Calcium sulphate is one of the major fouling that lead to serious operating problems in industries. The mitigation of calcium sulphate scaling by physical water treatment (PWT) in an operating heat
Calcium Sulphate Fouling in Plate Heat Exchangers [Show full abstract] of a heat exchanger plate. The calcium-based salts are general form of scaling such as calcium sulfate or calcium carbonate and its problematic because these calcium-based
In this research the artificial calcium carbonate deposit on different material surfaces is considered as it is one of the major constituents of the most scales found in heat exchanging equipment.
Calcium carbonate scaling in a plate heat exchanger in the Nov 01, 2003 · Scale formation of CaCO 3 in a plate heat exchanger is investigated in the presence of various types of added particles under isothermal conditions. The parameters examined include the degree of supersaturation, the type of particles, the flow velocity, the particle concentration and the direction of flow inside the heat exchanger.
Usually, the fouling layers of deposits on the surfaces of heat exchangers are made up of calcium carbonate (CaCO 3 ), calcium sulphate (CaSO 4 ) and calcium silicate (CaSiO 2 ).
Calcium sulfate dihydrate (gypsum) scale formation on heat Jun 01, 1988 · Supersaturated solutions of calcium sulfate were prepared in a double-walled, water-jack- eted crystallization cell of about 1000-ml ca- pacity fitted with water-cooled condensers. The heat exchanger U-tubes of about 40 cm in length and 1.0 cm in outer diameter were made of brass, copper, or
corundum powder. For handling reasons the calcium sulphate concentration was lowered to 0.0275 mol/l CaSO4 in comparison to the batch experiments. The calcium carbonate concentration was in all experiments constant at 0.005 mol/l CaCO3. The solutions were prepared as described before. The heat
Fouling characterization of calcium carbonate on heat Apr 01, 2021 · 1. Introduction. Calcium carbonate (CaCO 3) fouling is widespread in industrial thermal systems [1,2].When hard water is used as the circulating fluid for heat transfer in a heat exchanger, the insoluble inorganic CaCO 3 salt with a negative solubility precipitates on heat transfer surface to form crystalline fouling .This may increase the fouling thermal resistance and reduce the
Jun 15, 2017 · These fouling layers usually contain calcium carbonate, calcium sulphates, calcium silicate, etc. which possess commonly a very low thermal conductivity . Hence, it can decrease the heat transfer rate, increase pressure fluctuations in heat exchangers and introduce an overall loss of industrial output  ,  .
