Bleaching clay is then mixed with the pre-bleached oil, bleached and filtered in a clean filter. DoublePass bleaching is the most efficient process for reducing bleaching clay consumption and oil losses. Packed bed bleaching is a less common process that pushes the oil through a series of filters pre-coated with a bed of fresh bleaching clay.
PERCOLATION PROCESS CLAY Activated Fuller’s Earth is also used in the percolation filter process is in the granular form, this process is usually used for light colour oils like base oil distillates, mainly to improve it UV and PNC values.
The commercial product is prepared in granular form for use in the percolation process on petro- leum oils. For the most part, bleaching clay is used commercially in the de- colorization of animal, vegetable and petroleum oils, fats and waxes. It is applied in two ways: (1) by the percolation method and (2) by the contacting method.
Bleaching: The selective removal of pigments from oils and fats by adsorption on clay, specially chosen and activated for specific effects is a term known as bleaching. PERCOLATION PROCESS CLAY Activated Fuller's Earth is also used in the percolation filter process is in the granular form, this process is usually used for light colour oils...
Once the bleaching process is completed, filtration is done to the crude oil. The purpose of filtration is to remove the spent chemicals. The clay is filtered either on Plate Type Conventional Filter Presses or on Vertical Pressure Leaf Filters. Clean bleached oil is stored in Bleached

The best naturally active clays, treated slag, and various synthe~.ic bleaching media are considerably lower in bleaching power. A few clays may be prepared in granular form from the percolation process of bleach- ing. A few bentonites sl~~e in water get price

Silicate/clay bleaching dual filtration bleaching [1]. Figure 7. Countercurrent bleaching system [7]. Figure 8. Double-pass bleaching system [8]. Improved Oil Quality. Bleaching is the physical and chemical interaction of an oil or fat with bleaching earth to improve its quality. One definition of quality is “to reach a level of excellence.” However, with respect to oil specifications
3.4. Bleaching Evaluation. The bleaching assessment for the natural clay as evident from Table 3 is indeed very poor with a colour reduction of 9.091%. Upon activation with increasing HCl concentrations, there was increase in the Lovibond colour reduction from 9.091% to 27.275% as the concentration of the HCl used for activation varied from 0.2 M to 3.0 M as aptly displayed in Figure 3.

26.12.2015· Bleaching clays are activated to varying degrees via interaction with acids ranging from completely natural clays to highly acid-treated clays. Directionally the benefits to having increased adsorbent activity and/or impurity removal (i.e. bleaching efficiency) improve as the clay acidity of a base mineral is increased (pH lowers with limit approaching 2 pH). The advantages for an activated
EP Engineered Clays is a global leader in engineered products derived from industrial minerals that include bleaching clays, mineral adsorbent technologies, and catalysis. These high-quality products are used in the oleochemical industry for edible oil and biodiesel purification, aromatics purification, solid acid catalysis, BTX purification, nitrogen removal, copper refining, dimerization
Active bleaching clays result when bases iri the surfaces of the clay particles are replaced by the hydrog·en:_ and hydroxyl of acid. These are driven off as water by heat, leaving the open bonds essential for bleach ing. Bleaching power is at a maxirrn:un when only part of the bases are removed. If the leaching of bases is carried too far, the material de generates into an ordlnary clay

Clay soils can be expected to have an infiltration rate of 1 to 5 millimetres per hour or about 0 to 0.5 inches per hour. Compared to the infiltration rate of a loam soil (10 to 20 millimetres per hour 0.4 to 0.8 inches per hour) this is very slow. With an infiltration rate this low it is very difficult to grow most agricultural plants and grasses. This is because the infiltration rate is slow
