Title: The Innovative Contributions of Pierre Bergez
Introduction
Pierre Bergez is a notable inventor based in Paris, France. He has made significant contributions to the field of filtration technology, holding a total of 7 patents. His work focuses on ultrafiltration, hyperfiltration, and demineralization processes, which have applications in various industries.
Latest Patents
One of Bergez's latest patents is an ultrafiltration, hyperfiltration, or demineralization element. This element comprises a porous inorganic material support and an asymmetrical, cellular, microporous organic polymer membrane. The membrane is produced on one of the faces of the porous support and is fitted into the pores of the porous support flush with the surface. The preparation involves coating the inner surface of a tubular porous support with a coating solution of the organic polymer, followed by a polymer insolubilization stage. Another significant patent is a process for deasphalting a hydrocarbon oil. This process employs a hydrocarbon solvent of 3-8 carbon atoms, resulting in an asphaltic phase and a solution of deasphalted oil in the solvent. The solvent is then separated from the deasphalted oil by passing the solution tangentially across an inorganic membrane, which selectively retains the deasphalted oil.
