Abstract:

Under the background of the national implementation of the dual carbon strategy and dual control of energy consumption, combined with the design of the ADU&VDU of a domestic refinery, the study was carried out on how to further reduce the energy consumption and carbon emissions of the unit. With the three optimized technical schemes of “deep heat combined technology”“flash evaporation of prefractionator residue” and “flash evaporation of AR”, it is concluded that the energy consumption of the unit can be reduced by 0.54 kgoe/t, 0.61 kgoe/t and 0.54 kgoe/t respectively, corresponding to the reduction of CO₂ emissions by 18,000 TPY, 20,300 TPY and 18,000 TPY respectively. The feasibility of this method is also briefly analyzed.

摘要：

在国家实行能耗双控和双碳战略的背景下，结合国内某炼油厂常减压蒸馏装置的设计，就如何进一步降低装置的能耗和碳排放进行研究，针对“深度热联合技术”“初底油闪蒸”和“常底油闪蒸”3个优化技术，对比分析，得出可以分别降低装置能耗0.54,0.61,0.54 kgoe/t,对应分别减少CO₂排放18.0,20.3,18.0 kt/a,对可实施性进行了简要分析。
