摘要
介绍了中国石化集团金陵石化有限公司200 t/h污水汽提装置工艺流程及存在问题。72 h标定期间,该装置运行稳定,原料与产品物料基本平衡,产品收率为96.96%,主要操作参数与设计值相当,装置总能耗为17.295 kg EO/t,原料及产品质量全部合格。针对装置能耗偏高和氨精馏系统设备腐蚀等问题,提出针对性改进措施和建议。装置技术改进后能耗指标将大幅度降低,设备腐蚀可进一步缓解,为装置稳定高效运行打下基础。
The process flow and existing problems of 200 t/h sewage stripping unit of SINOPEC Jinling Petrochemical Co.,Ltd.are introduced.During the 72 h calibration period,the unit operates stably,the raw materials and product materials are basically balanced,the product yield is 96.96%,the main operating parameters are equivalent to the design value,the total energy consumption of the unit is 17.295 kg EO/t,and the quality of raw materials and products are all qualified.Aiming at the problems of high energy consumption and equipment corrosion of ammonia distillation system,targeted improvement measures and suggestions are put forward.After the technical improvement of the unit,the energy consumption index will be greatly reduced,and the equipment corrosion can be further alleviated,laying a foundation for the stable and efficient operation of the unit.
