A nozzle arrangement in which the nozzles have a scrubber, especially for flow gas desulfurization, are laid in accordance with the following: (a) liquid concentrations of a component to be absorbed from a gas stream scrubbed in the column are measured above a plane of the nozzle assembly at N locations of a grid of equal area elements of a cross section of the column; (b) the N concentration values are compared with a predetermined value; (c) upon deviation of a measured concentration value from the predetermined value, a position of at least one of the nozzles is varied by selection of a length and location of an intermediate pipe section connecting the one of the nozzles to a respective branch pipe laterally thereon; and (d) repeating (a) through (c) until the concentration values measured above the plane are approximately equal except for at a wall region of the column.
