Waste lubricating oil analysis report on the feasibility of

Significance of a project development background:
     
With the rapid development of the waste oil waste plastic scrap tires oil refining industry, the application of the production of fuel oil, and has penetrated into various fields of national economy and people's daily life. But at the same time due to the rapid development of the industry and practitioners to increase the prices of raw materials also greatly improved.
    
Not reduce raw material costs on the basis of how to improve the added value of the fuel oil? The easiest way is to waste oil, waste plastics, tires production of crude oil distillation again (or called distillation). By distillation after the oil is usually yellowish or reddish, the major technical indicators can reach the standard of GB diesel, the price increase in crude oil per ton of 2,000 yuan. Production of this renewable fuel oil device there are two directions to choose one investment of hundreds of millions of large petrochemical refining equipment, and the other direction is more popular investment of only 2 - 10 million of soil furnace. Soil furnace efficiency and security, environmental protection is rather poor. How to invest, some weaknesses, and overcome the soil furnace is an important topic.
      
Currently used in soil furnace with horizontal fixed processor, process as follows: waste oil, waste plastics, waste tires generated by crude oil first cracking the top of the processor manually join, and then closed the feed inlet, and then to deal with the bottom of the coal or wood for fuel is heated slowly, cracking processor usually has a volume of 20 cubic feed of 15 tons, generally at least 5 - 7 days to Lianwan. After the stop at least 24 hours, cracking processor cooled down sufficiently open mouth of the processor slag slag. From the processor feed inlet feed into the next cycle.
    
Our company is committed to refining gasoline, diesel and oil renewable base oil professional research for more than ten years of waste lubricating oil, waste oil refining regeneration plant (formerly known as the ECOTECH) is a high temperature pyrolysis of waste oil to make it transformed into a 0 non-standard diesel (known as a technique of approximation of the natural and the diesel fuel oil), the technology is the most important component is a group of high-temperature pyrolysis furnace, a set of distillation, and a group of high-pressure air-cooled condenser, making 85% to 95% of the hydrocarbons in the waste oil refining renewable technologies can waste oil separated; cracking furnace operating temperature and process appropriate separation of diesel oil steam and refinery crude oil distillation tower Topping, the Process by The process is very similar to the isolated product quality and 0 # diesel oil is also very similar. Main solution to the three difficulty affect the efficient development of the project, namely: quality - Size --effectiveness; in the country to do this we must:
     
First, the establishment of a unique quality assurance system, successfully developed exclusively for the pyrolysis of waste lubricating oil hydrogenation refining agent, catalyst, the preparation of a special catalyst, bleaching agents, deodorant and production lines, the formation of styling products.
     
Second, determine the scale of investment - the most economical, the proliferation of urban and rural waste lubricating oil density determination of the lowest cost of collection, transportation, scientific design of the 5 tons of diesel Nissan factories scale, their equipment all-day production, closed clean run, oil-producing and oil quality is good, the outbreak of oil has a strong, resistant to burning. The oil conversion reached 75-90%, 1 ton of waste oil can produce 1600-1800 pounds of diesel and 100 kg of natural gas as a fuel burned in the furnace or recycling, production of secondary pollution. This technology that is turning waste into wealth to solve the waste of oil pollution of the environment and the development of a new energy, their social benefits far greater than the cost-effective. Regeneration of waste oil is an environmentally friendly high-tech industries because of its economic benefits, and the end of high value-added products, the end product sales is easy, in principle, as long as the technology used is correct, no matter where to invest and build factories were all very The forward-looking and high-profit industries. According to incomplete statistics, China's daily production of about nearly a thousand tons of various waste oil waste lubricating oil, the production is so large, the recovery rate is very low, development and utilization of waste oil to produce diesel prospects of the vast, rich resources, but also state support object, and the production process is simple, the technology easy to master, intuitive and suitable for factories, collective, personal production and management. State Environmental Protection Administration will waste oil as one of the top three priorities of the 21st century in the field of environmental protection control, waste oil will be the most potential for development of new industries in the 21st century.
     
Third, the technology is consummate, the mode of operation is unique, low-cost, high efficiency operation to ensure that the project profitable.
      
My company after several years of repeated research and experiments, combined with the advantages of large petrochemical refining device, weaknesses, based on reality, starting from the actual conditions, after a long period of scientific and technological research, we designed and launched a continuous production of waste lubricating oil refining diesel equipment and waste oil purification technology.
Second, the device features
    
The the Huadu long Golden Machinery Co., Ltd. After years of research, the successful development of a waste oil refining diesel-leading technology, completely solve the traditional waste oil refining black diesel oil, high viscosity, high density, easily oxidized, odor, main index falls far short of such problems, its outstanding advantages are the following:
    
1, the entire device is small size, high output, easy operation, and continuous fuel continuous production.
    
2, the process is low temperature and atmospheric pressure, high safety factor, the proceeds of oil is light in color [yellow], low viscosity, low sulfur.
    
And efficient exhaust gas recovery system. In the refining process, can not be liquefied gases, these gases burning through two safety devices, water seal and gas nozzle fully, namely, the elimination of exhaust pollution, but also save a lot of fuel.
    
4, the burner uses domestic advanced anti-burn technology, the production process is running in a smoke-free environment, environmental effects, stack exit of the national emission standards.
     
Unique explosion-proof safety device that allows you peace of mind.
     
