Continuous automation of coal tar refinery to refine fuel oil, new technology First, the coal tar refining the raw materials of diesel 1, coal tar refining Coal tar is the liquid products of coal in the process of dry distillation and gasification. According to the different available the following tar carbonization temperature and method: A low temperature carbonization tar, referred to as the low-temperature coal tar (of coke by-product of 450-650 ° C temperature conditions); B, Low temperature and Wen Fasheng furnace tar, referred to as the low-temperature mixture of oil (in the 600-900 ° C temperature coking by-products); C, the temperature vertical furnace tar, referred to as the medium temperature coal tar (of coke by-product of 600-900 ° C temperature conditions); D, high-temperature tar, referred to as the high temperature coal tar (of 1000 ℃ temperature coke by-products); Coal tar flash point is generally 96-105 ° C spontaneous combustion point is 580-630 ° C; heat of combustion value of 35700-39000kj / kg. Regardless of the kind of tar with a pungent odor, dark brown viscous. The best coal tar can be used to refine the diesel is the freezing point of 21 ℃, low temperature coal tar in the proportion of 0.95, where the moisture content is less than 2%, containing about 4% of the dry gas containing refined tar, diesel components at 75 - about 80 percent, another by-product heavy oil 10%, the total yield and then about 90%. Medium temperature coal tar refining of fuel oil can be used as raw materials. Such tar to do the processing of diesel fuel nuclear fuel raw materials with good economic benefits. 2, carbolic oil refining. Carbolic oil is a component of 170-210 ℃ Wash oil refining. Wash oil belongs to the components of coal tar in the 230-300 ° C temperature range; 4, anthracene oil refining. Anthracene oil is a component of 300-360 ° C temperature range. The above materials can be used to extract the fuel oil. Second, the nuclear fuel oil of refining diesel main technical indicators Beige (or orange), coal tar, diesel and fuel oil was crystal clear, high calorific value, can be widely used in industrial, heating oil fields, the partial substitution of diesel-powered use. Technical indicators are as follows: No. Name the oil comparison diesel A cetane number 4645 2 flash point 5555 Three water traces traces 4 mechanical impurities None None 5 Corrosion of a (standard) a (standard) 6 color beige yellow light Third, the production of major equipment Continuous oil into the slagging reactor, secondary cracking of the reactor, cooler, bleaching tank, agitator, adsorption tank, flame arrester, oil pump, oil-water separator and so on. Fourth, the oil refining process route Feedstock pretreatment --- continuous feed --- continuous vaporization (the liquid catalyst) ---- catalytic fractionation (fixed bed catalytic cracking depth) --- Cold suspect - oil separation - impurity (add go to miscellaneous agents) - refined (additive) - refined oil Fifth, the technical characteristics Continuous production and high efficiency. This technology is cleverly designed, originality, and the entire production process is continuous, Two, two-phase catalytic oil. This technology using a variety of depolymerization agent, FCC agents, in-depth comprehensive cracking reaction of the raw material oil from liquid to gas, the role of the zeolite, oil-molecular-weight carbon structure are close to diesel, as can be refined after The ideal alternative to fuel oil, equivalent to 0 #, -10 # diesel oil. Third, the operation simplify the more environmentally friendly. Feed and slag are fully automatic operation, greatly reducing the intensity of production, especially in the hermetically sealed state, safe and environmentally friendly. Fourth, a reasonable safe vehicle recovery unit, and significant savings in fuel. 6, the main production equipment Continuous vaporization, slagging reactor Secondary cracking reactor Cooler Solid-gas separator Non-condensable gas recovery system Impurity cans Refining tank Filter Catalytic tower Fractionator Other Seven, economic 2, the cost of production (Raw materials, coal tar, for example, equipment to JJ - 2 type, for example) JJ - 2 economic benefits analysis a, 6 tons of coal tar (90%) of the oil yield of 6 t * 2400.00 yuan / ton = 14400.00 yuan b, coal, 0.15 tons * 800.00 yuan / ton * 6 tons of crude oil = 720.00 yuan Hydropower: 20 kilowatts / hour * 0.70 yuan / kW * 15 hours = 210.00 yuan d, chemicals 100.00 yuan e, worker 2: Wage 50.00 * 2 = 100.00 yuan f, equipment depreciation, 100 yuan g, taxes (Note) environmental projects duty-free h, 100 yuan Total: 15730.00 yuan j, the day output (JJ --- 2 devices) JJ --- 2 devices Nissan 5.4 tons of refined oil, you need coal tar, plastic six tons of crude oil. k, gross profit Finished 0 # diesel price is 8000.00 yuan per ton. Production of fuel oil instead of 0 # diesel oil is used in industrial heating fuel gun. Homegrown fuel oil 4000 yuan per kilogram calculation. JJ --- X-type daily turnover of 5.4 * 4000 yuan / ton = 21600.00 yuan Daily profit 21600.00 yuan / of -15730.00 yuan / day = 5870.00 yuan / day Monthly profit of 5870.00 yuan / day * 25 days = 146,750.00 yuan Annual profits (ten months) 1.4675 million yuan. Investment recovery calculation Monthly profit of 146,750 yuan, the equipment into the factory within 50 working days to put into operation, the normal production of short-term recyclable entire investment. VIII Conclusion Coal tar is a byproduct of the coke carbon and production of gas, very rich in resources. In particular, Shaanxi Province, Shanxi Province, Shandong Province, Anhui Province, Inner Mongolia, Xinjiang, Guizhou Province, Yunnan Province, such as the large number of coal tar; many major cities are also a large number of processing gas and the byproduct of coal tar and other oil products. These resources have not yet been fully deep-processing in directly for the heavier fuel burning as fuel. If they are refined alternative to diesel fuel would be great value, and create greater economic benefits. The Company after many years of research and development, made use of coal tar coal tar class diesel extensive experience in application or number of national patents, for investors willing to provide advanced technology, allows you to black oil into gold.
