    • The invention relates to a method of purifying air, a process for manufacture of fertilizer and an apparatus for purifying air by scrubbing with an acid. The apparatus for purifying air contains washing liquid and comprises: at least one air cleaning unit comprising a scrubber in which the air to be purified is washed with the acid containing washing liquid, and from which the purified air and the spent washing liquid is withdrawn; and a washing liquid control unit, arranged in a distance from the air cleaning unit(s), in which the composition of the spent washing liquid withdrawn from the scrubber is readjusted, if desired, by addition of fresh water and fresh acid and withdrawal of a corresponding amount of the spent washing liquid as a product, such as a fertilizer mixture, before the optionally readjusted washing liquid is transferred to and introduced into the scrubber as acid containing washing liquid. Furthermore the invention relates to a building provided with an apparatus for purifying air.
