Abstract

For hydrogen network, the Fresh Hydrogen Purity (FHP) and the purification affect its Hydrogen Utility (or fresh hydrogen) Consumption (HUC), and should be optimized simultaneously. Based on the quantitative relation among Hydrogen Utility Consumption (HUC), FHP and purification, a graphical method is developed to integrate the hydrogen network with the FHP and Purification Feed flow rate (PFFR) optimized simultaneously. Firstly, at given HUC, the relationship between PFFR and FHP is derived for sink-tie-lines with different locations. Then, the FHP versus PFFR diagram is plotted to analyse their relation. With the cost of fresh hydrogen and purification considered, the total cost (including the cost of fresh hydrogen and purification) versus FHP line is constructed to identify the optimal PFFR and FHP. The hydrogen network of a petrochemical enterprise is optimized by the proposed method with the optimal purification feed and fresh hydrogen purity identified.
