在保证科学合理的前提下,使用低品质介质代替质量过剩的高品质介质是一种有效的节能方式。洛阳石化110t/h污水汽提装置是酸性水处理的重要装置,利用污水汽提装置凝结水替代焦化装置多处1.0MPa蒸汽和除氧水,利用污水汽提装置净化水替代焦化装置多处新鲜水和除盐水。通过对污水汽提装置和延迟焦化装置的联合优化改造,将污水汽提装置凝结水和净化水引至延迟焦化装置使用,凝结水用于延迟焦化装置大吹汽时替代1.0MPa蒸汽、替代除氧水和装置部分伴热;净化水用于延迟焦化装置3处水封罐补水,替代2处水洗用除盐水,同时替代新鲜水补冷焦水。优化改造后,延迟焦化装置每年可节省1.0MPa蒸汽87.93Mt、除氧水32.295kt、新鲜水122.64kt、除盐水30.66kt,每年节约动力成本172.11万元。
In ensuring the scientific and reasonable premise, the use of low-quality media instead of high-quality excess media is an effective way to save energy. Luoyang Petrochemical 110t / h sewage stripping device is an important means of acidic water treatment, the use of sewage stripping device condensate instead of coking unit multiple 1.0MPa steam and oxygen water, the use of sewage stripping device to replace coking plant clean water fresh Water and demineralized water. Through the joint optimization of sewage stripping unit and delayed coking unit, the condensate and purified water of the stripping unit of the sewage stripping unit are used to delay coking unit. The condensate is used to replace the 1.0MPa steam in the large coking unit of delayed coking unit to replace deaerated water And part of the device with heat; purified water used to delayed coking unit 3 water seal tank make up water, instead of two water desalination water, while replacing fresh water make up coke water. After the optimization and reconstruction, the delayed coking unit can save 87.93Mt of 1.0MPa steam, 32.295kt of deaerated water, 122.64kt of fresh water and 30.66kt of demineralized water every year, saving the power cost of RMB 1,721,100 each year.
