摘要
通过试验考察了催化裂化净化水和热电中和水回用作焦化冷焦水对焦化产品质量、设备腐蚀和职业卫生安全三个方面的影响,提出了催化裂化净化水和热电中和水回用作焦化冷焦水的技术改造方案,并进行了经济效益分析。该改造方案实施后,可节约新鲜工业水240kt/a,节省水费约51万元/a;减少污水排放量240kt/a,节省污水处理费约80万元/a;同时可减少外排废水量,废水中各项污染物的排放量大大减少,环境效益显著。
The effect of using catalytic stripping sour water and neutralizing water from thermal power plant as cooling water of coke on the coke quality, equipment corrosion and production environment was investigated, and a related technical revamping scheme was proposed. Economic analysis of the proposal was discussed. It was found that after adopting said proposal, a 240 kt/a of fresh water （worth 0.51 MRMB annually）was saved and a 240 kt/a of wastewater discharge was left out,i, e. saving a wastewater treatment fee of 0.8 MRMB annually.
