Abstract

See full text

A gas diffusion system configured to feed a gas stream, in particular a passivating gas stream, into an apparatus, in particular a decomposer, of a urea plant; the system extends along an axis and has a gas feed conduit having an outlet from which the gas flows substantially parallel to the axis, and a diffuser assembly configured to diffuse the gas supply from the conduit; the diffuser assembly is shaped so as to intercept the gas stream flowing axially from the outlet, and divert the gas stream substantially radially with respect to the axis and uniformly about the axis.
