ASPECTS OF CRYSTALLIZATION FOULING

Crystallization fouling or scale formation is temperature dependent, a nd a degree of supersaturation is required before precipitation occurs . In general, a nucleus is necessary around which crystals can form. T he mechanism of crystallization on surfaces is complex, and it is diff icult to explain in mathematical terms, although attempts have been ma de. The paper concludes with a brief review of scale formation under b ailing conditions and the deposition of wax crystals from organic liqu ids. (C) Elsevier Science, Inc., 1997.
