“…The higher flow rates of 60 mL/min and temperatures of 35 O C could accelerate the reaction of Ca and CO 3 ions as a result of increasing mass scale of 0.1840 gr. It indicates that the increasing temperature could contribute the acceleration of scale formation [14] and the rising flow rates also lead to increase of mass scale [7,13]. However, the flow rate selected for this study is relatively low and considered as laminar solution (Reynolds number, N RE 175).…”

The Raman spectrum of CaCO 3 polymorphs calcite and aragonite: A combined experimental and computational study The Journal of Chemical Physics 140, 164509 (2014) Abstract. Scaling of calcium carbonate (CaCO 3 ) is commonly found in piping systems in oil, gas, desalination and other chemical processes. The scale may create technical problems, leading to the reduction of heat transfer, increase of energy consumption and unscheduled equipment shutdown. This paper presents crystallization scaling experiments and evaluation of the effect of Cu 2+ additives on the induction time and calcium carbonate transformation. The crystals precursors were prepared using equimolar of CaCl 2 and Na 2 CO 3 resulted in concentrations of 3000 ppm Ca 2+ in the solution. The Cu 2+ in amounts of 0, 1 and 10 ppm was separately added in the solution. The flow rates (20, 35, and 60 mL/min) and elevated temperatures (27, 35 and 45 0 C) were selected in the study. The induction time for crystallization of CaCO 3 was observed by measuring the solution conductivity over time, while the phase transformation of calcium carbonate was examined by XRD method and SEM/EDX. It was found that the conductivity remained steady for a certain period reflecting to the induction time of crystal formation, and then decreased sharply afterwards,. The induction time was increased from 34 and 48 minutes in the presence of Cu additives (1 and 10 ppm), depending on the flow rates and temperature observed. In all the experiments, the Cu 2+ addition leads to the reduction of mass of crystals. Apparently, the presence of Cu 2+ could inhibit the CaCO 3 crystallization. In the absence of Cu 2+ and at elevated temperature, the crystals obtained were a mixture of vaterite and calcite. In the presence of Cu 2+ and at elevated temperature, the crystals formed were aragonite and calcite. Here, the presence of Cu 2+ additives might have controlled the crystal transformation of CaCO 3 .

“…Further, several factors influencing the formation of calcium carbonate scale may include flow rates and the presence of impurities or additives [7]. In this case, metal ions such as Zn 2+ and Cu 2+ have been commonly used to control the growth of the calcium carbonate scale [8,9].…”

Abstract. Vibration in many industries commonly generated by the operation mechanical equipment such as extruder, mixer, blower, compressor, turbine, generator etc. Vibration propagates into the floor and attacks the pipe around those mechanical equipment. In this paper, the influence of vibration in a pipe on the CaSO 4 scale formation was investigated to understand the effect of vibration on the kinetics, mass of scale, crystal phases and crystal polymorph. To generate vibration force, mechanical equipment was prepared consisted of electrical motor, crankshaft, connecting rod and a vibration table at where test pipe section mounted. Deposition rate increased significantly when the vibration affected to the system i.e. 0.5997 and 1.6705 gr/hr for vibration frequency 4.00 and 8.00 Hz. The addition 10.00 ppm of citric acid declined the deposition rate of 8 Hz experiment from 3.4599 gr/hr to 2.2865 gr/hr.

Calcium carbonate is commonly precipitated as a scale in the transportation pipes of water. The presence of this mineral deposit becomes problematic, because it can block the pipes and lead to a decline in piping performance. Calcium carbonate precipitation from the synthetic solution was experimentally investigated in the present study. The aim of research was to predict the occurrence of precipitates and characterize the scale precipitated from the solutions. The synthetic solutions were prepared using CaCl2 and Na2CO3, which was mixed with distilled water (H2O). The concentrations of Ca 2+ at 2000, 3000, 4000 and 5000 ppm. in the solution were adjusted and the solution flow in the Cu pipes at the different flow rate of 30, 40 and 50 ml/min. It was found that in all the experiments, the conductivity decreased abruptly after a certain induction period. Higher temperature produced more mass of the scale indicating that the increasing temperature promote scale formation. SEM analysis showed that the scale was rhombohedral, while EDS revealed that the elemental composition of the scale consisted of Ca, C and O. The crystalinity of the scale was found to be mostly calcit as shown by the XRD
