炼化行业一体化炼油装置的高速发展，特别对炼化行业老装置能耗带来巨大的挑战，通过装置能耗分析研究，生产工艺优化创新，大胆提出给解吸塔中段增加中间再沸器后，使装置能耗与水自然资源充分利用与改善，使中间产品生产成本有效控制并降低，从而延长设备使用寿命，节约水资源，装置能耗由 64.16kgEot/t 降低到47.52kgEot/t，实现节能增效并为企业带来一定经济和社会效益。“,”the rapid development of integrated refining units in the refining and chemical industry has brought great challenges to the energy consumption of the old units in the refining and chemical industry. Through the analysis and research of the energy consumption of the unit, the optimization and innovation of the production process, it is boldly proposed that after adding an intermediate reboiler to the middle section of the desorber, the energy consumption and natural water resources of the unit can be fully utilized and improved, and the production cost of the intermediate products can be effectively controlled and reduced, So as to extend the service life of the equipment, save water resources, reduce the energy consumption of the device from 64.16kgeot/t to 47.52kgeot/t, realize energy saving and efficiency, and bring certain economic and social benefits for the enterprise.
