Abstract: Disclosed is a method for the removal of ammonia from the off-gas of a finishing section of a urea production plant. The method comprises contacting the off-gas with a solid adsorbent capable of physically adsorbing ammonia, particularly activated carbon or zeolite. Thereupon the solid adsorbent having ammonia adsorbed thereon is separated from the gas and regenerated by dissolving ammonia in an extraction liquid, preferably water. After separating the water from the solid adsorbent, the latter is re-used in the process.

Abstract: Disclosed is a process for the concurrent production of hydrogen and sulphur from a H2S-containing gas stream, with reduced, and preferably zero, emissions. The method comprises the catalytic oxidative cracking of H2S so as to form H2 and S2. Preferably, the oxidation is conducted using oxygen-enriched air, preferably pure oxygen. The process is conducted in a reaction chamber comprising a bifunctional catalyst material, so as to favor both the partial oxidation of H2S and the dissociation thereof.

Abstract: The present invention relates to a process for the production of granules from a liquid composition with a decreased dust production, the process steps are as follows: applying the liquid composition onto solid particles that are kept in a continuous movement by a gas stream in a granulation zone of an oblong granulator, thereby depositing and solidifying liquid composition around the solid particles to increase the size of the particles and thereby form grown solid particles; discharging a stream of the grown solid particles from the granulation zone, dividing, in a size-sorting apparatus, the stream of grown solid particles into individual streams based on the size of the grown solid particles to thereby produce streams of undersized, oversized, and desired-sized grown solid particles; transferring the stream of oversized grown solid particles to a size-reducing apparatus; crushing the stream of oversized grown solid particles in the size-reducing apparatus, thereby reducing the particle size of the oversized grown solid particles and thereby producing a stream of crushed solid particles wherein that stream of crushed solid particles is introduced in the granulator at a place below the place where the gas stream leaves the granulator.
