ABSTRACT:
A method and systems for separating fluids of differing masses from a mixture by enhanced diffusion wherein the method and systems embody at least one cycle wherein the mixture of fluids of differing masses is fed into a first reservoir which is connected by at least one duct to a second reservoir; a carrier fluid is fed into a second reservoir; oscillatory axial movement of fluid within the at least one duct is established; a mixture of carrier fluid and a mixture of fluids of differing masses enriched in the component thereof having higher effective diffusion coefficient is withdrawn from the second reservoir; a mixture of carrier fluid and a mixture of fluids of differing masses enriched in the component thereof having the lower effective diffusion coefficient is withdrawn from the first reservoir; such that a positive flow of the carrier fluid is maintained from the second reservoir through the at least one duct into the first reservoir.
