Feasibility study report and take fuel oil
Times the background and significance of the project development
With the rapid development of the plastics industry, the application of plastic products more widely, have penetrated into various fields of national economy and people's daily life. It can be said that no other materials like plastic, so a wide range of uses. Plastic with its own unique properties, such as light weight, high strength, easy processing, excellent electrical insulation, thermal insulation, and the chemical corrosion, has become one of the pillars of modern industrial materials, and has played in the national economy an increasingly important role. However, it is precisely because some of the excellent performance of the plastic, resulting in waste after use (or post-consumer), non-perishable, over time, a serious impact on the Earth's ecological environment has caused a world of great concern. The total amount of the global plastics already over 100 million tons, also nearly 10 million tons of plastic products, and has a 13% annual growth rate of the rapid growth of the total amount of waste plastics will rise dramatically, the conflict between environment and development will increasingly more prominent, and therefore the management of plastic waste has become can not be delayed.
The most simple approach for plastic waste landfill and incineration. Landfill need to take up a lot of valuable land resources, but also pollute the surrounding environment and groundwater systems: simple incineration also harmful emissions and residues can not be recycled waste plastic combustion produce a lot of heat of combustion caused a huge waste of energy , both not good policy. How to deal with plastic wastes, has also become a common research and a subject of concern of the countries in the world and all levels of government. Since the 1990s, domestic waste plastics into fuel oil began to be widely appreciated. .
Japan's Mitsubishi Heavy Industries, the development of decomposer the process of production of fuel oil
First crushing waste plastic into a certain size, after drying hopper into the melting trough (300-350 ° C) melting, and then into the 400-500 ° C decomposition tank to slow decomposition, each slot by the hot air heating. Tarry or waxy high-lighted material in the condenser condensate after the separation required to return to the decomposition tank and then heated to decomposition into low molecular weight substances. Low composition of the steam in the condenser is separated into condensate and non-condensable gas and condensate separation of recoverable oil through the oil-water separator. Low oil viscosity, high heat, freezing point below zero degrees Celsius, but ignition wide, the ignition point is extremely low, is a high quality fuel oil is best used to remove low ignition components. The non-condensable gaseous compounds through the absorber out of hydrogen chloride can be used for fuel. Part of the recovery of oil and gas can be used as a hot air heating energy in each slot.
University of Hamburg, Germany, the development of waste plastic fluidized bed thermal decomposition reactor for fuel oil.
The waste plastic flow from the hopper, the conveyor by the screw feeder into the electric reactor, fluidized layer of about 20M deep. Per hour the 50L liquefied heating, thermal decomposition gas in an electrical precipitator dust, in the depth of the cooler part of the liquefied, non-condensing gas as liquefied media back to the reactor and then.
University of Kentucky fuel chemist Ban 迪塔格希艾 invented the end of the zeolite molecular sieve for the reminder agents of all kinds of plastic mixed into the sand bath, and then this slurry into the reactor, the hydrogenation pressure and then heated to cause polymer plastics break down into high quality fuel oil.
More than three foreign representative of the waste plastic oil equipment, waste treatment in the production process can meet the environmental requirements of their respective countries, but investment in more than 20 million yuan, the daily output of only about 5 tons of fuel oil, can not promote, does not have commercial value.
Waste plastic oil equipment host the Chinese mainland used with vertical fixed processor, the process is as follows: waste plastic artificial joined first cracking the top of the processor, and then closed the feed inlet, then the processor end of the coal or firewood is heated slowly, cracking processor usually has a volume of 5 cubic meters, feeding one tons, it normally takes 12 hours had finished a furnace. After the stop 12 hours. Fully decline in processor temperature, open the slag processor Ministry of subordinates under the slag door, mouth feed from the processor to feed into the next cycle.
Vertical refining processor equipment, waste treatment in the production process can not meet environmental requirements, and production is low, do not have the continuous production capacity, and would like to have the economic benefits of joint production requires more refining processor.

Third, the product and raw materials market
With the rapid development of world economy, the increasing shortage of oil of momentum since the 1990s, 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 seek new sources of energy has become a concern of the countries in the world. China has vast territory, large population, and With the rapid development of market economy, the vehicle, the popularity of the machinery, the oil market demand constantly increases, our country has been the oil-exporting countries to oil-importing countries. The second half of 2010, According to the news released by the China Petrochemical Corporation, in addition to the domestic production of crude oil needed in a foreign country imports eight thousand barrels of crude oil to meet domestic market demand. 2010, international crude oil prices again rose, and a barrel of crude oil has exceeded $ 100 / barrel (OPEC offer) in February 2011.
Refining of raw materials to ensure that the source of it?
For example, in Henan Province, a year from the garbage and recycling companies to recycle 400 tons of waste plastic. The development of industry and transportation, a lot of waste oil urgently.
Chinese mainland, according to a medium-County statistics, the annual consumption of fertilizer, phosphate fertilizer, cement and other bags of various colors of plastic film, snack, foam packaging board, a variety of food packaging films, bottles, boxes, each rubber, plastics, waste oil, and its total of about 12,000 tons more than one county to establish four year deal with 1500 tons of waste plastic oil refinery, the raw material is no need to worry about.
