【摘要】：空分装置指的是将空气中的各组份气体分离,生产出氧气、氮气、氩气等气体的一套系统化工业设备。空分装置广泛应用于石油、化工、冶金、钢铁等各行业的工业生产活动中,在各行业生产中起着非常重要的作用。由于大庆石化120万吨/年乙烯工程对氮气的需求量增加,需要增加氮气的生产和供应。根据氮气供需状况,决定对大庆石化6000空分装置进行技术改造,扩能达到6000 Nm3/h氧气、20000 Nm3/h氮气的生产能力。本文首先介绍了国内外空分行业的技术及发展情况,然后对6000空分装置改造前的总体情况如装置概况、工艺原理、工艺流程、物料平衡、产品规格、公用工程消耗及能耗指标情况进行了介绍。并对装置的设计及实施情况进行介绍、分析:介绍了装置进行改造的必要性、总体方案的确定、方案的详细设计、项目设计工作计划以及进度要求;分析了项目施工总体安排、施工组织存在的难点和重点、重要的施工技术方案。最后从功能、技术、能耗等方面对项目实施后的效果进行评价研究,并得出结论:装置实际性能达到设计性能指标要求,装置的保外供能力明显增强,装置设备技术及流程技术具有先进性,装置能耗显著降低。
[Abstract]:The air separation unit refers to a set of systematic industrial equipments which separate the air components and produce oxygen, nitrogen, argon and other gases. Air separation units are widely used in the industrial activities of petroleum, chemical, metallurgical, steel and other industries, and play a very important role in the production of various industries. The production and supply of nitrogen should be increased because of the increasing demand for nitrogen gas in 1.2 million t / a ethylene project of Daqing Petrochemical Company. According to the situation of nitrogen supply and demand, it is decided to carry on the technical transformation to the 6000 air separation unit of Daqing Petrochemical Co., Ltd., and to expand the production capacity of 6000 Nm3/h oxygen and 20000 Nm3/h nitrogen gas. This paper first introduces the technology and development of the air separation industry at home and abroad, and then introduces the general situation of the 6000 air separation unit before revamping, such as the general situation of the unit, the principle of the process, the technological process, the material balance, the product specifications, etc. The consumption and energy consumption index of public works are introduced. And the design and implementation of the device were introduced, analysis: introduced the necessity of the transformation of the device, the determination of the overall scheme, the detailed design of the scheme, the project design work plan and schedule requirements; This paper analyzes the overall arrangement of the project, the difficulties and emphases of the construction organization, and the important construction technical scheme. Finally, from the aspects of function, technology, energy consumption and so on, the effect of the project is evaluated, and the conclusion is drawn: the actual performance of the device meets the requirements of the design performance index, and the outsourced supply capacity of the device is obviously enhanced. The equipment technology and process technology are advanced, and the energy consumption of the plant is significantly reduced.
