One of the most common production problems in geothermal fields is calcite (calcium carbonate) scale deposition. Calcite formed in the wellbore and in near wellbore region significantly decreases the…
Calcium carbonate scaling is experienced in nearly every geothermal field in the world. In severe cases, calcite formation in the production wells and surface equipment causes significant reductions in brine flow rates (Durak et al., 1993; Allan et al., 2019). This, in turn, can directly lead to a decline in output of the geothermal power plant.
The bio-mediated production of calcite crystals by calcinogenic bacteria has great applicable value for the restoration of deteriorated calcareous monuments, because of its high purity and coherency.
The production of calcite powder involves several steps, starting from the raw calcite ore, through crushing, grinding, classification, and finally drying. Here is a general process flow and the equipment involved:
Gypsum technology that offers the right calcination process for your gypsum raw material and for quality gypsum plaster production. Learn More.
The formation of mineral scale is a complex problem during the oilfield operations. Scale inhibitors are widely used to prevent salt precipitation within reservoirs, in downhole equipment, and in production facilities. The scale inhibitors not only must have high effectiveness to prevent scale formation, but also have good adsorption–desorption …

The antiscaling simulation, equipment design and experiment is studied. ... Geothermal wells in the Mindanao geothermal production field experienced calcite deposition causing output declines of 0.6 MW/month, an attempt to inhibit calcite deposition was made by Ramos-Candelaria et al. ...
Calcite's name comes from 'chalix' or 'chalx', which is the Greek word for lime ('calx' in Latin). For over 5,000 years, calcite has been used to manufacture lime (CaO, calcium oxide). Although the equipment used to do this has changed across the centuries, the basic process remains the same.
This paper has presented a mini review of previously published articles dealing with bio-cement production using enzyme-induced calcite precipitation (EICP) technique. EICP is a biological, sustainable, and natural way of producing calcite without the direct involvement of microorganisms from urea and calcium chloride using urease …
Calcite solubility also decreases with decreasing temperature (at constant CO 2 partial pressure). Halite scaling is also a self-scaling process. The drivers are falling temperature and evaporation. ... A review of the iron sulfide chemistry and phases occurring in production equipment is contained in Nasr-El-Din and Al-Humaidan ...

During cement production, calcite acts as a fluxing agent, lowering the melting temperature of raw materials, thereby conserving energy and enhancing …
Calcite is also used in the production of lime (calcium oxide) through the process of calcination. 7. Acid Neutralization: Due to its reactivity with acids, calcite is used to neutralize acidic substances. In industries like agriculture and wastewater treatment, calcite is added to balance pH levels and reduce the acidity of solutions.
Optical equipment: Calcite is used in polarizing microscopes and optical equipment due to its birefringence properties. Comparison. In summary, halite is used for de-icing, food preservation, chemical production, and water softening, while calcite is used in construction, agriculture, glass production, and optical equipment. Environmental ...
