Abstract


The formation of scales in pipes and on the surfaces of vessels is one of the major problems encountered by the mineral processing industry in Australia and elsewhere. A cursory study revealed that one of the main components of the scales was gypsum or calcium sulfate dihydrate. This paper discusses a typical undergraduate laboratory project to investigate the formation of calcium sulfate dihydrate scale on the surfaces of different types of pipes under isothermal conditions. This laboratory exercise is essentially a crystallization process and is suggested as one of the topics for final-year chemical engineering undergraduate project since it is a very important unit operation in the chemical, mineral, or pharmaceutical industries. Keywords: Calcium sulfate dihydrate, laboratory project, scale formation, and undergraduate curriculum..
