Product Description Waste Tire Pyrolysis Oil to Diesel Fuel Distillation PlantApplication:tyre oil to diesel and gasolineAdvantages:full auto,continuous production,save labour and energy,environmental friendlyCapacity:20TPD-200TPDBenji Company Speicial Technology and SolutionThe process mainly adopts multi-stage atmospheric pressure tubular furnace to rapidly and continuously dehydrate and continuously evaporate oil.The first stage, the treatment of raw materials of catalytic adsorption decolorization and deodorization by main fractionator;Meanwhile, the reflux ratio is controlled to improve the oil quality.The upper part of the column imixed oil and gas, which enters the second stage fractionation column after heat transfer.At the bottom of the secondary fractionating column is light diesel oil and nice quality diesel oil after heat transfer.The upper part is light gasoline oil fractionated from the top of the column, and the oil and gas is condensed into gasoline;The qualified oil components can be obtained by separate fractionation,which can solve problem of mixed oil fractionation difficulties. The heavy oil conveyed by the fractionator and column is deeply cracked in the horizontal continuous pyrolysis reactor, the oil slag will be coked,automatic timed slag discharge with machinary settings.Non-condensing dry gas is sent to heating furnace for combustion by treatment of multi-stage balance system and purification system .After multistage purification and adsorption treatment, the flue gas is discharged with environmental emission standard.The system can evaporate all the oil raw material throughly and totally.Flow ChartSystem ParametersProcess ProceduresFirst Step:Filter tyre oil to remove solid impuritiesSecond Step:Raw material dewatering in preheat column, low moisture-content material to reduce the heat dissipation, at the same time using the excess heat of gasifier discharged by flue gas to preheat material up to around 200-250 oC.Third Step:Preheated material evaporates in third grade gasfication column.Fourth Step:The oil and gas enters the catalytic heat transfer column to catalyze and adsorb for deodorization and decolorization of the materials, and at the same time the high temperature oil and gas and the high temperature heavy oil at the bottom of the tower are exchanged with the cold raw materials to save the heat energy.The heat exchanged oil goes into the preheating furnace for preheating.Fifth Step: The oil gas of catalyst tower goes into cooling system,derived diesel based fuel oil.Sixth Step:The heavy oil collected automatically at the bottom of the fractionator and the bottom of the three-stage column furnace was pumped to the reactor for cracking and continuous coking, and then discharged to the collection tank.Last Step:The recovered combustible dry gas is processed by the purifier and sent to the heating furnace for combustion.Flue gas is extracted and purified by induced draft fan. PS:All steps above processes continuously.Advantages of Our SystemFirst:Column furnaces are more efficient and faster.The surface area of column expansion furnace is very large, which is helpful to accept the heat of heating furnace quickly and widely.For the same fuel, the heating area of the column furnace is more than 3 times larger than that of the tank type reactor, so the evaporating oil tubular furnace is 2-3 times more than that of the tank type reactor, which has obvious advantages in energy saving and production efficiency.Second:Circulating heat transfer, special energy saving.This equipment is completely different to the traditional tubular furnace which it heats from the bottom to the top, heat goes up and down through the double-layer compact structure of the annular track, and through the inner and outer mezzanine pipe circulation to make full use of the heat and discharge then, energy saving about 25%.And because it is a pipe type heating, its surfacearea to accept heat is several times larger than the volumetric reactor, so also greatly improve the heat efficiency.Third:Safer production.The whole equipment is in a completely sealed situation, only a small diameter precision and highly sealed transmission device works,so whole system and process safety will be highly improved. Fourth:Double thermal radiation, especially high thermal efficiency.The reactor furnace is coated with far-infrared materials. The oil pipe can not only absorb the heat energy generated by heating the fuel, but also convert the fuel heat energy into far-infrared heat energy, resulting in an increase in temperature gradient. The radiation intensity is proportional to the fourth power of the temperature.Fourth:Pipeline series, especially high productivity.The column furnace connects many pipes in series to form a heating body.The material is heated and vaporized in a pipeline with length of hundreds meters.Depending on the diameter and length of the pipe, vaporization ability can reach from 50 tons to 500 tons,or even to thousands of tons per day and night.Production capacity is several times than the ordinary reactor.Fifth:Unique and efficient decolorization and deodorization design, derived better oil quality. A:New deep catalyst: the recombination can be fully cracked to make the oil with large molecular weight and dark color cracked, to meet the diesel 220 molecular weight, so as to get better oil products. B:Adopt decolorization and deodorization absorbent: it can decolorize the deep color oil and absorb the odor. C:Use of high efficiency additives: improve the smell of oil, and improve the antioxidant capacity of oil to achieve the purpose of oil stablization.Sixth:Through the above methods of catalytic refining and modulation,diesel dreived closes to the national standard with low cost to solve the product color and odor,Seven:Jet balanced low negative pressure operation is more reliable.It is beneficial to take proper low negative pressure of the reactor system in the pyrolysis process.Firstly,it is beneficial to the evaporative smoothness of cracked oil and gas.Second, To prevent oil and gas leakage.This technology can make the negative pressure absolutely stable, to ensure that negative pressure at any time is never exceeded, will not be dangerous because of excessive inhalation of air.Eighth:Recycling flue gas waste heat and waste gas recovery combustion and slag ablation technology, more energy saving.Nineth:The conventional reaction of pyrolysis at high temperature was changed to non-hydrogen-catalyzed reaction, and the oil conversion rate was higher.After using the new non-hydrogenation catalyst, the partial long chain macromolecules were fully cracked, and the oil yield was increased by about 2-3%.Tenth:Through constant repeated evaporation and gas phase purification device, acid and alkali free treatment.The heavy oil produced in the cracking process can be returned to the distillation, and through the decolorization and deodorizer in the catalytic tower to remove the odor effectively decolorization, thus saving the pickling process, thus reducing the oil loss of more than 3%.Eleventh:The single stage fractionation was changed to multi-stage fractionation, and the oil component separation was more complete.It is difficult to separate various components of oil effectively in single stage fractionator.Heavy oil, diesel oil and gasoline can be separated according to the temperature range of each component by multi-stage fractionator and temperature controllThe last:Intelligent automatic control is more accurate.The production process is basically controlled by electronic system. As long as the input of operation data, it can be operated automatically, which greatly improves the accuracy of operation and reduces labor intensity.
