In decreasing the carbon footprint of process industry, the controlling of energy efficiency of process equipment has a significant role. One of the most marked factors in improving the energy efficiency is the mitigation of precipitation and crystallization onto the heat transfer surfaces. In many cases, analysis of deposited materials reveals that the trace compounds of process fluids are concentrated onto surfaces. Thus, trace compounds can affect fouling rate, structure and morphology of deposited materials and adhesion strength of depositions on the surfaces. In this study, formation of CaCO3 depositions in the presence of magnesium ions was investigated on stainless steel, diamond and zirconium nitride surfaces. The aim of the study was to clarify the effect of magnesium on the crystallization fouling. This work consisted of both molecular modelling research and experimental fouling experiments at the laboratory scale in order to clarify the detailed mechanisms for the deposition formation.
