Abstract: The disclosure pertains to a fluidized bed granulation process, for instance for urea melt. An embodiment of the process comprises providing a fluidized bed of the particles in a granulation compartment of the fluidized bed granulator; forming a film of the granulation liquid in the form of a hollow conical frustum projecting into the granulation compartment by supplying the granulation liquid through a first channel of a granulation nozzle; supplying secondary gas stream through a secondary gas channel of the granulation nozzle into the granulation compartment, wherein the secondary gas channel is provided as an annulus around the first channel, wherein the exit of the secondary gas channel is directly exposed to the fluidized bed in the granulation compartment, wherein particles from the fluidized bed are entrained in said secondary gas stream.

Abstract: Disclosed is a method for the production of urea allowing a substantial reduction, even down to zero, of the continuous emission of ammonia conventionally resulting from such a process. According to a preferred embodiment of the invention, the urea-forming reaction from carbon dioxide and ammonia is conducted in a synthesis section that does not require passivation by oxygen. As a result of the absence of oxygen, a hydrogen-rich gas stream results from the synthesis section, that can be used as a fuel in an incinerator. In the incinerator, ammonia-comprising gas streams from the urea production process are combusted.

Abstract: The present invention relates to a plant for performing a method for hydrogen production or for performing a method of hydrogen and/or carbon dioxide production from syngas. The method comprises the steps of: (i) providing a gas stream comprising hydrogen and carbon monoxide, (ii) separating at least part of hydrogen from the stream yielding a hydrogen-depleted stream, (iii) subjecting the hydrogen-depleted stream to a water-gas shift reaction, and (iv) separating hydrogen from the stream resulting from step (iii).
