Abstract

Fouling reduces the thermal efficiency of heat transfer units, and it causes economic losses and has a marked effect on CO₂ releases and thus on climate change. In order to improve the energy efficiency, deposition formation (precipitation and crystallization) onto the heat transfer surfaces is going to be mitigated. A way to achieve this goal is the development of new surface materials with controlled chemical composition and morphology. In this study, formation mechanism of CaCO₃ depositions was investigated on modified (-CH₃ and -COOH) organo silicon (SiOC), and anatase and rutile TiO₂ surfaces. The results were compared to those of stainless steel surfaces. Based on the molecular modelling results, anatase and -COOH functionalized SiOC coatings are promising materials for mitigation of fouling caused by CaCO₃.
