Michel Jean FAUCONET has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Process for purifying (meth)acrylic acid including a dividing-wall distillation column
    Patent number: 10815182
    Abstract: The invention relates to the use of a column with a separating wall as a purification/finishing column in a (meth)acrylic acid recovery method based on the use of two distillation columns in the absence of external organic solvent. The method according to the invention improves the energy balance for the method while improving the technical quality of the (meth)acrylic acid recovered. The method according to the invention further produces polymer-grade (or glacial) (meth)acrylic acid compatible with the production of high-molecular weight acrylic acid polymers.
    Type: Grant
    Filed: April 3, 2018
    Date of Patent: October 27, 2020
    Assignee: Arkema France
    Inventors: Michel Jean Fauconet, Serge Tretjak

  • Process for producing (meth)acrylic acid
    Patent number: 10239816
    Abstract: The invention is directed to a process for recovering/purifying (meth)acrylic acid which does not use azeotropic solvent and is based on the use of two columns for purifying a reaction mixture comprising (meth)acrylic acid. The process according to the invention includes a dry vacuum pump condensation system, which makes it possible to reduce the amount of final aqueous discharges.
