摘　　要：广州石化裂解装置自2003年改扩建后,工艺水系统堵塞严重。经过新增聚结器和换热器,以及甲苯萃取技术应用技改措施后,成功解决了工艺水系统堵塞问题,可以保证工艺水系统在一个大修周期(4~5 a)稳定运行,消除了因工艺水系统堵塞问题带来裂解装置停车的风险,为装置长周期运行打下了基础,节省工艺水系统在一个大修周期的维护费用60余万元。Since the modification and capacity expansion of the ethylene cracker at Sinopec Guangzhou Company in 2003,the process water system was seriously blocked.After adding new coalescers and heat exchangers and adopting toluene extraction technology,the blockage problem in process water system was successfully solved,and the stable operation of process water system throughout one overhaul cycle,i.e.4 to 5 years,can be guaranteed,thus eliminating the risk of unit shutdown due to the blockage in process water system,laying a foundation for the long-term operation of the unit,and reducing the maintenance cost of process water system in one overhaul cycle by more than 600000 yuan.
