摘  要:为了优化常减压蒸馏装置的能源利用并提高其能源利用效率,提出采用循迹法对常减压蒸馏装置进行案例研究的方法,通过分析能量设备,将装置分为5个子系统,将能量系统图与能值计算相结合,确定系统中各种输入能值的分布,分析子系统内外的能量流并计算其能量分配系数,实现系统能效瓶颈识别。将该方法应用于实际案例,将常减压蒸馏过程根据工艺特点划分为5个子系统,通过计算对比子系统中各个能量分配系数得出其能效瓶颈识别结果,证明了该方法分析复杂化学过程的有效性。For purpose of optimizing the energy utilization and improve its energy use efficiency,a method of employing the tracking method to implement the case study of the atmospheric and vacuum distillation unit was proposed.Through analyzing the energy facilities,having the unit divided into five subsystems,including having the energy diagram combined with the energy calculations,and having the distribution of various input energy in the system determined,as well as having the energy flows and energy distribution coefficients inside and outside the subsystems analyzed to realize the bottleneck detection of the system energy efficiency.Applying this method to the vacuum distillation process and having it divided into five subsystems were implemented.Through calculating and comparing each energy allocation coefficient in the subsystem,the energy efficiency bottleneck identification result was obtained,which proves the effectiveness of the method in analyzing complex chemical processes.
