Description
Technical field
The present invention relates to oil refining field, in particular it relates to a kind of recovery method of clear tank oil.
Background technology
There is the clear tank oil of different storages in Technologies in Petrochemical Industry refinery at present, it is most of for original due to being removed in the clear tank oil in refinery
Oily outer, also containing a large amount of mechanical admixtures, gum asphalt impurity, composition is sufficiently complex, and directly entering atmospheric and vacuum distillation unit freshening can make
Quickly raised into Crude Desalting System electric current, it is de- after saliferous, it is aqueous it is exceeded, draining oil-containing is exceeded etc., and impact, refinery are difficult to conventional
Means high efficiente callback is utilized, and substantial oil is wasted, and risk is brought to refinery's safety and environmental protection.
Currently, petrochemical industry recycles for the clear tank oil in refinery and there are no industrialization report.Refinery's generally use at present
Processing method have it is following several：
(1) method of heating sedimentation crude separation, i.e.,：Clear tank oil collect among big tank, in big tank heat after by
Prolonged natural subsidence effect so that the preferable crude oil of small part is floated at the top of liquid level, for reaching the mesh of clear tank oil recovery
's.And remaining most of effect of the clear tank oil because depending merely on sedimentation containing substantial oil can not separate the crude oil for meeting to require, only
It can be dispatched from the factory as refinery's discarded object in the form of waste.The method processing time is long, takes refinery's tank holds resource, reclaims simultaneously
Efficiency is very low, causes crude resources and greatly wastes.
(2) method centrifuged, i.e.,：By three phase separation horizontal screw centrifuge by the mechanical admixture in clear tank oil, water, oil
Simple separation is carried out, but fails to remove colloid, asphalitine in clear tank oil, enters atmospheric and vacuum distillation unit freshening and still causes Crude Desalting System
Impact, can not smooth freshening.

A kind of the defects of decompressor freshening, there is provided recovery method of clear tank oil.
To achieve these goals, the invention provides a kind of recovery method of clear tank oil, wherein, this method includes：Will
With medicament precipitation reaction occurs for clear tank oil, and obtained reaction product is carried out into separation of solid and liquid, by the separation of solid and liquid process points
The liquid phase separated out carries out water-oil separating, and then the oil phase isolated in the oil water separation process is centrifuged.
In the recovery method of clear tank oil of the present invention, all kinds of mechanical admixtures, colloid emulsification in the clear tank oil
Precipitation reaction occurs for thing and medicament, obtained reaction product is carried out into separation of solid and liquid, the mechanical admixture in the clear tank oil
And the colloid emulsion is discharged in the form of sediment solid phase greasy filth, liquid phase part is oil water mixture, and the profit is mixed
Compound carries out water-oil separating, and the aqueous phase isolated in the oil water separation process is discharged in the form of sewage, then by the profit
The oil phase isolated in separation process is centrifuged, and the light phase component isolated in the centrifugal separation processes is light oil
Phase, the miscellaneous content of water of the light oil phase is low, can enter refinery's atmospheric and vacuum distillation unit and carry out freshening and device is not impacted.
Method provided by the invention can efficiently, quickly, thoroughly reclaim clear tank oil, while method is simple, equipment is easy for installation,
Also can skidization design, operation is flexible.The miscellaneous content of water that the light oil phase that clear tank oil obtains is reclaimed in this method processing is 0.5 body
Product %-1.0 volume %, reach the volume % of the miscellaneous content of requirement water into atmospheric and vacuum distillation unit freshening≤1.0, and clear tank oil recovery rate is reachable
More than 95%.
In the recovery method of clear tank oil of the present invention, the sewage indices discharged in the oil water separation process
Meet environmental requirement standard (COD≤800mg/l, pH 6-9, NH3- N≤40mg/l), draining oil-polluted water system can be discharged into
System.In the separation of solid and liquid process, the band hydrogen sulfide oil gas with the one piece of discharge of solid greasy filth enters deodorizing equipment, avoids
Pollution is produced to environment.Whole process reaches the purpose recycled to clear tank glossy dark green mulberry.
Other features and advantages of the present invention will be described in detail in subsequent specific embodiment part.
