of two technical options for the oxygen supply of a hospital. The systematic comparison of the alternative&#13;
processes using the PhO as a benchmark for the minimum input (exergy in this case) required&#13;
to run a process with a certain benefit allows to determine the potential for optimization of&#13;
each technology. Differences are analyzed by visualizing the losses of each individual production&#13;
step in a process as well as by the resulting overall energy demand, including the primary energy.&#13;
Possible alternatives are purchasing liquid oxygen from a cryogenic process or the production by&#13;
means of Pressure Swing Adsorption (PSA) on site. The cryogenic production shows a lower exergy&#13;
demand even though it also has a higher potential for optimization. Yet, the total losses, significantly&#13;
impacted by the unavoidable transportation, sum up, resulting in the conclusion that the PSA is the&#13;
preferable option overall, considering energy aspects. Finally, additional criteria such as economic,&#13;
legal, and structural consequences of the respective choices are briefly outlined.</style></abstract><publisher><style face="normal" font="default" size="100%">MDPI</style></publisher><pub-location><style face="normal" font="default" size="100%">online</style></pub-location><issue><style face="normal" font="default" size="100%">5</style></issue></record></records></xml>
