Title: The Innovations of Gérard Hotier

Introduction

Gérard Hotier is a prominent inventor based in Rueil Malmaison, France. He has made significant contributions to the field of chemical engineering, particularly in the area of hydrocarbon processing. With a total of 12 patents to his name, Hotier's work has had a substantial impact on the industry.

Latest Patents

One of Gérard Hotier's latest patents is a coproduction process for para-xylene and ortho-xylene, which involves two separation steps. This innovative process utilizes a simulated counter-current fluidized bed system in a chromatographic column containing at least five zones. The process begins with the injection of a batch of hydrocarbons and a desorption agent, resulting in the delivery of an extract, a refined product, and an intermediate refined product. The refined product, which is richer in ortho-xylene than the intermediate refined product, undergoes distillation to extract the desorption agent. This agent is then injected into the simulated counter-current fluidized bed system, which continuously delivers an extract and a refined product.

Another notable patent is a device for injecting a diverted fluid into a simulated moving bed separation process. This invention further showcases Hotier's expertise in enhancing separation processes within chemical engineering.
