Production processes, product performance Fullers Earth and the main performance characteristics

The characteristics of the treated oil decolorizing clay:

1, less loss of oil, pure taste, color reaches gb. Deodorant cleaning out the oil decolorization, the slag ratio is less than using the old methods of wash oil slag rate. The refined diesel color not only reduction, and placed the longer, its color instead of the more clear, more bright, very clear. The taste is pure oil.

2, low cost, wide range of application. Because the slag is less, so the cost is reduced correspondingly. The agent can not only wash with crude oil refining the small refinery, can handle the lubricating oil, vacuum first, second oil, waste oil refining diesel and for the old ways can not wash out the oil, suitable for a wide range of.

3, labor saving, time saving, labor saving, greatly improve the cleaning work rate, without heating, pressurizing, convenient operation. With oil decolorization in addition to taste agent than the old way of improving the efficiency of 2-3 times, greatly saves time, and solves the problem of wash oil cold old methods do not separate, can be long-term production.

4, to solve the problem of waste treatment, using waste residue, the elution is not bonded, non caking, no solidification, waste reuse. If the sales, than the waste old way to wash out more money, solve the problem of environmental protection.

Fullers Earth

In the edible and non edible oils and fats in the industrial production of bleaching earth, so-called used to remove from crude oil and fat colored and colorless pigment. Purification of the process of the adsorption attempt, oil and fat color and stability may substantially increase. Bleaching earth different types may be used to purify. The first group is composed of a high performance bleaching clay called (HPBE) formation. Strong mineral acids in HPBE by boiling temperature about the acid under leaching bentonite production. In order to obtain high performance bleaching earth, concentrated acid typically used to dry the starting clay matter basis of about 60 to 90 weight%. In the filtration of aluminum ions at the same time, other metal ions from the clay structure and the acid dissolved away. After the filter is formed in the activation period of salts, the acid must be separated from the products of clay by filtration, and the residual acid must be removed from the clay through sufficient washing. If the residual acid high level has been left in clay, quality of the bleached oil weakened. High level of residual acid adverse acid from fatty acid triglycerides in the oil free fat. During the acid leaching of clay, clay and residues from waste containing ionic salts. Such waste liquid must be by precipitation or further such as sewage treatment method to neutralize.

Advantages of the new type of Fullers Earth with high bleaching activity, which may be through the use of acid surface treatment has been further strengthened, for example by spraying acid solution to the clay material. Because of its high bleaching bleaching earth activated only a small amount of added to the oil to purify the purification degree required. In addition to the high efficiency of bleaching, bleaching clay is suitable for massive application should also provide high filtration efficiency and high capacity efficiency. High filtration efficiency of bleaching in a reasonable time period after the oil filter is very important. High efficiency of the remaining oil holding loss minimization in bleaching clay used in the oil is very important. In order to get the optimal bleaching earth, these three qualifications must meet all. Activated bleaching efficiency, filtration efficiency and capacity efficiency can be merged into bleaching clay allows evaluation of the total efficiency. Suitable for bleaching earth mass bleaching oil should therefore form a high total efficiency.

Introduces bleaching clay, performance and formation process

Bleaching clay is also called “bentonite”, “bleaching earth”, dominated by smectite group minerals. Common minerals include feldspar, gypsum, calcite, quartz and the incomplete decomposition of volcano tuff material. General pink, white, yellowish, grayish green color. The appearance of colloidal, low hardness, immersed in water to swell, no plastic, low refractoriness. Often the tuff or volcano rock in sea water or groundwater, by weathering in alkaline medium (pH=7-8.5) environment of deposition. Because it has strong absorbency and water swelling, so use in petrochemical fields, such as used in petroleum, oil, sugar, wine making, paper making, textile and other industries as a purifying agent and bleaching agent.

Bleaching clay mineral filter is always a tricky and long-term unsolved problems. Slurry by ultrafine grinding, grading and bleaching, must pay the economic price. If the filtering problem can not be solved well, not only directly affect the enterprise efficiency, waste of mineral resources, but also polluted water and environment phenomenon is very serious

Bleaching Clay

Clay is mainly composed of aluminous rocks, such as feldspar, pegmatite granite, porphyry, gneiss through long-term weathering, and often through the water transport and deposition, is a variety of fine mineral mixed body, its main chemical composition is SiO2, Al2O3 and crystal water. With the geological formation conditions are different, also contain a small amount of alkali metal oxide, alkaline earth metal oxide and metal oxides.

Most of the literature on clay will start to define or clay to some professional terminology to explain, this is very necessary, because the varieties and usage of clay is indeed much. Often the clay was classified according to Mineralogy, geology, chemical composition, physical properties of the cause or industrial purposes.

There are 3 ways: 1. The formation of clay minerals is related to weathering. Types and medium weathered rock conditions such as water, climate, landform, vegetation and time factors determine the mineral species and save or not. Hydrothermal and hot spring water in rock, can form the clay mineral alteration zone. ③ by sedimentation, diagenesis mineral formation clay. In modern or ancient sediments can sometimes be formed with industrial significance of kaolin, bentonite, palygorskite, sepiolite clay and clay rock.

Use of kaolin is mainly used for ceramic raw materials, papermaking filler and coating; mainly consisting of montmorillonite bentonite used as drilling mud, binder catalyst oil refining and bleaching agent, iron ore pellet and casting sand binder; palygorskite and sepiolite clay is the manufacture of salt mud quality raw materials, grease decoloring agent and absorbent.
