  • Method for treating waste gas containing polycyclic aromatic hydrocarbons
    Patent number: 10279308
    Abstract: A process for treating effluent gas containing polycyclic aromatic hydrocarbons includes a step of spray scrubbing with a mineral oil in order to trap the hydrocarbons, wherein the mineral oil includes a mixture of aromatic mineral oil and naphthenic mineral oil.
    Type: Grant
    Filed: March 4, 2015
    Date of Patent: May 7, 2019
    Assignee: SAFRAN CERAMICS
    Inventors: Jean-François Potin, Bernard Delperier
  • CVI densification installation including a high capacity preheating zone
    Patent number: 9845534
    Abstract: A thermochemical treatment installation includes a reaction chamber, at least one gas inlet, and a gas preheater chamber situated between the gas inlet and the reaction chamber. The preheater chamber has a plurality of perforated distribution trays held spaced apart one above another. The preheater chamber also includes, between at least the facing distribution trays, a plurality of walls defining flow paths for a gas stream between said trays.

  • Method and installation for treating effluent gas containing hydrocarbons
    Patent number: 6849105
    Abstract: Prior to passing through pumping apparatus effluent gas containing hydrocarbons is subjected to washing by being sprayed with aromatic type oil in oil-recirculating washing apparatus. Polycyclic aromatic hydrocarbons contained in the effluent gas are trapped by being absorbed in the oil. The method is suitable for treating effluent gas coming from an installation for chemical vapor deposition or infiltration using a reagent gas containing a precursor for pyrolytic carbon, or else coming from a cementation installation.