6, low power, high efficiency: multi-stage catalytic cracking production programs, improve the quality of the product. After multi-stage catalytic after the molecules are effectively directed to cutting, you can basically achieve the requirements of gasoline and diesel. Continuous operation and multi-stage heat exchanger technology, compared with the intermittent time more than 50% of the thermal equipment energy efficiency increased more than 200%.
     
7, the distillate of high yield: the more traditional methods, overall oil yield of waste lubricating oil can improve 10% or more. The unique strength synthetic catalyst allows waste oil refining diesel reduction rate of more than 95%.
    
Clean oily residue material evaporator can be oil distillation tailings evaporation, which compared with oil-bearing tailings emissions, overall oil yield of waste lubricating oil can be increased by 5% or more.
    
9, through the constant repeated evaporation and gas purification device, eliminating the need for acid refining process, soil washing, which can reduce more than 3% of the oil loss.
    
10, part of the light group can be light through the ultra-low temperature gas condensing unit, group of non-condensable gases, liquefied collection, compared with room temperature water-cooled, overall oil yield of waste lubricating oil can improve by more than 2%.
   
11, security: through PLC touch screen automation control system, can be safety hazards in advance to exclude. Multiple safety relief valve can be safety hazards for the release handle. In order to ensure safety in production, specially designed for the central control room, were set in the relevant parts of the production of a variety of instruments for tracking and monitoring, and timely production of all parts of the data reflected in the central control room, to keep abreast of, or adjust the status of the production process, found or irregularities that may occur in the production that can quickly make a disposal measures for non-safety phenomenon, that is accurate and timely exclude the possible security risks, to ensure production safety.
   
12, and environmental protection: the entire production process is basically in a hermetically sealed operation, there is no direct discharge of the phenomenon of the "three wastes". Oily waste gas combustion devices, enable the oily exhaust in the boiler to get the full heat release, the boiler exhaust the Green three filtering, lye spray device to achieve tasteless, colorless discharge environmental standards. Condensing water is recycled cooling mode, free wastewater discharge. Residue combustion through the combustion heat release, the final slag sales to brick factories, waste emissions.
   
13, short processing cycle: constant repeated evaporation and gas purification device, eliminating the need for acid soil washing refining process, raw materials, the same day can be processed into goods, the day of sale.
   
14, a full range of automated intelligent control: by PLC touch screen automation control system, the equipment full range of intelligent control, the data can be significant, controllable. Equilibrium relationship of the reaction temperature, reaction to the material accurately and smoothly, if the temperature fluctuated cracking degree of fluctuation, the temperature is too high there will be a lot of dry gas, non-condensable gas, thereby reducing the yield of the oil; and too low a temperature will result in cracking rate and extent of low-lysis is incomplete, the same cause low oil quality and yield.
   
15, take a closed production, pressure electric contact control, continuous production, safe and odorless products through the liquid phase catalytic gas phase catalytic, the finished product is not acid and alkali refined, light yellow, lower density, the carbon chain is interrupted in the 160-180 between full compliance with the diesel combustion standard. Equipment and technology degeneration strong catalyst proceeds of oil, gas, liquid instantly be sold, the savings depend on the pH, flocculation, and other cumbersome process, but also in the liquid phase catalyst, cracking a light oil and then refined to reduce costs.
   
16, the heating method is unique: an integrated approach of far infrared heating and coal heating, environmentally friendly and energy-efficient. This equipment in addition to the original car for the first time the device warm-up after the basic do not have another use coal or power of the material is heated, basically rely on self-generated in the production of heat and dry gas heating. Compared with the batch production techniques, each processing one ton of fuel oil can save about 40% of the cost of fuel.
   
17, the unique high-temperature feed: so far, generally small and medium-sized oil refineries usually use the vertical reactor or a horizontal reactor, production, raw materials, a one-time All reactor, the gradual heating of the approach to the material vaporization gradually evaporate, and then gradually cooling the slag. We have taken into raw materials under high temperature conditions, the process of discharge of the residue under high temperature conditions. Equipment from incoming oil, slag are the pipeline, at any time after the original car for the first time the temperature reached requirements a continuous feed, vaporization, catalytic cracking, oil, slag, as long as the equipment normal operation, the full realization of continuous operation, which greatly improves production efficiency.
     
18, various forms of slag. Will always be isolated from oil refining in a small amount of residue, these residues can dry residue into coke type, can also be in the diesel oil does not evaporate clean, so that as asphalt or other purposes. This selectivity can be more responsive to market demand, and get the best economic and social benefits.
Third, the product and raw materials market
    
With the rapid development of world economy, the increasing shortage of oil of momentum, energy has become a major factor restricting the economic development of countries, has proven oil on the global land 15 years after mining finished! To find new energy sources has become the concern of the world. China has vast territory, large population, with the rapid development of market economy, the popularity of the vehicles, machinery, oil market in constant growth, China has already become oil-importing countries from the oil-exporting countries. Early in 2006, according to the news released by Sinopec Group, China's addition to the domestic production of crude oil needed in the foreign imports of eight thousand million barrels of crude oil to meet domestic market demand. Refining of raw materials to ensure this? In Mainland China, the region in each county level or above, almost all waste oil refining crude oil factory waste plastic scrap tires. In addition, waste oil, waste oil and other waste mineral oils. Therefore, a county, a 1500 tons of refined oil refinery, the raw materials do not have to worry about.
