Abstract:
A method of removing ammonia from a continuous vent gas stream of a urea plant, in particular of a medium-pressure section of a urea plant, includes a step of removing ammonia from the continuous vent gas stream of the urea plant using a controlled-combustion process including at least a first lean, oxygen-poor combustion step performed in the presence of an understoichiometric amount of oxygen acting as the sole comburent, and in a reducing atmosphere of hydrogen.
