The adsorbent to purify the transformer oil is activated alumina and silica gel. The XR101 activated alumina to purify the transformer oil is good performance.
The XR101 activated alumina pressure-changing oil adsorbent is white spherical porous particles with uniform particle size, smooth surface, high mechanical strength, strong hygroscopicity, no swelling and no cracking after being absorbed, and is non-toxic, odorless, insoluble in water and ethanol.
Under certain operating conditions and regeneration conditions, the product has a drying depth of up to -70 degrees below the dew point temperature. This product can be used as a fluorine removal agent for high fluorine drinking water (except for fluorine capacity), and cyclic alkane in alkylbenzene production. Defluorination agent, deacidification regenerant for transformer oil, used as a desiccant and purifying agent in the industries of oxygen production, textile industry, gas drying in the electronics industry, and drying of chemical instrumentation, petrochemical drying, etc. Up to -40 degrees), etc., pressure swing adsorption in the air separation industry (dew point up to -55 degrees). It is a high-efficiency desiccant for deep drying of trace water. Ideal for use in non-thermal regeneration units.
The note of transformer oil adsorbent:
Selection and dosage of pressure swing oil adsorbent
The adsorbent should have the characteristics of being porous, strong in activity and strong in acid absorption, so as to adsorb moisture, peroxygen compounds, organic acids, carbonyl groups, etc. in the oil, which are harmful to transformers and oil. They are spherical and rod-shaped irregular porous solid materials, and have the following requirements for their properties:
1 water absorption rate > 20%;
2 acid absorption> 5mg (KOH) / g (silica gel);
3 moisture content <0.5%;
4 appearance is milky white.
Therefore, the adsorbent should be dried and sieved before being added to the oil purifier.
The amount of adsorbent is determined by the total mass of the oil. When using acid-removing silica gel, it is about 0.75% to 1.25% of the total mass of the oil, the smaller capacity transformer uses a large number; the large-capacity transformer uses a small number. When activated alumina is used, it is about 0.5% of the total mass.
Choose activated alumina, please choose the right activated alumina!
