Abstract
A method for producing a fertilizer that comprises urea and/or at least one ammonium compound may involve obtaining ammonia as an impurity in the production process, and photocatalytically decomposing the ammonia by irradiation with UV radiation. Further, an apparatus for producing fertilizer granules that comprise urea and/or at least one ammonium compound may include a plant section having a fertilizer granulator configured to produce the fertilizer granules, a supply line configured to pass a urea melt or a concentrated urea solution to the plant section, a UV lamp arrangement that is proximate the supply line and is configured to irradiate with UV radiation the urea melt or the concentrated urea solution flowing in the supply line.
Claims10
A method for producing a fertilizer that comprises at least one of urea or an ammonium compound, the method comprising:
- obtaining ammonia as an impurity in the production of the fertilizer;
- and
- decomposing the ammonia, as it is bound or dissolved in a urea melt or in a concentrated urea solution, photocatalytically by irradiation with UV radiation;
- wherein decomposing the ammonia photocatalytically includes irradiating the urea melt or the concentrated urea solution with UV radiation on a transport path to a fertilizer granulator.
A method for producing a fertilizer that comprises at least one of urea or an ammonium compound, the method comprising:
- obtaining ammonia as an impurity in the production of the fertilizer;
- and
- decomposing the ammonia, as it is bound or dissolved in a urea melt or in a concentrated urea solution, photocatalytically by irradiation with UV radiation;
- wherein the irradiation occurs by way of a UV lamp arrangement disposed proximate a supply line via which the urea melt or the concentrated urea solution is passed to a fertilizer granulator.
