氢的转化利用情况对于化石燃料多联产系统的能量集成特性影响十分重要.通过关联氢与多联产系统目的化学品的转化速率以及过程的(?)变,本文提出了一种新的用于氢工艺过程能量分析和集成的图式分析方法—流量(?)变图FED(Flowrate-Exergy Diagram).该方法可以直观、简明地描述复杂系统中氢或含氢化学品量改变所引起的热力学代价。本文介绍了FED的特点,提出了使用FED的启示性准则,并将该方法应用于天然气基乙炔多联产集成系统,新系统的内部(?)损失比传统分产工艺减少了16.2%,H2消耗量减少了15.7%.

The influence of conversion and utilization of hydrogen on the characteristics of energy integration in fossil fuel poly-generation systems is very important. This paper presents the flowrateexergy diagram （FED）, a novel graphic method for energy analysis and integration in hydrogen processes. This method can visually and concisely describe the thermodynamic payment caused by the flowrate change of hydrogen and chemicals. This paper introduces the features of the FED, proposes a series of revelatory criteria for using the FED, and applies this method to a poly-generation system of acetylene process based on natural gas. The exergy loss and hydrogen consumption of the novel system are lessened 16.2% and 15.7% than the traditional processes respectively.
