Abstract

A method (100) for operating an adsorption arrangement (10) comprising adsorption vessels (11, 12) with adsorption beds is provided. The adsorption vessels (11, 12) are operated in operating cycles including in an adsorption mode and a regeneration mode, the regeneration mode comprising a heating phase and a cooling phase subsequent to the heating phase. The method (100) comprises defining (110) one or more accumulation targets for one or more components to be adsorbed in the adsorption vessels (11, 12) in the adsorption mode, and one or more regeneration targets for the regeneration mode, determining (120), at one or more instances during the adsorption mode, a remaining adsorption time in which an adsorption vessel (11, 12) presently operated in the adsorption mode may still be operated in the adsorption mode without exceeding the one or more accumulation targets, and a total adsorption time including an elapsed adsorption time and the remaining adsorption time, and determining (130), during the remaining adsorption time, a heating time used for the heating phase, a cooling time used for the cooling phase, and one or more flow rates of one or more regeneration gases used in the regeneration mode such as to meet the one or more regeneration targets. Said determining (120, 130) the remaining adsorption time, the heating time, the cooling time, and the one or more flow rates includes using one or more tuning factors to modify at least the one or more accumulation targets and the one or more regeneration targets. An adsorption arrangement (10) as well as an air separation unit (1000) including an adsorption arrangement is also proposed.
