Abstract
The present invention relates to a kind of Sludge in Oilfields oxidant, is made up of three kinds of medicaments：Sodium hydroxide, hydrogen peroxide, potassium permanganate, hydrogen peroxide react under sodium hydroxide and potassium permanganate catalytic action, produce hydroxyl radical free radical；Oily sludge oxidant is by medicament A：The sodium hydroxide of technical grade 99%, medicament B：The hydrogen peroxide of technical grade 35%, medicament C：18000ppm potassium permanganate, three parts composition, wherein the quality proportioning of above-mentioned three kinds of medicaments is 10:200:1.Still contain the oily sludge of higher oil content after being handled with such a oxidant and method for oxidation for recycling minimizing, the oxidation operation that can decompose hardly possible avoids harm of the oily sludge to surrounding environment into carbon dioxide, water and inorganic salts；This oxidant has wider adaptation unit for oily sludge moisture content and oil content, moisture content 40% 60%, and oil content 5% 10%, dosing also can adjust preferred；This oxidant can be such that oily sludge is contacted with medicament evenly in presence of water, and reaction is more complete.
Description
Technical field
The present invention relates to a kind of Sludge in Oilfields oxidant, belong to oxidant technical field.
Background technology
The oil exploitation cause in China, just in fast development, still, while being continuously increased with exploitation amount, also bring
The remaining oily sludge to be spun off after exploitation from crude oil, the generation of oily sludge mainly include oil extraction, accumulating with
And three mud of oil plant etc..This oily sludge by techniques such as quenched centrifugations after most of crude oil is reclaimed, after centrifuge processing
The crude oil of oily sludge still oil-containing 10% or so, 2% standard is not reached, this part crude oil is difficult to be separated from oily sludge
Out resource recycling value is little, but serious destruction and pollution can be caused to surrounding environment again by discharging, therefore with containing
Such a sludge is carried out oxidation Decomposition into carbon dioxide, water and inorganic salts by greasy dirt oxidant.Some domestic and international knowledgeable people,
Have attempted to decompose low concentration oily sludge with the method for chemical oxidation, but success engineer applied has no report.
The content of the invention
The technical problem to be solved in the present invention, be to provide a kind of oily sludge oxidant, can will through pretreatment it is quenched from
Crude oil of the oil content in the sludge of 10% or so oil content carries out oxidation Decomposition into nontoxic carbon dioxide, water, inorganic after the heart
Salt, so as to reach oil content be less than 2% standard, even up to 1%, so as to reach the environmentally safe mesh of clean and effective
's.
To achieve these goals, technical scheme is as follows.
A kind of Sludge in Oilfields oxidant, it is made up of three kinds of medicaments：Sodium hydroxide, hydrogen peroxide, potassium permanganate, peroxide
Change hydrogen to react under sodium hydroxide and potassium permanganate catalytic action, produce hydroxyl radical free radical；Oily sludge oxidant is by medicament A：
The sodium hydroxide of technical grade 99%, medicament B：The hydrogen peroxide of technical grade 35%, medicament C：18000ppm potassium permanganate, three parts group
Into wherein the quality proportioning of above-mentioned three kinds of medicaments is 10:200:1.
Above-mentioned oxidant application method is as follows：Medicament A is used when handling oily sludge, water is then added and stirs 20min,
Oily sludge is well mixed and is fluidized, then add medicament B and C mixed solutions, continue to stir 20min, carry out centrifugal dehydration,
Oil content is down to 1%.
Reaction principle：Hydrogen peroxide is a kind of oxidant of green non-pollution, and hydrogen peroxide is in sodium hydroxide and permanganic acid
Substantial amounts of hydroxyl radical free radical can be quickly produced under potassium catalytic action, hydroxyl radical free radical has extremely strong oxidability, same to contain greasy dirt
Organic compound reaction in mud, macromolecular biodegradable organic compoundses are oxidized to the carbon dioxide of small molecule, water and inorganic
Salt.
The beneficial effect of the invention is：After being handled with such a oxidant and method for oxidation for recycling minimizing still
Oily sludge containing higher oil content, the oxidation operation that can decompose hardly possible are avoided and contained into carbon dioxide, water and inorganic salts
Harm of the greasy dirt to surrounding environment；This oxidant has wider adaptation unit for oily sludge moisture content and oil content, contains
Water rate 40%-60%, oil content 5%-10%, dosing also can adjust preferred；This oxidant can make to contain in presence of water
Greasy dirt contacts evenly with medicament, and reaction is more complete.
Embodiment
The embodiment of the present invention is described with reference to embodiment, to be better understood from the present invention.
Embodiment
Sludge in Oilfields oxidant in the present invention, it is made up of three kinds of medicaments：Sodium hydroxide, hydrogen peroxide, permanganic acid
Potassium, hydrogen peroxide react under sodium hydroxide and potassium permanganate catalytic action, produce hydroxyl radical free radical；Oily sludge oxidant by
Medicament A：The sodium hydroxide of technical grade 99%, medicament B：The hydrogen peroxide of technical grade 35%, medicament C：18000ppm potassium permanganate, three
It is grouped into.
Above-mentioned oxidant application method is as follows：Medicament A is used when handling oily sludge, water is then added and stirs 20min,
Oily sludge is well mixed and is fluidized, then add medicament B and C mixed solutions, continue to stir 20min, carry out centrifugal dehydration,
Oil content is down to 1%.
Centrifuge mud extraction after the quenched centrifugal treating in certain domestic oil field, moisture content 50%, oil content 8%, takes 1kg oily sludges
In with stirring container, add 10g medicament A, add 200ml running water, be stirred, when sludge mixed with medicament
Even, then adding 200ml medicaments B, (medicament B and medicament C volume ratio is 200 with C mixed solutions:1), continue to stir 60min,
Carry out centrifugal dehydration, oil content 0.8%.
Certain domestic Oil Field application apparatus coordinates oxidating chemicals, centrifuge mud extraction after processing, moisture content 50%, oil content
8%, oil content 0.8% after processing, moisture content 50%.
Described above is the preferred embodiment of the present invention, it is noted that for those skilled in the art
For, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications are also considered as
Protection scope of the present invention.
