Abstract
A device for extraction of pollutants by multichannel tubular membrane containing at least one fluid channel allowing the fluid to go through a feed inlet to an outlet end characterized in that membrane comprises at least an extraction channel filled with molten salt in order to adsorb said pollutants having to be extracted from the said fluid. Advantageously, the membrane is a ceramic membrane. An application is for the treatment of traces of pollutants in a liquid or gaseous fluid. For example, the removal of small pollutants as volatile organic compounds from an aqueous stream in industrial wastewater treatment or other water treatment applications, or the separation of aromatic compounds form an hydrocarbon feed in petrochemical applications. Another application is in the removal of water traces in products of high added value as pharmaceutical, cosmetic or biocarburant for example.
