Development of a versatile laboratory project for scale formation and control

Publication date: August 2012 Source:Education for Chemical Engineers, Volume 7, Issue 3 Author(s): S. Muryanto , A.P. Bayuseno , W. Sediono , W. Mangestiyono , Sutrisno Development of a laboratory rig to provide graduate students with versatile equipment for final year projects is discussed in this paper. The laboratory demonstrated scale formation and control in pipes, a persistent problem encountered in many industries. As a sample study, the laboratory has been used to investigate the influence of four parameters on the formation and prevention of calcium sulphate dihydrate (gypsum) scale. These parameters were: concentration of solutions, fluid flow rates, temperature, and presence of additives. This laboratory project has been successfully implemented in the Mechanical Engineering Graduate Program at Diponegoro University. Since the results of the sample study agree well with the literature, the present laboratory would be of importance for final year projects concerning crystallization and its practical implications in scale formation and control. Wider utilization of the laboratory, including training in scale prevention for industry, has been planned. Highlights ► A versatile laboratory rig for mechanical and chemical engineering final projects. ► The laboratory demonstrated scale formation and prevention inside pipes. ► Gypsum scale formation as a case study showed good agreement with the literature. ► The laboratory could be an important and intere...
