Abstract
A kind of process for refining of use producing lubricating oil from waste engine oil base oil.It becomes colourity after thick fraction oil refining processing obtained by vacuum distillation suitable for used oil and is not more than No. 1.5, and free from extraneous odour, clear meets lube base oil requirement, yield is up to more than 80%, and this method is made up of three parts：Degumming, high temperature active be clay-filtered and clarification.
Description
Technical field
The invention belongs to refining of petroleum products clarification technique, more precisely slightly evaporated using used oil vacuum distillation gained
The process for refining of the production lube base oil of part oil.
Background technology
Current producing lubricating oil from waste engine oil base oil, is passing through vacuum distillation（Including molecular distillation, scraper plate falling-film distillation
Deng）Obtained thick fraction oil colourity is deep, generally higher than No. 6, or even No. 10；There is stink, some are muddy, it is necessary to further carry out
It is refined.
General refine has three kinds of methods：1st, sulfuric acid process, due to the limitation of environmental law, has been eliminated；2nd, decolouring sand absorption method,
But loss is big, cost is high, it is also difficult to which industrialization is used；3rd, hydrogenation method, because the source of used oil is complicated, thick fraction oil entrainment is not
Same harmful substance, it is difficult to choose suitable catalyst.
The present invention is complicated for the source of used oil, and the oily impurity composition of the thick fraction obtained by vacuum distillation is complicated, using one
A little existing oil refinery technique simple combinations：Degumming, high temperature active are clay-filtered, clarification, efficiently solve thick fraction olein
Problem processed, obtain meet lube base oil to colourity, smell, outward appearance requirement.
The content of the invention
It is an object of the invention to provide a kind of method is simple, product yield is high, low produced with used oil of running cost is moistened
The process for refining of lubricant base oil.
The process for refining for a kind of use producing lubricating oil from waste engine oil base oil that the present invention is provided, by used oil through vacuum distillation
The thick fraction oil of gained is handled and obtained through following step：
Degumming：Thick fraction oil is heated to after 110~130 DEG C of dehydrations, 70~90 DEG C are cooled to, the oily gross mass of thick fraction is added
0.5%~4% electrically charged metal salt, is stirred 30~60 minutes, and standing obtains degummed oil in 1~3 hour through deslagging；
High temperature active is clay-filtered：The atlapulgite of the oily gross mass 4%~8% of thick fraction is added to degummed oil, be heated to 140 DEG C~
200 DEG C, stir 30~90 minutes, be naturally cooling to 135 DEG C, filter to obtain atlapulgite refined oil；
Clarification：The clarification refining agent of the oily gross mass 3%~6% of thick fraction is added to atlapulgite refined oil, is stirred at 60~90 DEG C
Mix after 30~90 minutes, constant temperature stands 1~3 hour, then filter and obtain this product.
The present invention utilizes electrically charged metal salt, and such as TiCl4, AlCl3, FeCl3 can be with the oily studies on asphaltene of thick fraction, glue
Matter flocculation sediment is removed.The present invention is TiCl4, AlCl3 or FeCl3 for the electrically charged metal salt of thick fraction degumming of oil.
The heating-up temperature of high temperature active carclazyte of the present invention for removing oil product colloid, basic nitrogen influence it is larger, only compared with
Refined under high-temperature, colloid, basic nitrogen could be removed more completely, oil product is decolourized, therefore deodorization temperature is selected 140~200
℃。
The present invention clarification process be that use can make oil product further decolourize, be deodorized, make oil product clarification, it is transparent, the present invention use
The clarification refining agent for refining breakdown of oil in atlapulgite is macro porous silica gel or wood activated charcoal.
Why colourity is deep for thick fraction oil, and smell is smelly, turbid appearance, is, because of in vacuum distillation, to be entrained with asphalitine,
Colloid（Including basic nitrogen）, condensed-nuclei aromatics and petroleum oxidate hydrocarbon cause.The present invention is clay-filtered, clear by degumming, high temperature active
Clear process, effectively makes thick fraction oil decolorization, deodorization, clarification, and product yield is up to more than 80%, and running cost is low, and industrialization can
OK.
