It is demulsified the present invention relates to greasy filth and disperses press filtration medicament and preparation method and oil-sludge treatment method.Demulsification dispersion press filtration medicament includes liquid phase：30 40 parts of water, 50 60 parts of composite demulsifying agent, 10 20 parts of fire retardant；Solid phase：0.5 1 parts of sodium hydroxide, 0.5 1 parts of sodium bicarbonate, 0.5 1 parts of polyacrylamide, 5 10 parts of sulfur elimination.The medicament mainly uses inorganic matter and small organic molecule comprehensive function, oil, water, solid three phase separation are realized into the defeated batch processing job greasy filth demulsification dispersion of high sulfur Gas Fields collection, enter water phase after the sedimentation of solid phase natural flocculation, oil phase saponification, press filtration natural subsidence solid phase solves the problems, such as that batch processing greasy filth cannot normal press filtration.
Description
Technical field
The invention belongs to the treatment technologies of greasy filth, are related to a kind of greasy filth demulsification dispersion press filtration medicament and preparation method and greasy filth
Processing method, in particular for high sulfur Gas Fields gathering line inner wall using diesel oil and corrosion inhibiter film operation when generate contain
Sulphur greasy filth (i.e. batch processing greasy filth) realizes the demulsification dispersion press filtration medicament that grease is consolidated three phase separation and provided.
Background technology
High sulfur Gas Fields include pitch class, crude oil class object in gathering line operation process, from complex formation organic matter
The substances such as matter, the water flooding of high-sulfur compound, all types of corrosion inhibiter added during batch processing job, pipeline deposit, pass through
After physics and chemical reaction, depth emulsification, mixing, aging eventually form a kind of paste greasy filth.These greasy filth in pipeline, no
It is merely blocked by, corroded pipeline, and the greasy filth after collecting is in press filtration processing procedure, blocks folded spiral shell filter press and plate and frame filter press
Filter cloth, and paste greasy filth moisture content does not have any effect after press filtration.A large amount of high sulfur-bearing greasy filth closed can only store, and cannot
Direct press filtration brings great security risk and hidden danger to the production of high sulfur Gas Fields.
At present, the domestic mode about the batch processing oil-sludge treatment of high sulfur-bearing mainly has following four：
First, burning, coking mode, this processing mode is in the current high sulfur-bearing batch processing oil-sludge treatment of puguang gas field
It has been used.
Second is that elution curing process mode, document《Sludge in Oilfields crude oil elutes and curing research》, 2012, Shandong is big
Master's thesis is learned, the micro- demulsifier formed using kerosene, dodecyl sodium sulfate, n-amyl alcohol is disclosed and elutes greasy filth, reuse
The method that portland cement handles greasy filth for curing agent.
Third, extraction and hot wash mode, greasy filth is handled, and recycle oily substance using extractant and surfactant.It is hot clear
Temperature control is washed at 80 DEG C, liquid-solid ratio is controlled 8:1, extractant mainly includes N-Methyl pyrrolidone-carbon disulfide, tetrahydrochysene furan
It mutters, ethyl alcohol, petroleum ether etc., surfactant is mainly using lauryl sodium sulfate, alkyl phenol polyoxyethylene ether etc..
Fourth, centrifugal dehydration mode, minimizing greasy filth, this includes the use of cyclone separator and centrifuge, is dehydrated greasy filth,
Minimizing greasy filth.
More than four treatment measures there are following major defects：
First, using burning, coking, for the greasy filth that high sulfur Gas Fields gathering line batch processing job generates, energy consumption is big,
And the oxide that sulfide is combusted into is toxic, and pollutes air.
Second is that the mode that extraction heating is washed, the depth emulsification generated for high sulfur Gas Fields gathering line batch processing job,
The greasy filth of aging can not achieve complete demulsification, and produce large volume of oil phase, to the greasy filth of the high sulfur-bearing of enclosed workshop
Processing water phase brings difficulty in next step, and treated sludge can not use filter press to carry out press filtration.
Third, centrifugal dehydration mode and elution curing mode, oil removing demulsification is poor, and is unfavorable for gas field sludge and subtracts
Quantization requirement, is not suitable for the in-situ processing of high sulfur Gas Fields batch processing greasy filth.
The patent of Publication No. CN107216008A discloses a kind of formula and preparation method of oily sludge demulsifier, should
Patent is provided to be used by each component weight ratio：11%-20%A citric acids, 3.5%-10% emulsifiers, 25%-35% infiltrations
Agent, 6.5%-15% tetrasodium ethylenediamine tetraacetates, 1.5%-5% inorganic salts, 5%-8% sodium metasilicate, 0.5%-5% alkali and water
Demulsifier is prepared, processing greasy filth improves the utilization ratio of petroleum hydrocarbon.
The Chinese patent of Publication No. CN107253813A discloses the recovery and treatment method of greasy filth, this method by greasy filth,
Water, extractant are according to mass ratio 1:2：The mixed ratio of 0.3-0.7 so that greasy filth de-oiling, wherein extractant are organic solvent, dispersion
Agent, anion surfactant are according to mass ratio 1:0.3-0.5-0.5-0.8 is compounded, and main processing intent is recycling profit
With the oily substance of extraction.
More than two patents essentially consist in recycle extraction oily substance, for processing post-process after greasy filth such as
What minimizing and how the demulsification dispersion press filtration of the high sulfur-bearing greasy filth higher to emulsification, degree of aging does not provide technology
Enlightenment.
Invention content
Present invention seek to address that the high sulfur-bearing greasy filth that high sulfur Gas Fields gathering line batch processing job generates can not be deposited directly
