Description
Technical field
This utility model is related to a kind of selective recovery oil oil extraction plant from oil-containing spent bleaching clay, for Refinery Oil essence
The selectivity removing oil of all kinds of lube base oil spent bleaching clays that process processed produces.
Background technology
In Lubrication oil Production Process, in order to obtain the lubricating oil that colourity is good, transmittance is high, oxidation stability is good, lubrication
Oil, after solvent refining with dewaxing, must carry out post-refining again to remove a small amount of solvent therein and harmful substance (as glue
Matter, sulfur-containing compound, nitrogen-containing compound, organic acid, water isopolarity material), post-refining is last one of lubricating oil processing
Operation.In numerous supplementing refining methods, clay-filtered technical maturity, simple, denitrification percent high desulfurization rate is low, adapts to Chinese crude oil
The feature of low-sulfur high-nitrogen, is widely used in oil plant, the existing 13 sets of clay-filtered process units of China Petroleum Chemicals Corporation's system.
The principle of clay finishing is using the active hargil of high adsorption capacity, lubricating oil to be remained after solvent refining, solvent dewaxing
A small amount of colloid, asphalitine, aphthenic acids, sulfonic acid, acid sludge, basic nitrogen compound, moisture, mechanical admixture, solvent isopolarity material remove
Go.Hargil becomes spent bleaching clay after losing adsorption activity, how in brown to pitchy solid slag, have also coheres in bulk.Refinery utilizes
When hargil carries out refined to oil product, the amount of the hargil that general unit mass oil product need to add is 2 ~ 6%.Although hargil is to polar material
Matter has preferable absorption property, but hargil has certain absorption limit, after polar substancess to be adsorbed reach saturation, that is, loses
Absorbability, now needs to change fresh hargil in time.Consequently, it is possible to refinery produces a large amount of spent bleaching clays every year.Such as, Maoming Petrochemical
Nearly 40 tons of the daily yield of oil plant oil-containing spent bleaching clay.The adsorbed material of oil-containing 30 ~ 40% in spent bleaching clay, have three among these/
Two is preferable oil, and composition is almost consistent with refined oil, in addition about 1/3rd is desirable to remove by the strong adsorptivity of hargil
Undesirable highly polar component, such as colloid, condensed-nuclei aromatics, alkene, colored components etc..
A lot of scholars and technical staff propose oily waste water clay powder recycling oil or regeneration in different documents and patent
The method of hargil.CN 203639441 U discloses the side that a kind of utilization screw extractor reclaims oils and fatss from solid waste oils and fatss
Method, oil recovery solid content is less.Spent bleaching clay is added in solvent naphtha by CN104801266A, at level Four centrifuging process
Reason, the hargil drying after process obtains innoxious hargil.The oil adsorbing in spent bleaching clay can be kept completely separate out, machine after testing
Structure detects, machine oil content is zero to the hargil after treated by the present method, and the machine oil of leaching is recyclable, and hargil is dried can
Raw material as aerated bricks uses.The starting point of above-mentioned technical profession equipment is to make every effort to thoroughly reclaim oil in hargil, or processes
Amount is little, or complex process, is difficult to control to, and technique is nearly all discontinuous, and almost no longer oil-containing but structure are easily destroyed hargil, reclaim
Oil yield is high but difficult quality guarantee.
