Abstract
Several impure gaseous streams, e.g., hydrogen-containing streams from a hydrogenation system, under different pressures and consisting essentially of the same components, are purified by multistage fractional condensation. The condensates separated from the gaseous streams at higher pressures are expanded to the lower pressure of another gaseous stream and introduced into the latter.
