Adsorbent – Used in the Purification of All Types of Transformer and Turbine Oil on an Industrial Scale Based on Processed Bauxite
Application:
The product is the result of thermal and chemical processing of mineral bauxite, which is used for the physical and chemical adsorption of various colored impurities and sulfur-containing compounds in used oils.
Product Introduction:
According to the definition of the IEC standard, the chemical treatment of oil is the removal of any polar and chemical contamination of the oil, including acids, aldehydes, ketones, esters, and aromatic compounds. This process improves the chemical parameters of the oil, including neutralization number (acidity), surface tension, loss coefficient and oil color.
The oil after purification must meet the criteria and conditions described in the IEC 60296 standard.
Technical Specifications:
The adsorbent must have a high specific surface and porosity so that it can adsorb a large amount of impurities in the oil. In addition, the adsorbent should have high thermal stability so that it does not lose its structure in different stages of adsorption and regeneration and maintains its efficiency. The second aspect of the design is the adsorbent regeneration system, in which the amount of oxygen needed for regeneration should be determined according to the structure and type of pollution, and the regeneration control and monitoring system should be designed accordingly. The regeneration process starts by heating the upper part of the adsorber to the ignition temperature of the polluting compounds and then injecting air, and then this process of burning continues along the adsorber bed. Controlling the temperature profile during the regeneration process is very important, and if these conditions are inappropriate, the regeneration process will either stop, or too much heat will be produced and the adsorber will be damaged. The adsorbent used in this product is Active Alumina, which is prepared from the natural source of bauxite. For this, an acid leaching step with hydrochloric acid is performed to remove impurities of iron (hematite), calcium and magnesium, and then two heating steps are performed. Bauxite is first transformed into boehmite and then into gamma alumina or active alumina with an average surface area of 150 cubic centimeters per gram of adsorbent. Next, this product reacts with acid and its main impurity, i.e. iron, is removed.

Application:
Bentonite as a porous material is easily and abundantly found in nature. The possibility of using it as an industrial adsorbent and catalyst always exists and this field is the subject of many researchers› discussion. Activated bentonite is used as an active absorbent soil or color removal soil in various industries due to its specific surface area and high surface acid strength. The presence of olefins in aromatic compounds (benzene, toluene, xylenes) even in very small amounts can make these valuable intermediates of organic and petrochemical synthesis lacking desirable characteristics; Because under the relatively harsh conditions required for aromatics to continue industrial reactions, olefins, which are more reactive than aromatics, contaminate catalysts or create unwanted byproducts. On the other hand, since the amount of aromatic compounds in crude oil is much less than the increasing industrial needs, these valuable compounds are synthesized by the catalytic conversion process. In such a process, some olefin is inevitably produced. Although most of it is separated by distillation and solvent extraction, small amounts of olefin remain, and the deolefinization process by means of solid beds of activated bentonite is the only economic method for its complete removal.
Application:
All the mentioned impurities are absorbed by chemical adsorbents and removed from the feed stream or output product.
