dc.description.abstract

Calcium sulphate scaling is a serious problem encountered in many industrial and domestic applications. Supersaturation has been proven to be the major driving force of scale formation, but the solubility of calcium sulphate changes with temperature. The main purpose of this work is toinvestigate the effects of temperature on the formation of calcium sulphate scales in pipes, using a pipe flow system. Various levels of supersaturation of the calcium sulphate solution have been employed at different temperatures. Results indicated that higher temperature produced a large increase of scale amounts and a significant decrease of induction periods. Many forms of hydrated calcium sulphate were created at high temperature. The relationship between deposited scale mass and temperature was deduced from experimental data. From the relationship between induction period and temperature activation energies of the surface nucleation were estimated to be in the range of 42 to 48 kJ mol-1.
