Abstract:
     The invention relates to a method of recovering nutrients from the flue gases of a fertilizer plant by exposing hot, almost water-saturated reaction gases obtained from the fertilizer production process to a countercurrent scrubbing and by scrubbing the hot gases obtained from the drying of the fertilizer, is order to recover the gaseous impurities present in the gases. According to the invention, the hot gases obtained from the drying of the fertilizer are scrubbed with the scrubbing solution coming from the countercurrent scrubbing of the hot, almost water-saturated reaction gases, in order to concentrate this scrubbing solution before it is returned to the fertilizer production process.
