One practical problem, if it's saturated steam, is that by increasing pressure, you're increasing the condensation point, so a lot of the steam will keep turning to liquid water without any considerable pressure growth.If you take 10l of dry air at 1 bar and compress it to 2 bar, you get about 5l of the compressed air. But if you take saturated steam - you'll get a glass of water at a little ...
