Title: Gérard Hotier: Innovator in Paraxylene Production
Introduction
Gérard Hotier is a notable inventor based in Rueil Malmaison, France. He has made significant contributions to the field of chemical engineering, particularly in the production of paraxylene. With a total of 6 patents to his name, Hotier's work has advanced the methods used in the separation and purification of aromatic compounds.
Latest Patents
One of Hotier's latest patents is a method for producing paraxylene that involves an adsorption step and two isomerization steps. This innovative process utilizes a hydrocarbon feed and features an adsorption column operating as a simulated moving bed with at least five zones. The process efficiently delivers an extract, a 2-raffinate, and an intermediate raffinate. The extract is distilled, and the distillate can be re-crystallized to recover paraxylene with a purity of at least 99.7%. Another significant patent is for a simulated moving bed (SMB) separation device. This device includes at least one column with beds of adsorbent, trays for fluid distribution and extraction, and a multi-way rotary valve. The SMB device allows for the use of various types of distribution and extraction trays while maintaining a high level of product purity. Its applications are particularly relevant for the separation of paraxylene or metaxylene from a C8 aromatic charge.
