Abstract: An arrangement comprising at least one liquefaction plant for liquefying a gaseous medium to produce a liquefied medium; and at least one storage tank for storing the liquefied medium. At least one first transfer line is connected between the liquefaction plant and the storage tank, for transferring liquefied medium from the liquefaction plant into the storage tank. At least one second transfer line is connected between the liquefaction plant and the storage tank, for transferring gaseous medium from the storage tank into the liquefaction plant. At least one shut-off valve is provided in each transfer line. The apparatus further includes a bypass line.

Abstract: Method for operating an adsorber arrangement comprising a first and a second adsorber device, arranged in parallel between an upstream process device providing a process gas and a downstream process device receiving a purified process gas. The method comprising during a process of purifying the process gas with the first adsorber device, cooling the second adsorber device by passing a portion of purified process gas, received from the first adsorber device, through the second adsorber device; and directing the process gas portion that has passed through the second adsorber device to the upstream process device. Then, the first and the second adsorber devices are sequentially coupled, such that process gas from the upstream process device passes through the second adsorber device for cooling the second adsorber device, and then through the first adsorber device. Finally, purified process gas is received at the downstream process device from the first adsorber device.
