Abstract: A storage tank, especially for liquefied gases, is separated into cells by numerous partitions of a material having low heat conductivity. The maximum diameter of the cells in a plane that is perpendicular to the partitions is less than 50 mm.

Abstract: The disclosure relates to a process as well as an apparatus for the separation of a gaseous mixture containing essentially hydrogen, methane and carbon monoxide, wherein the gaseous mixture is subjected to a physical low-temperature scrubbing step with liquid methane, as well as to subsequent separation of H.sub.2 from the loaded methane by means of stripping and/or expansion and subsequent regeneration of the loaded methane by CO/CH.sub.4 separation. In order to minimize the losses of CO, encountered during H.sub.2 separation and/or in order to raise the yield of CO, the H.sub.2 gas obtained during the stripping and/or expansion step is brought into contact with liquid methane.
