Description
Technical field
The present invention relates to a kind of oily sludge thermal oxide skid processing unit, the block that is particularly suitable for use in is scattered, ground environment
The oilfield environment of condition difference.
Background technology
With continuing to develop for petroleum industry, all kinds of oily sludges such as abandoned oil produced in Petroleum Production, refining process
Oily sludge, oily sludge of oil accident generation that base mud, big tank settled sludge, sewage disposal process are produced etc.
Increase therewith.Different type sludge quality is complicated, oil content difference is big, intractability is big, processing cost is high, if it is untreated just
Ground is filled or stacked, the not only limited petroleum resources of significant wastage, and to surrounding enviroment can cause severe contamination.At present,
The research department such as domestic each main Petroleum Production and petrochemical enterprise, universities and colleges strengthens discarded slurry, oily sludge
Processing Technology Research and application, have developed a variety of discarded slurries, process for treating oil-containing sludge and technique, but because of processing cost
The factors such as height, process conditions harshness are limited, and the practical application in industry of achievement in research is few.
Under this background, seek that more rational discarded slurry and oily sludge be innoxious, resource treatment technique, no
Only it is related to the production in oil field itself, the improvement of living environment and the raising of economic benefit, in environmental protection and will also carries
Doulbe-sides' victory is realized in high corporate image, there is far-reaching realistic meaning and great environmental benefit, economy to the sustainable development in oil field
Benefit and social benefit.
Oily sludge concentration technique is to make liquid in sludge using related agents, be partially separated admittedly, realizes that sludge volume subtracts
Less, the purpose that processing procedure simplifies.The purpose of sludge condensation is to remove free water, to reduce sludge volume.Usual sludge condensation
By free settling, flocculating setting, stratification sedimentation and 4 stages of Compression Settlement, moisture content is by original after oily sludge concentration
99% is down to 90% or so, 1/10th of volume equivalent to original volume.
Oily sludge Landfill be exactly select on land suitable natural place or it is artificial reconstructed go out suitable place,
The method for being covered oily sludge with soil layer, it is that processing method grows up one is stacked and backfilled from solid waste
Item technology, its advantage is that handling process is simple, cost is low, capacity is big, instant effect, can be effectively isolated pollutant, and can be right
Oily sludge after landfill is effectively managed.But it is there is also some problems, such as suitable place should not be found, sludge transport
Higher, the landfill yard finite capacity with landfill place construction cost, takes substantial amounts of soil, and crude oil in the sludge after burying and
Can not be decomposed in the chemical agent short time, the seepage of harmful components may be polluted to underground water, landfill yard it is hygienic, smelly
Gas problem causes secondary pollution etc..Therefore, this kind of method processing oily sludge proportion is less and less.
Oily sludge burn be using sludge organic principle it is higher, with certain calorific value the features such as come disposing sludge.Should
It is a technical advantage that the completeness of its processing, reduction rate can reach 95% or so, its organic matter is fully oxidized, and heavy metal (is removed
Outside mercury) almost it is trapped within entirely in lime-ash.But burning there are problems that following always：(1) investment and operating cost are higher；
(2) implementing plan is more difficult；(3) flying dust, clinker and flue gas are produced in burning process.Research discovery, in incineration residue, especially
It is to contain more Cd, Pb and other heavy metals in flying dust (its poisonous, organic pollution is higher by the several orders of magnitude of lime-ash), is belonged to
Danger wastes, if dealing with improperly, easy seepage and polluted underground water body, neighbouring surface water body and soil, and then endanger the mankind
Health.Containing extremely toxic substances such as dioxin and furans in the flue gas of discharge, if control is improper may to produce secondary pollution.Example
Chuan Bianding such as Japan Kagoshima county is not thorough due to burning, and makes soil property severe exacerbation around, the bioxin soil being stripped out
65,000,000 t are accumulated in storehouse in position；(4) useful component in sludge is not fully utilized.
Oily sludge curing process is to solidify oily sludge by physico-chemical process or be included in inertia curing substrate
In a kind of innocent treatment procedure, to transport, using or disposal.This processing method can be reduced largely containing greasy dirt
The erosion and leaching of harmful ion and organic matter to soil in mud, so as to mitigate the influence and harm to environment.Due to this side
Method is a kind of method for being more easy to be received by environment of substitution backfill, therefore receives attention in recent years.Change used in solidification
Learn agent and be divided into organic curing agent and the major class of inorganic solidification agent two, organic curing agent includes Lauxite, polyester, oxirane, third
Acrylamide gelinite, polybutadiene etc., inorganic solidification agent have Bo Telan cement and the ardealite developed in recent years etc..
At present, the country still rests on conceptual phase for oily sludge curing process, and the scheme used at present is in oil recovery
Crosslinking agent, reinforcing agent and curing agent are added in the oily sludge that factory's sewage disposal is produced curing process is carried out to it, experiment is obtained
Good solidification effect.Curing process has strict demand to the oil content in sludge, salt content etc., and oil content, salt content are high
Solidification intensity is then greatly lowered.
Oily sludge thermal desorption or heat treatment technics be the beginning of the nineties in last century foreign countries develop rapidly, extensively use
It is a kind of sludge high temperature handling process of remodeling in the means of oily sludge harmless treatment.Can measure needed for pyrolytic reaction
Certainly in the generation ratio of various products, and generate more relevant than the granularity of speed, temperature and raw material with heating.
At present, external refinery develops many kinds of thermal desorption techniques.Mainly have comprising low temperature (107-204 DEG C)-high temperature
The Oil Containing Sludge Treatment of (357-510 DEG C) heating evaporation-condensing steps, also dries oil-containing using boiler emission hot waste gas
Patented technology of mud cake etc..The thermal desorption processing method of oily sludge can reclaim hydro carbons, but the reaction of the technique typically exists
Carried out under high temperature, reaction condition requires higher, and operation is more complicated, needs to be further improved.
Oily sludge pyrogenic process processing oily sludge is substantially exactly the depth heat treatment to mink cell focus, and its reaction is hydrocarbon
The thermal conversion processes of matter.It is dirty that many refinery's 1990s just handle API oil interceptors using Mobil greasy filth coking process
Mud.Zhao Dongfeng et al. proposes following technological process and reaction condition：Raw material (greasy filth, oil-sand) removes larger after pretreatment
Mechanical admixture, sends into the pyrogenetic reaction kettle (180 DEG C) having been warmed up after being admixed using transmission equipment and disposable catalyst.Close kettle
Heating carries out catalytic cleanerr reaction afterwards, and reaction temperature is controlled at 490 DEG C, and the reaction time is 60min.Pyrogenetic reaction gas passes through heat tracing
