Scaling of calcium carbonate (CaCO3) in pipes: Effect of …
Calcium carbonate scale usually precipitates and grows on industrial equipment such as piping system, causing blockages in the pipes, thus reducing mass and heat transfer. This paper presents experimental results of calcium carbonate scale formation in a piping system. The scale-forming solution was prepared by mixing equimolar solutions of CaCl2
