Mass transfer

As a mass transfer or mass transfer, diffusion processes are referred to a boundary time. The interface may be a phase boundary or membrane ( Membrane ).

In general, the mass transfer to or from a fluid flow takes place, it is also called convective exchange. The flow is driven by gravity, the mass transfer is dependent on the driving gap, but in any case. Of the diffusion paths, the phase boundary surface, and the contact or residence time

Mass transfer equipment, such as columns, try the mass transfer area by internals while reducing the diffusion distances increase. Only in this way even small driving gradient can be used or short residence times can be realized.

If technical equipment is reduced, then always the surface to volume ratio is improved. Mass and heat to facilitate transitions. Consequently, therefore, the aim of the technical development onto microstructured materials and micro-reaction technology.
