One: the traditional bleaching method of the drawbacks:
As we all know, the new refining, diesel oil containing alkaline nitrogen and other glial, impurities, met the air will quickly oxidize discoloration, so that the impact of oil quality. However, so far, all steam, diesel decolorization,In addition to the removal of all the basic use of strong acid mixing, sediment treatment, serious loss of oil, heavy sediment pollution, which is recognized as a drawback.
Second: the new catalyst decolorization mechanism:
Diesel oil decolorization completely change the traditional method, the oil by a filter can be clear and transparent to the color of the national gasoline and diesel color standards. "The oil discoloration is mainly unsaturated olefins with double bonds, which are extremely unstable and easily oxidized." The new diesel catalyst has a hydrogenation conversion effect. When the oil is catalyzed by atmospheric pressure, the catalyst releases hydrogen ions The unsaturated olefins are hydroalkylated to convert them into a single-bond saturated hydrocarbon with strong stability, thus achieving the stability of the oil.
Three: diesel decolorization production equipment:
A diameter of 0.6 – 1.5 meters, 1 meter high cylinder catalytic tower, cost about 400-1000 yuan.
Four: diesel catalytic decolorization method of use costs and benefits:
Generally about 2% per ton of oil that is 20 kg catalyst, about 2 yuan per kilogram, priced at 40 yuan, only the loss of 4-5 kg of oil (less than the acid adsorption sediment loss 10-20 times Right), generally treated oil as a result of color standards, selling prices can be higher than 300-800 yuan, the calculation:
Daily processing 10 tons × 500 yuan increase in profits = 0.5 million.
Day processing 100 tons × 500 yuan increase in profits = 50,000 yuan. Visible profits and considerable.
Five: diesel catalytic decolorization of the environmental evaluation:
Not a lot of dirty slag discharge, no exhaust odor. Is an environmental project.
Six: diesel catalytic decolorization method Scope:
It is suitable for the decolorization and deodorization of the black and baking diesel oil produced by the small and medium-sized refinery. It is suitable for the decolorization of the black-smashed diesel oil in the middle and late stages of the refinery. It is suitable for the decolorization of the black-baked diesel oil In addition to taste, suitable for refineries, oil companies have been oxidized black oil decolorization, but also for lubricating oil and black base oil decolorization in addition to taste, more suitable for waste oil, refining black smelly diesel decolorization addition to Taste the most suitable for refineries, as long as the oil and gas cooling tower under the tubing placed a catalytic tower can be. For the already polluted dirty oil, pretreatment into the catalytic tower has the same magical effect.
Seven: diesel oil decolorization treatment of oil has the following characteristics:
1, less loss, the taste of pure oil, color up to the national standard. With decolorizing deodorant cleaning out the oil, the slag rate is much less than the old way to wash the oil residue rate. Refined diesel color will not be reduced, and the longer the placement, the color but the more clear, the more bright, especially clear and transparent. The taste of the oil is also relatively pure.
2, low cost, wide application. Due to less slag, so the cost is also reduced accordingly. The agent can not only wash the oil refining of small oil refining, but also deal with lubricants, minus the first line, minus the second line of oil, waste oil, and other refined diesel oil and the old way can not wash out the oil, the application of a wide range. 3, the provincial workers, saving time, effort, a substantial increase in the rate of oil wash, and no heating, pressure, easy to operate. With the decolorization of deodorant than the old way to improve the efficiency of 2-3 times, greatly save the problem is not separated, can be processed for many years. 4, to solve the waste disposal problems, with the agent washed out of the residue, no bonding, no caking, no solidification, waste can be reused. If the sales, but also than the old way to wash out the waste more money to solve the environmental problems. 5, decolorizer after inactivation of bleaching agent can be used to restore the activity of steam purge, air-dried can be applied after 3-5 times. Fifth, the use of decolorizer added to the filter, so that black diesel through a certain degree of decolorizing agent, the chemical reaction to black oil decolorization. Can be atmospheric pressure gravity.
