摘要
针对某炼油装置凝结水现场直排、水质较差的现象,通过对凝结水管网进行优化和改进,实现了整个装置凝结水集中回收,避免了凝结水直接排放,减少催化锅炉除盐水用量,节约了用水量和运行费用;采用除油除铁设施,提高了锅炉给水品质,降低了锅炉排污率;以热水为媒介回收凝结水的热量作为气分装置的加热热能,降低了蒸汽消耗,实现了凝结水热能回收利用,凝结水水质的提高也为锅炉及其它用汽设备的长周期、稳定运行提供了保障。
In order to solve the problem of poor quality of condensate water discharged directly from the refining unit,the condensate water network has been optimized for centralized recovery to avoid direct discharge,raise water quality,reuse condensate heat,reduce water consumption and cut operating cost.The improved condensate water quality can also help ensure the long-term and stable operation for boilers and other steam-using equipment.
