Description
Technical field
The present invention relates to oilfield chemical fields, more particularly to a kind of polymer-containing oil sludge inorganic agent.
Background technique
Polymer-containing oil sludge, abbreviation greasy filth refer to along with oil, the water, polymerization generated during oil development, production and refinery
Object and silt particle mixture.
Durings the exploitation of petroleum, storage and transportation, refinery etc., inevitably generate containing oil, water, high molecular polymer,
The mixture for being referred to as greasy filth of silt particle particle, direct emission will lead to the serious pollution of soil, earth's surface and underground water, directly or
Harm is generated to plant, animal and human health indirectly.Greasy filth belongs to typical oil exploitation and refining waste, and Yin Qigao contains
Oil, water and silt, direct emission seriously pollute environment, it is necessary to by the processing such as resource utilization, dehydration and drying, solidification, burning
After could qualified discharge.It realizes the sludge dehydrating and drying after resource utilization, is scientific disposal method generally acknowledged both at home and abroad.
Why difficult oil-sludge treatment is, is main cause rich in crude oil and macromolecule polyalcohol.Since each oil field oil-containing is dirty
Composition, property and the sludge treatment technique of mud are different, and the effect of the resource reclaims such as greasy filth hot wash and dehydration and drying processing is natural
Difference is very big.
A large amount of oily (including white oil, diesel oil, crude oil, heavy oil etc.) are usually contained in greasy filth, if it is possible to it separates and utilizes it,
To make it turn waste into wealth.Therefore, carry out the harmless resource utilization containing poly- greasy dirt and handle work, for environmental protection, realize
The clean manufacturing of petroleum industry has a very important significance.
It is major both at home and abroad in order to adapt to the requirement of Law on Environmental Protection Laws & Regulations, reduction greasy filth freight and processing cost
Processing greasy filth new technology is researched and developed one after another in oil company.The technology developed at present has re-injection method, and (injection annular is empty
Between or safe formation), incineration method (kiln process), Thermal desorption method (way of distillation), drilling cuttings cleaning technique, centrifugal separation, solvent
Extraction, biodegradable facture etc..
(1) Thermal desorption method: being exactly to be heated by heating, such as electromagnetic oven, micro-wave oven, steam, conduction oil to material.
It is generally divided into the three phases such as warm-up phase (100 DEG C), middle thermophase (100-300 DEG C), hot stage (300-700 DEG C).Its
Middle warm-up phase mainly carries out moisture evaporative removal to material using waste heat.Middle thermophase primarily with respect to light fraction oil into
Row desorption.Hot stage is pyrolyzed primarily with respect to heavy component.Thermal desorption method advantage is that technique is relatively easy, and equipment is tight
It gathers, skid may be implemented.Disadvantage is exactly that energy consumption is high, has security risk, and tail gas is unable to qualified discharge.
(2) microbiological treatment of greasy filth: being exactly to pass through to extract the simultaneously special bacterium of screening and culturing in oil-containing solids waste,
It is introduced into greasy filth, by 5-7 days even more prolonged biochemical decompositions, so that organic matter degradation is small molecule, carbon dioxide
And water.The disadvantages of this method: first is that specific aim extra-heavy, for different process objects, it is necessary to cultivate different biological bacteriums；Two
When being sapce charge, it is not able to satisfy oil field and produces the needs quickly handled；Third is that some oily waste water are unsuitable for the growth of microorganism admittedly
Breeding；Fourth is that processing is not thorough, usual conversion ratio is up to 80%.
(3) re-injection method: being exactly that a well is opened in pre- subdrilling, well depth is 600-2000 meters general, by water conservancy fracturing technique to choosing
Determine target zone and carry out multiple cracking pressure break, it is buried that greasy filth re-injection is then entered into stratum.Due to not carrying out harmless treatment to greasy filth,
In addition at high cost, so that there is the potential harm to ground water regime and induce the potential risk of geological disaster in the technology.
(4) chemical washing method: exactly greasy filth is washed by the way that the chemical agents such as detergent, remover are added, the party
Method has the characteristics that quick, high-efficient.Currently used detergent has several: first is that oil base cleaning agent, the greasy filth cleaning agent packet
Include laurene, space obstacle agent, lubricant and dispersing agent；Greasy filth cleaning agent is easy to use, and dissolution is efficient, while in the cleaning agent
Main component be hydrocarbon, accounted for 90% of cleaning agent or more, be related to the cleaning of oil storage tank, avoid to oil storage
The pollution of tank guarantees the quality of recycled secondary oil.Second is that aqueous detergent, including single rhamnolipid biological cleaning agent, fat
Alcohol polyoxyethylene ether and bis- (octadecyldimethyl ammonium chloride) the chemical surface activated detergents of trimethylene base.Greasy filth cleaning method:
The cleaning of first time heat chemistry is carried out Step 1: soil cleaning agent is added in greasy filth to be processed, being then allowed to stand makes mixed system point
It is three layers, upper layer is the crude oil washed out, middle layer is water layer, lower layer is Slurry, and Slurry is centrifuged after filtering
Separation, the mud after collecting centrifugation；Step 2: the mud of collection is mixed with clear water, emulsifier is added, it is clear to carry out second of heat chemistry
It washes, is then centrifuged for separating, obtain clean mud.Greasy filth cleaning agent cooperates the method for greasy filth cleaning, secondary using completely new heat chemistry
Cleaning technique scheme, cleaning effect is preferable, oil recovery rate is high, applied widely to different types of oily sludge, improves oil
Mud cleaning efficiency.But the disadvantage is that being easy to cause secondary pollution to water environment.
In conclusion existing frequently-used oil-sludge treatment technology (including above method) generally existing following problems: 1. handling
It is costly；2. generating other secondary pollutions, if incineration method needs burning facility, investment cost is higher, and can release when burning
Poisonous and harmful substance generates secondary pollution；3. oil removal rate is low, differ greatly away from " zero emission standards "；4. process cycle is longer, accounts for
Ground area is big, is unsuitable for live quickly processing, such as microorganism treatment；5. not can be well solved the place of polymer-containing oil sludge
Reason, the accumulation of polymer-containing oil sludge have become the great challenges of puzzlement production.
With the stringent implementation of new environmental regulation, the development trend of oil-sludge treatment is innoxious, recycling, summary, low
Cost.Therefore the high oil-sludge treatment technology of at low cost, simple process, oil removal efficiency is important developing direction.
