Title: Nicolas Chantant: Innovator in Cryogenic Distillation

Introduction

Nicolas Chantant is a notable inventor based in Grenoble, France. He has made significant contributions to the field of cryogenic distillation, holding a total of 4 patents. His innovative methods have advanced the separation of gases, particularly in the production of biomethane.

Latest Patents

One of Chantant's latest patents is a method for separating a mixture containing at least nitrogen and methane. This process utilizes cryogenic distillation in two columns operating at different pressures. The first column separates the mixture to create a gas enriched in nitrogen and a liquid enriched in methane. The nitrogen gas is then partially condensed in a heat exchanger and returned to the first column for further processing.

Another significant patent involves a method for distilling a gas stream containing oxygen. This process is designed for producing biomethane by scrubbing a biogas feed stream. The feed gas is introduced into a pretreatment unit, where a CO-depleted gas stream is partially separated from CO and oxygen. This stream is then subjected to cryogenic separation in a distillation column, resulting in a CH-enriched stream.

Career Highlights

Chantant has worked with prominent companies in the field, including Air Liquide Société Anonyme Pour L'étude Et L'exploitation Des Procédés Georges Claude. His experience in these organizations has allowed him to refine his expertise in gas separation technologies.

Collaborations
