摘要： A raw gas containing a gas component A with low affinity with an adsorbent and a gas component C with high affinity with the adsorbent are sequentially supplied to at least three adsorption columns, while a desorption gas containing a gas component D which differs from the gas components A and C is supplied to each of the adsorption columns other than the one to which the raw gas is being supplied. When the raw gas is supplied to the adsorption columns, the gas component A having lower affinity with the adsorbent exits the adsorption columns earlier than the gas component C having higher affinity. The gas components A and C can thus be separated from each other. When a gas including an enriched gas component A is discharged from the outlet of each adsorption column, the full amount is extracted out of the system. When a gas including an enriched gas component C is discharged from the outlet of each adsorption column, the full amount is extracted out of the system. When the gas mixture containing the gas components A and C is discharged from the exit of each adsorption column, all the discharged gas is fed back to the inlet of the adsorption column to which the raw gas is being supplied. It is possible to efficiently and sequentially separate the gas components A and C with this simple structure.

摘要： An apparatus and a method for separating a specified gas from a gas to be treated containing the specified gas comprising at least one ingredient, which comprises allowing the gas to be treated to flow through a column without the use of another gas for transferring the gas to be treated, while keeping the inside of the column packed with a packing material at a reduced pressure. The above apparatus and method can be suitably used for separating a specified gas having a high purity at a low cost.

摘要： A discharge gas containing PFC gas including CF4 and NF3 generated from a manufacturing process (10) is adsorbed at an adsorbing device (18) and then desorbed using nitrogen as a purge gas. A desorbed gas with CF4 and NF3 concentrated can be obtained in this manner. The desorbed gas is then supplied to a chromatographic separator (20) for chromatographic separation with nitrogen as a carrier gas. In this manner, CF4 and NF3 within the PFC gas can be separated. In particular, because the gas is once concentrated at the adsorbing device (18), chromatographic separation of the gas constituents can be efficiently performed. By independently concentrating CF4 and NF3 obtained by the chromatographic separation, high purity gas constituents of the PFC gas can be obtained, and reused at the manufacturing process (10).
