Description
Technical field
The present invention relates to recover the oil and the technology of refinery oily sludge processing, particularly relate to a kind of compound bio matter granular fuel preparation method.
Background technology
At present, conventional fuel generally is fossil fuels such as coal, oil, Sweet natural gas in the production.These fossil fuels are non-renewable, show according to statistic data, and these fossil fuels will be exhausted behind a century; Simultaneously, because of fossil fuel burns in a large number, give off a large amount of carbonic acid gas isothermal chamber gas.Energy dilemma and weather threaten, and force people to seek novel energy energetically.
Biomass granule fuel is a kind of novel energy, is mainly used in gasification and burning.2005, world's biomass solid formed fuel output surpassed 4,200,000 tons.China is as large agricultural country, and biomass resource is abundanter.According to statistics, the annual agricultural crop straw of China is produced 6.04 hundred million tons of total amounts per year, and the quantity of forest product industry wood residue is 4000 ten thousand steres; About 1 ten thousand stere of quantity of the wood residue that paper-making industry produces; The annual production of bagasse is about 4,000 ten thousand tons; The husk amount that Cereals source mill discharges reaches 4,000 ten thousand tons every year.But annual all have a large amount of biomass resources by discarded or rotten voluntarily in vain, and the then direct burning disposal that has has not only caused the waste of resource, has also polluted environment.Therefore, it is imperative to develop this biomass granule fuel.Because the ability that stores in the biomass derives from sun power, therefore, the burning of biomass granule fuel can not pollute environment from cycle perspective.Studies show that the sulphur content and the nitrogen content of biomass granule fuel are low, easily catch fire, the efficiency of combustion height, ash oontent is little, after the burning, SO
2And NO
XAnd the quantity discharged of flue dust is more much smaller than fossil oil, is a kind of clean energy.Its wide material sources, renewable, be subjected to the natural condition restriction few.The Application and Development biomass energy develops social economy to preserving the ecological environment, and implementing the energy sustainable development strategy has major and immediate significance.
Oily sludge is the oil-containing solids refuse that produces in oil production, transportation, refining and oily water treatment process.General oil length is 10～50% in the mud, water ratio is 40～90%, in the China's oil chemistry industry, produce 800,000 t jar bed muds, pond bed mud every year on average, the annual oily sludge that produces of Shengli Oil Field is more than 100,000 tons, annual about 150,000 tons of the oily sludge that produces of Dagang Oilfield, Henan Oil Field is annual to produce 5 * 10
4m
3Oily sludge.Oily sludge is bulky, if do not handled, not only takies a large amount of ploughing, contaminate environment, and cause the waste of resource.Country classifies the oily sludge that industry such as refinery produce as national Hazardous wastes register.
The oily sludge that sewage from oil refinery treatment plant produces, be mainly derived from oil trap bed mud, flotation cell scum silica frost, petroleum tank bed mud etc., be commonly called as " three mud ", these oily sludges are formed different, usually oil length is between 10～50%, water ratio is between 40～90%, simultaneously with a certain amount of solid.
