摘要
针对陕西延长石油集团榆林炼油厂疏水系统和凝结水回收系统等方面存在的蒸汽泄漏严重、冷凝水回收少、水质差难以达到锅炉等用水要求的问题。采用背压回水与加压回水相结合的蒸汽管网节能技术,将所有凝结水回收并精处理,处理后的凝结水送至蒸汽动力装置进行重复使用,节约了大量蒸汽,改善了低温余热的平衡状态,生产装置运行稳定,生产成本有所降低。
Due to the imperfect steam trap system, serious leakage of steam, less recovery of condensed water happened in Yulin refinery,and the poor quality condensed water could not be used as boiler make-up water as well. By adopting energy saving technology of steam pipe network,which included a combination of back pressure return and pressurized backwater, the condensed water was fully recovered and after fine treatment, it could be used as boiler make-up water. Since then, steam and water resource were saved, the utilization of low temperature heat was improved, operations were stable and production cost was reduced in some extent
