考虑新氢纯度的氢网络夹点分析
Pinch analysis for the hydrogen network with the concentration of fresh hydrogen considered
摘要
Abstract
Based on the pinch method,the hydrogen network is integrated with the concentration of fresh hydrogen considered. Aspen Plus software is used to simulate the hydrogen production process of nature gas steam reforming producing fresh hydrogen with different concentrations. The simulation results are used to conduct the energy consumption analysis,and calculate the total cost including the raw material gas,oxygen water,cooling water,by-product of steam,pressure swing adsorption, compressor electric costs. The production cost increases as the fresh hydrogen concentration increases, and the quantitative relationship between them is determined. In the case study,the hydrogen network of a petrochemical enterprise is optimized using that relationship. Considering different hydrogen source conditions,the conserved cost versus concentration and total costversusconcentration diagrams are plotted,and the trend of hydrogen pinch is depicted. With the requirement of the hydrogen network satisfied,the conserved cost increases as the fresh hydrogen concentration increases,while the total cost decreases. It is concluded that the fresh hydrogen with high purity can benefit the energy saving in the hydrogen network design.关键词
