensuring environment protection as well as energy saving and emission reduction.
