Title: Chantal Rigaill: Innovator in Natural Gas Purification

Introduction

Chantal Rigaill is a notable inventor based in Yerres, France, recognized for her contributions to the field of natural gas purification. With a total of three patents to her name, she has developed innovative methods that enhance the efficiency and effectiveness of gas treatment processes.

Latest Patents

One of her latest patents is a method of purifying natural gas by mercaptan adsorption. This process involves deacidizing and dehydrating raw natural gas in designated units. The treated gas is then purified through the adsorption of mercaptans in a first enclosure. A portion of the purified gas is heated and fed into a second enclosure to discharge water adsorbed by the adsorbent material. The water-laden purge gas is subsequently processed in a third enclosure, where mercaptans are desorbed and replaced by water. The gas from this enclosure is then washed and recycled, showcasing an efficient cycle of purification.

Another significant patent by Rigaill is a method of regenerating an aqueous glycol solution containing salts. This method involves expanding the glycol solution in a drum and distilling it in a column. The concentrated glycol is placed under vacuum to vaporize water and precipitate salts, which are then separated from the glycol. The resulting concentrated glycol, now free of salts, is stored for further use.
