Abstract
The invention relates to the technical field of chemical product separation, in particular to an oily sludge decomposition treatment method. According to the decomposition treatment method, oil sludge is added to a stirring tank firstly, clear water is added, and the mixture is preheated to 70-100 DEG C, stirred at the temperature of 45-75 DEG C and subjected to thermal insulation for 20-60 minutes until the oil sludge is sufficiently emulsified and dispersed to form an emulsion taking water as a dispersion phase; a separating agent and oil sludge are added and uniformly stirred, the PH value of the oil sludge is adjusted to the acidity value, and the separating agent and the oil sludge react under the heating condition, so that oil, sludge and water are thoroughly separated, petroleum oil ingredients on the upper layer are extracted, and the rest sludge and water are subjected to pollution-free treatment. According to the oily sludge decomposition treatment method, the treatment energy consumption and the cost are low, and environmental pollution can be reduced.
Description
Technical field
The present invention relates to the technical field that a kind of Chemicals are separated, specifically a kind of oily sludge decomposing process.
Background technology
Along with crude oil production, a large amount of oil-containing mud sand is carried out oil reservoir, is deposited on the various container tank bottom of pumping plant.These oil sludge and sand can not directly utilize or arrange outward, are stacked air-dry or bury underground, both contaminate environment, waste resource again usually used as waste, bring huge financial loss to enterprise simultaneously.At present normally by greasy filth, heat treated is carried out to the treatment process of oil sludge, and then add separating agent, settlement separate, obtain oil, effluent sewerage and mud.But the separating agent used is generally the tensio-active agent of nonionic, positively charged ion, negatively charged ion or its mixture, these separating agents are excessive adds the pollution that membership causes water body.
Summary of the invention
The object of this invention is to provide a kind of process energy consumption low, cost is low, reduces the oily sludge decomposing process of environmental pollution.
The present invention solves the scheme that its technical problem takes: a kind of oily sludge decomposing process, first in stirred pot, add oil sludge, add clear water and be preheating to 70-100 DEG C, insulation 20-60 minute is stirred, until becoming fully emulsified for oil sludge dispersion with water is the milk sap of disperse phase under 45-75 DEG C of temperature condition; Add separating agent again and oil sludge stirs, regulate its pH value to acid, react in a heated condition, oil, mud, water are thoroughly separated with greasy dirt, extraction upper strata oil composition, all the other mud, water make nuisanceless disposal.
Say further, described separating agent is the wherein a kind of of sulfuric acid, sulfonic acid or nitric acid.
Advantage of the present invention is that cost is low, and process energy consumption is low, greatly reduces the pollution to environment.
Embodiment
The present invention is further described with the following Examples,
Embodiment, a kind of oily sludge decomposing process, is characterized in that, first in stirred pot, add oil sludge, add clear water and be preheating to 70-100 DEG C, under 45-75 DEG C of temperature condition, stir insulation 20-60 minute, until becoming fully emulsified for oil sludge dispersion with water is the milk sap of disperse phase; Add separating agent again and oil sludge stirs, regulate its pH value to acid, react in a heated condition, oil, mud, water are thoroughly separated with greasy dirt, extraction upper strata oil composition, all the other mud, water make nuisanceless disposal.Described separating agent is the wherein a kind of of sulfuric acid, sulfonic acid or nitric acid.
Should be understood that this embodiment is only not used in for illustration of the present invention to limit the scope of the invention.In addition, should be understood that those skilled in the art can make various changes or modifications the present invention, and these equivalent form of values fall within the protection domain that the application's appended claims limits equally after having read the content that the present invention lectures.
Claims (2)
