This study investigates the kinetics and mechanisms of CaCO3 deposition on stainless steel surfaces under flow conditions over a wide range of SR, at 25⁰C and 70⁰C. Surface induction time (tind) and CaCO3 growth are evaluated from the differential pressure build-up when scale is deposited on the walls of the capillaries in real-time.
This work aims to study the formation of calcium carbonate scale using a brine containing a calcium content close to that found in the pre-salt produced water on a carbon …
We have studied nucleation and crystal growth of calcium carbonate on hard surfaces, i.e. stainless steel and silica, at different temperatures, in relation to the corresponding bulk processes, using scanning …
Calcium Carbonate (CaCO 3) is predominantly present in cooling water which is commonly used as a coolant in many industrial processes. It has inverse solubility characteristics i.e., it is less soluble in warm water, resulting in the deposition of scale on heat transfer surfaces.
In the studied case, a stainless steel plant generating AOD slag and a paper plant requiring calcium carbonate are situated at a relatively close distance. The studied concept uses ammonium chloride as solvent for extracting calcium from the slag.
Calcium carbonate scale is one of the most common inorganic scales which deposits on the surface of oil and gas production facilities. This causes significant loss of production and ultimately leads to shut down of production lines if not properly managed.

Producing precipitated calcium carbonate (PCC) from steelmaking slag is a technology that contributes to the reduction of carbon dioxide emissions from iron and steel industries.
This study investigated calcium carbonate surface build-up under flow conditions, across a wide range of saturation ratio (SR) at 25oC and 70oC respectively. Both bulk induction time (tind) and surface induction time, which is referred to as scaling time (ts) were determined from capillary flow rig experiments.
This work aims to study the formation of calcium carbonate scale using a brine containing a calcium content close to that found in the pre-salt produced water on a carbon steel surface with different roughness levels achieved mechanically, using sandpaper.
