  • Apparatus and method for treatment of process vapours coming from a vacuum concentration section of a urea plant
    Patent number: 11376542
    Abstract: An apparatus for treatment of process vapours coming from a vacuum concentration section of a urea plant, comprising a vacuum system having a plurality of successive condensation stages, connected in series by respective line portions and crossed in series by process vapours to be treated; the apparatus has at least one primary steam condensate inlet for feeding steam condensate to the vacuum system and positioned, with reference to a circulation direction of the process vapours in the vacuum system, upstream of at least one selected condensation stage, or in at least one selected condensation stage.

  • System and a method for analysis of vent gas of a urea plant
    Patent number: 11243168
    Abstract: A system for analysis of vent gas of a urea plant, comprising: a Raman spectroscope; a sampling conduit that connects the spectroscope to a main pipe of the urea plant configured to convey a sample stream to be analysed to the spectroscope; and a temperature-adjusting device, operated by a temperature controller and acting on at least one thermal treatment portion of the conduit configured to adjust the temperature of the sample stream circulating in the conduit.
