Abstract (en)
[origin: WO2020234055A1] Method for adjusting a gas stream separation unit comprising N adsorbers, where N ≥ 2, each following a PSA, VSA or VPSA adsorption cycle, with an offset of a phase time, said adjustment method comprising the following steps: a) for at least one step of the adsorption cycle, continuously measuring a physical parameter associated with the gas stream entering and/or leaving the adsorber; b) determining at least one characteristic value of the step chosen in step a) which is chosen from the values of the physical parameter measured in step a) or a function of those values; c) comparing this characteristic value with a target value; and d) in the event of a variation between the value of this or these difference(s) and the target values, modifying the flow of the gas stream in order to obtain the target value, where steps a) to d) are performed for each adsorber, and where at least one adsorber has a target value different from the target values of the other adsorbers
