“…The same group later studied that modified nickel and copper surfaces and showed a copper-docosanoic acid and a PTFE coated nickel surface has lower surface energy (measured as contact angle) which in turn lead to significantly longer induction times (Yang et al 2000(Yang et al , 2002. Morizot and Neville (2002) investigated scale formation on a stainless steel surface coated with polycarboxyic acid and showed that the coating was highly effective in reducing scale formation.…”

This paper focuses on the complex problem of calcium carbonate scale formation on heated surfaces and the possibilities of controlling or reducing this problem. The development of scale is a multistage process and is affected by a number of factors, these include supersaturation, pH, temperature and flow velocity. Calcium carbonate deposition can be ameliorated by chemical, physical or biological methods with various level of effectiveness. These controls can be divided into three main categories: those that affect solubility, those that alter the growth mechanism of crystals, and those that change the potential of a surface to foul. One of the most effective methods of controlling crystallization fouling is the addition of chemical inhibitors to potentially scaling waters. There are a number of alternative non-chemical treatment options available, amongst these are the use of magnetic, electronic and electrolytic treatment devices. Scale formation is affected by the physical nature of the material on which it is forming, therefore it is possible to choose material to reduce scale formation. Each of these scale controlling methods has their advantages and a number of factors have to be considered before choosing the right option.

“…Scale deposition (e.g., CaCO 3 , CaSO 4 , BaSO 4 ) is a difficulty encountered in industry and domestic equipment such as heat exchangers [1], in cooling systems [2] and desalination plants [3]. It can cause important technical and economic problems [4,5] in various industrial processes.…”

International audienceIn this paper, the inhibition efficiency of two inhibitors, namely poly(acrylic acid-co-maleic acid) and polyaspartic acid, towards calcium carbonate scaling was evaluated using fast controlled precipitation (FCP) method and electrochemical quartz crystal microbalance (EQCM). FCP method gave some insight to the calcium carbonate precipitation in solution, whereas EQCM was used to study the calcium carbonate formation on a metallic substrate. It has been shown that these polymers were efficient to delay or to prevent nucleation/growth process, depending on their concentration. Moreover they significantly decreased the crystal growth rate. The FCP method showed that these inhibitors were very efficient at low concentrations (4 mg L−1) when no precipitation occurred. In addition, EQCM showed that the surface coverage of deposits on a substrate was reduced by the presence of these inhibitors at very low concentration (4 mg L−1). Scanning electronic microscopy and X-ray diffraction showed that the presence of these polymers modified the morphology of calcium carbonate crystal. In order to model nucleation/growth process of calcium carbonate on surface, mass–time transients were interpreted using a 3D model based on a nucleation following a Poisson law associated to vertical and lateral growth rates

“…The main reason of scale formation, which becomes related to degassing, evaporating and cooling, is the relative dissolubility of CaCO 3 . It is important to know the scale formation of mechanism and to understand it well in the process of choosing measures and cleaning method of mechanism [1][2][3][4][5][6][7]. The corrosion effect of geothermal fluid is related to chemical composition of medium very much.…”

Plant extracts have become important as an environmentally acceptable, readily available and renewable source of wide range of inhibitors. Tannins, a class of natural, non toxic and biodegradable polyphenolic compounds, extracted from plant sources are already used as corrosion inhibitors in aqueous media. This study investigates the inhibiting effect of Quercus robur and pomegranate peels extracts on st37 steel corrosion in geothermal fluid using the Tafel polarization method. It was found that the extracts act as good corrosion inhibitors for geothermal fluid. 250 ppm of Quercus robur oak extract was seen to have 90% corrosion inhibition efficiency. The values of pH, potential, conductivity, total hardness and Ca 2+ hardness, dissolved solid substance (TDS) and salinity of geothermal fluid were analyzed before and after the addition of extract into it. According to these analyses, increasing pH level more than 5 indicates that corrosion con structive aggressive ions (H + ) decrease. Furthermore the decrease of conductivity values as a result of the decrease of inhibitor concentration shows that corrosion slows down. Ryznar and Langelier Indexes are cal culated for AF11 well, reinjection and collected pools. The values of indexes show that geothermal fluid is corrosive and scale properties.
