Title: François Loviat: Innovator in Devolatilisation Technology

Introduction

François Loviat is a notable inventor based in Sennhof, Switzerland. He has made significant contributions to the field of devolatilisation technology, holding a total of 5 patents. His work focuses on innovative methods and apparatuses for processing viscous liquids and vapor mixtures.

Latest Patents

One of his latest patents is a devolatilisation apparatus and a process for its use. This static devolatilisation apparatus is designed for devolatilising a viscous liquid that contains a volatile component. The apparatus features a phase separation chamber for treating the viscous liquid in a first devolatilisation step, resulting in a first devolatilised viscous liquid. Additionally, it includes a distributor sub-unit located below the phase separation chamber, which facilitates a second devolatilisation step. This invention is particularly useful in the devolatilisation of polymer melts or solutions.

Another significant patent by Loviat is a method for removing an ester from a vapor mixture. This method involves contacting the vapor mixture with an aqueous solution containing the corresponding acid. The process includes several steps, such as heating, reaction, and cooling, which effectively reduce the ester content in the aqueous solution. The apparatus designed for this method is also applicable in the production of lactide or polylactic acid polymers.
