Abstract:
Method of controlling a plant for processing a gas by adsorption, which plant (10) has N adsorption units (R1 to R0), N being greater than or equal to two, operating according to a cycle which is distributed uniformly into at most N phase times and during a part of which at least one of the adsorption units is subjected to the output flow of at least one of the other adsorption units, in which at least one control sequencer is used which determines the control steps of the N adsorption units (R1 to R0) over a cycle and which ensures, in a loop on itself, cyclic operation of the processing plant (10), and in which, on the basis of the control steps of the processing plant (10) which occur during a given phase time of a cycle of an operating mode of the plant, said sequencer of said operating mode is obtained by extrapolation to the other phase times of the cycle.
