摘　　要：采用夹点分析与炼油厂计划优化模型相结合,利用夹点分析所得出的节氢量变化曲线、氢源变化曲线与计划优化模型绘制的利润曲线,分析加氢装置氢气的最优纯度。通过以5个月为周期实例计算,分析节氢量、氢源曲线与利润曲线的关系,可确定加氢装置最优氢气质量分数为0.28,日节氢量为46.3t,利润为15 988万元。此方法在保证装置平稳运行的情况下,可优化单装置氢气质量分数,节氢量与炼油厂利润达到最优。Combination of pinch analysis and refinery plan optimization model was used to optimize the hydrogen purity for hydrogenation unit using the curves of H2 saving and the hydrogen source by pinch analysis and the profile curve from the plan optimization model.Through the calculation of operation data within 5 months,it is determined that the optimal hydrogen mass concentration for the unit is0.28,the daily saving of hydrogen consumption is 46.3 t/d and the profit is 159.88 million RMB.This method can optimize the single unit hydrogen utilization.The H2 saving and refinery profit can reach the optimal value at stable operation.
