A scum supply pipe containing impure gas is connected to the container filled with nitrogen, and most of the impure scum is removed.
A liquefied impurity gas remover that connects a heat exchanger tube to be liquefied and separates and removes liquefied impurity gas (hereinafter referred to as liquefied impure gas), for example, a liquid chamber separator and a plurality of liquefied impurity gas removers around the liquid chamber separator. A low-temperature vacuum vessel is commonly used in which activated carbon, which has a cylindrical shape and which adsorbs and removes impurity gas that has not been liquefied in the heat transfer tube, is immersed in liquid nitrogen and held inside.

低減するものである。The present invention provides a vacuum insulated container filled with a refrigerant, a heat transfer tube connected to a gas supply pipe, a liquefied impurity scum remover connected to the heat transfer tube, and activated carbon in the refrigerant. In the low-temperature refiner 9J installed in the immersed state, the activated carbon has a tubular shape, and the activated carbon is arranged in at least one layer concentrically with the liquefied impurity scum remover, and the activated carbon is filled into a container. By reducing the amount of refrigerant used, the time required to regenerate activated carbon is shortened, and running costs are also reduced.

。The scum containing impure gas is supplied to the heat exchanger tube 13 via the scum supply pipe 12, and while flowing through the heat exchanger tube 13, the liquid nitrogen filled in the container 11 is cooled to a temperature of Most of it is liquefied. This liquefied impure gas is supplied to the liquid chamber separator 14 together with the scum and impurity scum that has not been liquefied in the heat transfer tube 13, where the liquefied impurity scum is separated and removed. Moreover, the impure scum that has not been liquefied is adsorbed and removed by the activated carbons 15 a to 15 c while passing through the activated carbons +5 a to 15 c together with the scum. Note that the purified gas from which impurity residues have been removed is then taken out of the container II and separately sent to a user (not shown).

を減量できる。In the low-temperature purifier like this example, three layers of tubular activated carbon are arranged concentrically with the liquid chamber separator and installed inside the i1 container, so the amount of liquid nitrogen filled in the container can be reduced. Therefore, in order of the release time of liquid nitrogen from the container before the activated carbon is regenerated, the time for filling the container with liquid nitrogen after the activated carbon is regenerated can be shortened, and the consumption percentage of the liquid nitrogen can be reduced. M
can be reduced.
