Abstract:
1. An industrial process, for the separation of a compound from a fluid mixture, comprising the steps of: a) contacting in a container said fluid mixture with at least one particle, wherein the at least one particle contains a gas and has a density, whereupon said compound is bound to said particle; b) changing the pressure of said fluid mixture, whereby, as a result of changing said pressure, the gas contained in the particles is compressed or decompressed and the density of the particle changes more than that of the fluid mixture, resulting in downward or upward movement of said particle in said fluid mixture; and c) separating said particle from said fluid mixture, wherein said particle comprises a compressible balloon-like gas-filled core made of polymeric material and a porous shell.
