Description
Technical field
The present invention relates to a kind of is the method for raw material production haydite with oil sludge and sand; described method is that de-oiling sand mud (or add auxiliary material such as clay in de-oiling sand mud make compound pottery mud) is carried out granulated processed; make particulate state haydite blank, through high temperature sintering process for producing ceramic product.
Background technology
Oil sludge and sand also is oily sludge, produces in the oil production activity, is mainly derived from each link of Oil extraction, transportation and treating processes, by crude oil and other Organic pollutants oil, silt particle, the mixture of water.General oil length is 10-50% in the mud, and water ratio in the China's oil chemistry industry, produces 800,000 tons of oil sludge and sand 25-50% every year on average; Shengli Oil Field produces oil sludge and sand more than 100,000 tons every year, the about 50,000 tons of oil sludge and sand of the annual generation of Henan Oil Field.Contain cacodorous toxic substances such as a large amount of benzene series things, phenols, anthracene, pyrene in the oil sludge and sand, if do not handled, contaminate environment not only, and cause the waste of resource.Because the oil sludge and sand solid load is low, the water ratio height presents the suspended dispersed state again, thereby bulky, the different oil sludge and sand of originating simultaneously is as fresh and aged oil sludge and sand, it is formed and physical properties all may have than big difference, as viscosity, water ratio, dehydration property, oily water separation etc.; The complicated component of oil sludge and sand own contains a large amount of aging crude oil, cured matter, bituminous matter, colloid and suspended solid, bacterium, salt, sour gas, corrosion product and a small amount of mechanical impurity etc.About 25-50% is water in the oil sludge and sand, 5% inorganic sediment such as silt particle, and about 70% is hydrocarbon polymer, and wherein, bituminous matter accounts for 7.8%, and paraffin accounts for 6%, mud ash oontent 4.8%.At these different character, adopted different method for innocent treatment, as landfill method, re-injection method, drying bed facture, burning method, carbonizing treatment method, biological treatment etc., aforesaid method or exist harmless treatment thoroughly not pollute environmental problem or exist oil contained in the oil sludge and sand, silt particle can not recycle and waste resource also takies a large amount of soils and carries out problems such as landfill.The annual oil sludge and sand that produces in oil field, unprocessed, pay effluent charge and reach more than one hundred million units, also need to bear a large amount of expenses such as permanent fees paid for taking rural land, well site maintenance cost, administrative fine simultaneously.
Chinese patent 200410082899.2 has been announced a kind of treatment process of oil sludge and sand, adopt the method for oil, water, silt particle solid-liquid separation, be the oil sludge and sand → homogenize → chemical separation of the heating → separation → mechanical dehydration of heating → curing → microbiological treatment → mummification landfill, separating of oilly come out to recycle contained in the oil sludge and sand.But the silt particle that adopts this method to separate generally all adopt landfill after the burning disposal or directly landfill reach the purpose of oil sludge and sand harmless treatment, promptly spent processing costs and wasted sediment resource again, also taken a large amount of soils simultaneously.
