Hydro-processed renewable jet fuels (HRJs) have been proposed to reduce aircraft emissions. In order for HRJs to compete with petrochemical aviation fuel, it is necessary to improve their energy utilization and reduce their energy dissipation. This can reduce the energy cost for a commercial plant that hydro-processes renewable jet fuel. In this study, exergy and pinch analyses are performed to demonstrate the actual recycling heat flow and optimize heat integration. In addition, the maximum exergy destruction and energy recovery for each process unit are evaluated. The results show that the total exergy efficiency of all the products in the process is 92.24%; the energy of the obtained target product (i.e., HRJ) is 1101.40 MW, which accounts for 68% of the energy of all the products. After heat integration, the results indicated an energy saving of 208.8 MW and a utility energy efficiency of 81.97%. The exergy and pinch analyses reported in this paper can aid in improving the recyclability and energy saving capacity of the designed process.

已经提出加氢处理的可再生喷气燃料（HRJ）以减少飞机排放。为了使HRJ与石化航空燃料竞争，必须提高其能源利用率并减少其能耗。这可以降低对可再生喷气燃料进行加氢处理的商业工厂的能源成本。在这项研究中，进行了火用和收缩分析，以证明实际的循环热流和优化热集成。另外，评估了每个处理单元的最大火用破坏和能量回收。结果表明，该工艺过程中所有产品的总火用效率为92.24％。获得的目标产品（即HRJ）的能量为1101.40 MW，占所有产品能量的68％。热整合后 结果表明，节能208.8兆瓦，公用事业能源效率为81.97％。本文报道的本能和夹点分析可以帮助提高设计过程的可回收性和节能能力。
