Introducing purification devices into hydrogen systems can enhance the extent of hydrogen reuse. However, the economic performance of a purification device depends on its appropriate placement within a hydrogen system. Based on some established graphical methods, this paper explores the...

Growing hydrogen demands in oil refining are forcing many refiners to optimize their hydrogen distribution networks in order to address the demands without incurring excessive energy consumption, capital investment and operating costs. In addition to the use of hydrogen utility, the foremost...

Based on the characteristics of work exchanger, a graphical integration method is developed for work exchange network. In this method, the composite curves of work sinks and work sources are plotted in the lnP versus W diagram. Two linearly approximated sink auxiliary lines are proposed to...

Based on the cumulative exergy analysis method, the effect of incorporating the Ice Thermal Storage (ITS) air conditioning system in power supply is analyzed. Not only the cumulative exergy of air conditioning system is considered, but also that of the processes consuming the power generated by...
