Abstract
A decomposition method of effluent oil sludge is characterized in that the effluent oil sludge is added into a treatment tank which can be heated up, according to the weight percentage in the effluent oil sludge, sodium metasilicate, polyether polylol and ethylene diamine tetraacetic acid are added to mixed evenly with the effluent oil sludge, and is reacted to the effluent oil sludge under the condition of being heated up, thereby ensuring that oil, mud and water are separated completely, oil at the upper layer is extracted, and the treatment without social effects of pollution is performed for the rest mud and water. The sodium metasilicate, the polyether polylol and the ethylene diamine tetraacetic acid which are added according to the weight percentage in the effluent oil sludge are respectively 2.5 to 3.0 percent, 0.3 to 0.5 percent, and 0.05 percent. The sodium metasilicate, the polyether polylol and the ethylene diamine tetraacetic acid react to the effluent oil sludge under the condition of being heated up to 70 to 85 Deg C. The three articles are innoxious and are all neutral materials, no secondary pollution is caused, a little dosage is needed, and the decomposition of effluent oil sludge is complete. The invention has the advantages of wide raw material sources, lower price, simple technique and easy operation.
Description
Technical field
The present invention relates to the oil-bearing sludge decomposition method that produces in the oil recovery process of oil field.
Background technology
Sump oil mud is in oil field oil recovery or the oil refining process, the thick viscid oil contaminants that contains that spins off from oil.Present treatment process: partition method, decomposition method, re-injection method are arranged, bury method, biological degradation method or burning method to sump oil mud.These treatment processs except that burning method, maximum shortcoming are to exist processing not thorough, need take the farmland of a large amount of preciousnesses, and chemical separation, decomposition agent in separation, the decomposition method can cause secondary pollution.Though burning method is comparatively thorough, burn for the sump oil mud of oil-containing more than 35%, do not meet energy-conservation principle.The common oil-containing 35% of the sump oil mud that produces after the oil production, this part sump oil mud is valuable secondary resource, if these sump oil mud are carried out the collection of science, and develop this partly crude oil, not only reclaimed a large amount of resources, bring huge economic benefit, and the meeting pollution abatement, huge environmental benefit produced.
Summary of the invention
The technical problem to be solved in the present invention provides and extracts crude oil a kind of sump oil mud can the decomposition, and cost is low, and disaggregating treatment is oil-bearing sludge decomposition method completely.
The technical scheme that adopts is:
A kind of oil-bearing sludge decomposition method, sump oil mud is added in the treatment trough that can heat, stir by per-cent adding Starso, polyether glycol and the disodium salt and the sump oil mud that account for sump oil mud weight, under heating condition, react with sump oil mud, oil, mud, water are thoroughly separated, extract upper strata oil composition, all the other mud, water are done nuisanceless processing.
The above-mentioned Starso that adds by sump oil mud weight percent is that 2.5-3.0%, polyether glycol are that 0.3-0.5%, disodium salt are 0.05%.
Above-mentioned Starso, polyether glycol and disodium salt and sump oil mud react being warmed under the 70-85 ℃ of condition.
The present invention handles that sump oil mud method is simple, science, rationally.Adopt Starso (Na
2SiO
3) modulus is 1 neutral crystal type water glass, nontoxic polyether glycol, disodium salt (C
10H
16N
2O
8) complexing agent adds sump oil mud and be dissolved in the sump oil mud, Starso reduces sump oil mud surface tension, improves the decomposition effect of sump oil mud.Described polyether glycol can be used as crude oil demulsifier in the present invention, can interrupt the effect of crude oil molecular chain, prevents that hard scale from forming, and promotes the abundant breakdown of emulsion of sump oil mud, reduces its surface tension, improves sump oil mud and decomposes effect, favourable secondary oil recovery.Described disodium salt is in the present invention as complexing agent, generate water-fast intermediate product, the nuclear that coagulates as new life, promote suspended particulate matter or colloid thing that the sedimentation downwards of cohesion back takes place, reduce the organic content in the pending water, thereby improved decomposing, purifying effect effectively sump oil mud.The above-mentioned nontoxic neutral material that is of three kinds of chemical substances can not produce secondary pollution, and it is thorough that consumption decomposes sump oil mud less.Have raw material sources extensively, price is lower, technology is simple, the advantage of easy handling.
Embodiment
Embodiment one
A kind of oil-bearing sludge decomposition method, sump oil mud is added in the groove of handling of can heating, Starso by the per-cent adding 2.8% that accounts for sump oil mud weight, the polyether glycol of adding 0.4%, the disodium salt of adding 0.05%, and stir with sump oil mud, be warmed to 80 ℃ with the greasy dirt reaction, make oil, mud, water sepn.
Embodiment two
A kind of oil-bearing sludge decomposition method, sump oil mud is added in the groove of handling of can heating, sump oil mud is warmed to 75 ℃, Starso by the per-cent adding 2.6% that accounts for sump oil mud weight, the polyether glycol of adding 0.3%, add 0.05% disodium salt, and stir with sump oil mud and to make oil, mud, water sepn.
Embodiment three
A kind of oil-bearing sludge decomposition method, by weight per-cent in the sump oil mud added 3.0% Starso, the polyether glycol of adding 0.5%, the disodium salt of adding 0.05%, mix, mixed sump oil mud is put into and can be warmed to 78 ℃ and greasy dirt reaction at the treatment trough of heating, make oil, mud, water sepn.
