PURPOSE:To easily and separately obtain fluids with different adsorptive force from a mixture consisting of at least three kinds of components by reciprocally carrying out circulating and moving process without carrying out the process to introduce the fluids into and take them out of filled beds and carrying out supplying and taking out process of the raw material fluid and/or desorbed fluid. CONSTITUTION:A large number of beds whose insides are filled with a separating agent are connected one another in series. A raw material supplying process involves the following: under the condition that a fluid in the insides of the filled beds U is stopped circulating, a raw material fluid is supplied to a previously determined bed and the fluid is moved to another bed from the former bed and a fluid which is rich in a component with middle level adsorptive force is taken out of the latter bed. Then, without being supplied to or taken out of the filled beds U, the fluid is moved and circulated. Further, under the condition that the circulation us stopped, a desorptive fluid is supplied to any bed, moved to another bed from the former bed and thus a fluid which is rich in a component with weak adsorptive force is taken out of the latter bed and a fluid which is rich in a component with strong adsorptive force is taken out between them. Further, without being supplied to or taken out of the filled beds, the fluid is circulated. |
