Abstract

Abstract: Hydrogen pinch technology is an important method of hydrogen network optimization with the advantage of simple,intuitive,efficient and easy to understand. It already has mature and stable development in resolving the hydrogen network bottlenecks since the late 1990s. This paper recommended the basic principle of the hydrogen pinch. Hydrogen pinch technology method includes hydrogen surplus graphical method,rigorous graphical targeting, pure hydrogen load versus flow rate diagram graphical method,source composite curve graphical method,deficit diagram of multiple impurities,and so on.
