During the past decade, the potential application of nuclear magnetic resonance (CNMR) imaging techniques to industrial processing problems has been recognized. The particular strength of NMR is its ability to distinguish between chemical species and to yield information simultaneously on the structure, concentration distribution and now processes occurring within a given process unit. In this paper, examples of specific applications are discussed including the study of (i) ceramics processing, (ii) the structure of polymeric materials and the application of polymers in controlled release technology, (iii) transport in porous media, (iv) transport in reactors, (v) food processing, and (vi) two-phase flow.
