Abstract
Present invention process, heat treatment is combined with propane extraction：Heat treatment has destroyed the additive in waste lubricating oil, drastically increases the effect of propane extraction；Propane extraction is precipitated out well the additive being deteriorated in used oil, mechanical admixture and rotten component again.Heat treatment is combined with propane extraction, can efficiently be handled useless lubrication, is that existing waste lubricant oil regeneration technology is significantly improved.
Description
Technical field
The present invention relates to a kind of process for regeneration of waste lubricating oil.This method belongs to petrochemical industry and environmental protection technical field.
Background technology
Waste lubricating oil belongs to hazardous waste, containing a large amount of carcinogens, and topple over to cause to seriously endanger to natural environment, combustion
Burning can produce the harmful substances such as a large amount of dioxin, sulphur phosphorus organic compound.In waste lubricating oil only have some hydrocarbon (about 10%~
25%) go bad, remaining most of hydro carbons composition is still the main viscosity carrier of lubricating oil, is removed after rotten thing and impurity, you can again
The lube base oil conformed to quality requirements is generated, and regeneration rate can reach 70% or so.2012, China's lubricating oil is actual to disappear
The amount of expense is calculated, every year at least recyclable 4,700,000 tons of waste lubricating oil up to 8,500,000 tons according to 20% proportion of goods damageds and 70% rate of recovery,
Renewable more than 330 ten thousand tons of lube base oil.
The waste lubricant oil regeneration industry of China starts development the sixties in last century, but backward in technique, with low quality.Previous generation
Record the later stage eighties, since waste lubricant oil regeneration industry starts fast development, particularly 2000 year, waste lubricant oil regeneration enterprise rule
Mould has very big lifting, still, however it remains the problems such as manufacturing process is simple, pollution environment is serious.In consideration of it, national development and changing
The leather committee have issued《Implement on printing and distributing " 12 " comprehensive utilization of resources instruction and the comprehensive utilization of large solid waste
The notice of scheme》, notification waste lubricating oil was reclaimed and recycling is the key industry for encouraging development, from 2013 11
Month on October 31st, 1 day 1, to lube base oil, gasoline, diesel oil for being produced by raw material of the waste lubricating oil of recovery etc.
Industrial oil exempt from consumption tax.Waste lubricant oil regeneration enterprise development is supported by preferential tax revenue, can both alleviate China's oil money
Source pressure in short supply, can help regular distributors to spend hard time again, promote the sector industrialized development, improve the row
The technical merit of industry, reduction environmental pollution.
The engineering technology difficult point of waste lubricant oil regeneration is mainly reflected in：A. modern lube oil additive species is various, develop
Quickly, the regeneration to waste lubricating oil brings extreme difficulties；B. in regenerative process, rotten component and additive meeting in waste lubricating oil
It is pyrolyzed coking, blocking pipeline and equipment.
The content of the invention
The purpose of the present invention is the additive destroyed using high-temperature heat treatment in waste lubricating oil, is then extracted again by propane
Remove sediment.
Technical solution of the present invention：Used oil first 120 DEG C ~ 200 DEG C carry out distillation dehydrations, be then heated to 260 DEG C ~
350 DEG C, stopped into heat treatment tower and destroy within 0.5 hour ~ 4 hours most additives therein, then it is cold with raw material heat exchange
But to after 240 DEG C or so, carrying out distillation removing Light ends, then with propane propane extraction tower is entered simultaneously.Change in waste lubricating oil
Matter component, mechanical admixture and the additive being deteriorated are discharged from extraction tower bottom, and preferable component is dissolved in propane from extraction tower
Flow out at top.
Advantages of the present invention：
Firstth, heat treatment and propane extraction has application in waste lubricant oil regeneration production, but has no and be combined therebetween；
Second, existing Technology for Heating Processing would generally subsequently carry out filtering and removing bits, and still, this bits are very sticky, i.e.,
It is to use special filtering material and method, remains difficult to ensure the effect of filtering and the continuity of production；
3rd, existing Technology for Heating Processing would generally not subsequently be filtered and directly carry out distillation processing, and the bits of generation can be blocked point
Evaporate bottom of towe；
4th, existing Technology for Heating Processing would generally not subsequently filter and directly carry out distillation processing, destroyed additive composition
Still in waste lubricating oil, these compositions can enter in the oil product distilled out, while can also block and corrode tower internals；
5th, heat treatment is combined by present invention process with propane extraction：Heat treatment has destroyed the addition in waste lubricating oil
Agent, drastically increases the effect of propane extraction；Propane extraction can make additive, the machine being deteriorated in used oil well again
Tool impurity and rotten component are precipitated out.Heat treatment is combined with propane extraction, can efficiently be handled useless lubrication, is to existing useless profit
Lubricating oil regeneration techniques is significantly improved.
Brief description of the drawings
Fig. 1 is process schematic representation of the invention.
In figure：A is that dehydrating tower, B are that heat exchanger, C are that heating facility, D are that heat treatment tower, E are de- Light ends tower, F
Be extraction tower, 1 be waste lubricating oil, 2 be dehydration after waste lubricating oil, 3 be heat exchange after waste lubricating oil（Before heat treatment）, 4 be by
Waste lubricating oil after heating, 5 be waste lubricating oil after heat treatment, 6 be waste lubricating oil after heat exchange（After heat treatment）, 7 be removing light group
Used oil after part, 8 be propane, 9 be extract, 10 be sediment.
Embodiment
Waste lubricating oil 1 enters heat exchanger B heat exchange after entering dehydrating tower A, removing moisture content, is set after heat exchange into heating
C is applied, heat treatment tower D is entered after being heated, heat exchanger B is entered after heat treatment, de- Light ends tower E is entered after heat exchange, takes off light
Enter extraction tower F after component；Propane enters extraction tower F；Extract is pushed up from extraction tower F to flow out, and sediment is from extraction tower F bottoms
Discharge.
Embodiment one：
125 DEG C of temperature, flow 1t/h waste lubricating oil enter after dehydrating tower A, removing 0.03t/h water, are arrived into heat exchanger B heat exchange
225 DEG C enter heating furnace C, are heated to after 345 DEG C and enter heat treatment tower D stops 1 hour, are exchanged heat subsequently into heat exchanger B
To 245 DEG C, into de- Light ends tower E, remove after 0.05t/h Light ends, 4.3MPa is boosted into extraction tower F through pump；Pressure
4.3MPa, 40 DEG C of temperature, flow 3t/h propane enter extraction tower F；Extract is propane 2.95t/h, oil 0.87t/h, from extraction
Outflow at the top of tower F is taken, sediment is destroyed additive, mechanical admixture, the mixture of gum asphalt, and mixed with propane,
Wherein, mixture is 0.05t/h, and propane is 0.05t/h.
