ABSTRACT
In mass transfer operations between different points of a system, transport of the components takes place by means of molecular or convection mechanisms, which implies a displacement of the molecules of the components from the points with higher concentration to those of lower concentration. Globally, the transfer is carried out by concentration gradients; thus, when concentration equilibrium is reached, the mass transfer stops. For this reason, in order to improve transfer performance, it is important to work far from the equilibrium conditions.
