Description
Technical field
The invention belongs to environmental protection technical fields, and in particular to a kind of for discarded waste oil mud environment protection treating method.
Background technique
Oil-sludge treatment refers to oil field in process of production, and due to oil extraction, storage collects defeated, processing and crude oil extraction
The sludge generated in liquid treatment process.It is with famous containing certain ingredients in crude oil or crude oil.It is broadly divided into: landing oil
Mud, clear tank greasy filth, flotation dross etc..There is impurity for some, such as crushed stone, broken cement block, broken sand are handled not
There is the solution preferably separated.The waste mineral oil regeneration rate of China is relatively low at present, and a large amount of waste oil is caused to enter not
The business processes of specification cause serious secondary pollution, destroy water resource and are harmful to the human body.And traditional mineral waste
Oily isolation technics need to be handled at 355 DEG C, while be faced with many drawbacks such as highly energy-consuming, maximum discharge, high blowdown.And abandoned mine
Traditional disposal options of object oil have following several: 1. abandon: in early days for a small amount of waste oil, people often pour into it and are lauched
Road, field vacant lot, river, in dustbin.The waste oil being poured into water eventually pollutes rivers.2. burning: generally directly as combustion
Expect, the polycyclic aromatic hydrocarbon oxidation generated in the processing method combustion tail gas containing plurality of heavy metal oxide and incomplete combustion
Object can generate serious pollution to air.3. regeneration: formed from waste mineral oil, go bad object and impurity in waste oil only
Small part, about 1%~25% are accounted for, remaining is all useful component.
Existing Chinese Patent Application No. are as follows: CN201811060224.6 discloses waste mineral oil regeneration technique, the hair
It is bright to be related to waste mineral oil, and in particular to a kind of waste mineral oil regeneration technique.Waste mineral oil regeneration described in the invention
Technique is that waste mineral oil is obtained lube base oil, diesel oil, gasoline and the naphtha of standard through feedstock processing, hydrogenation technique,
The invention is using first to raw material fore-running, then the preprocessing process being evaporated under reduced pressure, obtain preliminary product lube base oil, diesel oil,
Gasoline and naphtha ensure that the cleannes of waste mineral oil.After filtration treatment with mix hydrogen mixing, then carry out hydrotreating.
The invention highway route design is reasonable, and especially after hydrotreating, reaction effluent is carried out hot high score, low point of heat, cold high score, cold low
Point process, sufficiently cleaned up reaction effluent, to obtain the lube base oil of standard, diesel oil, gasoline and stone brain
Oil.But the invention does not propose a kind of for discarded waste oil mud environment protection treating method.
For another example Chinese Patent Application No. is CN201510538279.3, discloses a kind of regeneration treatment system of waste mineral oil
And its technique, which includes: solar heat collector, vacuum treatment installation, centrifuge cycle processing unit, vibration UF membrane dress
It sets, and, collection device；Vacuum treatment installation is connected to solar heat collector；Centrifuge cycle processing unit includes: at vacuum
The centrifuge circulating tank and centrifuge of the outlet of device are managed, the centrifuge circulating tank and centrifuge keep circulation connected state
State；Vibrating membrane separation device includes high frequency diaphragm, vibrates the outlet of membrane separation device and centrifuge circulating tank, passes through height
Frequency vibration film further separates waste mineral oil, and passes through collection device storage treated waste mineral oil.The place that the invention provides
Reason system and treatment process effectively reduce separating treatment temperature, and only generate micro pitch, solve tradition separation skill
The high blowdown problem of the high temperature maximum discharge of art, realizes energy-saving and emission-reduction, and can produce the base oil of high-quality.But the invention
It is a kind of for discarded waste oil mud environment protection treating method also without proposing.
