Description
Technical field
The present invention relates to the dry vapo(u)rization system of a kind of board-like process oily sludge, the invention still further relates to a kind of technique adopting said system process oily sludge.
Background technology
Oily sludge refers to that crude oil or processed oil are mixed into earth or other media, and oil content wherein directly can not reclaim and may cause the mixture of the variform of environmental pollution.Oily sludge by sources can be divided into three kinds dissimilar:
(1) drilling sludge
Drilling sludge is mainly derived from the Discarded Drilling Materials well finishing liquid in drilling completion operation process, landwaste, a small amount of waste lubrication oil that drilling outfit runs, maintenance produces and the mixture of operation wastewater and earth's surface, well site earth sand grains.Drilling sludge oleaginousness compared with low, viscosity is large, particle is thin, dehydration is difficult, intractability is large, has a strong impact on ecotope.
(2) oil extraction in oil field, collect defeated process produce oily sludge
The oily sludge produced in oil extraction in oil field process is mainly from pilot production open flow, acidifying, pressure break, remedial operation, conduit wiring piercing and the ground crude oil produced and oily sludge.The oil that gathering system oily sludge is mainly derived from block station, the oil tank of joint station, slurry tank, Water Tank, oil trap, lighter hydrocarbons source mill, purifying device for natural gas clear out is husky, greasy filth, oil product storage tank is when storing oil product, a small amount of mechanical impurity in oil product, the grains of sand, earth, heavy metal salt and the heavy oil such as paraffin and bituminous matter component deposition, at tank bottom, form tank bottom oil sludge.The oil length of this kind of mud is between 10 ~ 40%, and water ratio is between 40% ~ 90%.
(3) refinery oily sludge
The oily sludge of refinery is mainly derived from sewage works oil trap bed mud, flotation cell scum silica frost, petroleum tank bed mud etc., is commonly called as " three mud ".These oily sludges composition is different, usual oil length between 10% ~ 50%, water ratio between 40% ~ 90%, simultaneously with a certain amount of solid.
In China's oil, petrochemical industry, the various oily sludges such as the drilling sludge produced every year on average, tank bed mud, pond bed mud reach ton up to a million.According to " National Hazard refuse register " (numbering HW08) regulation, Sludge in Oilfields belongs to the scope of Hazardous Wastes Management." national promotion law on cleaner production " requirement must carry out harmless treatment to oily sludge.The pollutant abatement technology of oily sludge causes the attention of leaders day by day.Therefore; from environment protection and the recovery energy; and the angle of cleaner production is set out; strengthen the dynamics of process oily sludge; find a kind of process of cost-effective applicable Sludge in Oilfields and utilize technology; carry out oily sludge harmless treatment very necessary, recycling sludge utilizes the fundamental way that will be ultimate disposal from now on.
2, process for treating oil-containing sludge
The method of current domestic general process oily sludge has: burning method, biological treatment, natural mummification method, chemico-heating wash method etc.
Burning method is through the concentrated pretreated oily sludge of dehydration in advance, and deliver to incinerator and burn, temperature 800 ~ 850 DEG C, burning through 30min can be complete, and the lime-ash after burning needs process further.Burning disposal method advantage is mud after burning, and multiple nuisance almost all removes, and decreases the harm to environment, it is effective that refuse subtracts appearance, processes safer, and shortcoming is that power consumption is large, create secondary pollution in burning process, oily resource is not recycled utilization, wastes valuable resource; Oily sludge need be carried out biological degradation by biological treatment, lasts longer, and same oily resource is not recycled utilization; Nature mummification method relies on dehydration by evaporation, and floor space is large, easily produces secondary pollution.The crude oil recovery process application of the ground crude oil that chemico-heating wash is higher to oleaginousness, emulsification is lighter and oil-sand is more.Sludge residue water content after separation is greater than 90% and containing a large amount of chemical agents, palpus thickening process further, processing cost is higher, and level of automation is low, and technical process is tediously long, complicated, and mechanical fault hidden danger is more.
Although the method for visible process is a lot, all due to reasons such as poisonous harmful substance contents residual after investment, process exceed standard and running cost is high, the never sizable application at home of disposal of oily sludge problem.
