Description
Technical field
The present invention relates to a kind of under liquid-phase condition the adsorption refining method of liquid hydrocarbon.
Background technology
Liquid hydrocarbon be crude oil once, the by product in secondary and the three times oil refining course of processing, devices such as catalytic cracking, hydrocracking, delayed coking ethylene cracker are the main sources of liquid hydrocarbon.Liquid hydrocarbon is through producing liquefied petroleum gas (LPG) and industrial chemicals such as propylene, propane and butylene.
Stipulate in the quality index of liquid hydrocarbon: evaporation residue is not more than 0.05mL/100mL, oil stain is observed and passed through.Liquid hydrocarbon residue and oil stain are defective, very easily produce potential safety hazard in the use of liquid hydrocarbon.
Evaporation residue in the liquid hydrocarbon mainly is: impurity such as moisture, solid particulate matter and oil stain.The composition of the contained oil stain of liquid hydrocarbon is carbon 6 to hydro carbons or non-hydrocarbons material, the especially sulfur-bearing of carbon 46, contains oxygen, nitrogenous polar material.Moisture and solid impurity in the evaporation residue of liquid hydrocarbon influence the evaporation of residual amount, but just can remove by methods such as sedimentation or filtrations.And the oil stain in the liquid hydrocarbon evaporation residue not only influences the evaporation of residual amount, and is to cause the underproof basic reason of oil stain.
In existing liquid hydrocarbon production technique, the residue of liquid hydrocarbon be by produce in the course of processing or transferpump lubricating oil sneak into or reason such as liquefied petroleum gas (LPG) storage vessel long-term accumulation heavy hydrocarbon causes.The reason that produces owing to the residue of liquid hydrocarbon is comparatively complicated, and the composition of oil stain also has very big difference, causes the liquid hydrocarbon oil stain to remove and has difficulties.The method of generally using is at present, in the following process process of liquid hydrocarbon such as sweetening process, water washing process, adopt and frequently change water and change alkali lye and, remove intrasystem part oil stain methods such as alkali lye carry out that back suction is carried, thus the oil stain content of minimizing liquid hydrocarbon.These methods expend a large amount of water and alkali lye, have increased the discharging of energy consumption and waste liquid, and can not solve the defective problem of oil stain.
Summary of the invention:
The invention provides a kind of under liquid-phase condition the adsorption refining method of liquid hydrocarbon.Employing this patent method can remove moisture, the oil stain impurity in the liquid hydrocarbon effectively, solves liquid hydrocarbon evaporation of residual amount, the defective problem of oil stain.And present method does not have the discharging of waste water, waste lye, and is environmentally friendly.
The present invention is achieved in that liquid hydrocarbon successively by the compound adsorbent bed, impurity such as the contained moisture of adsorbents adsorb liquid hydrocarbon, oil stain under liquid-phase condition, thus liquid hydrocarbon is made with extra care.The processing condition of absorption are: adsorption temp-25 ℃～50 ℃, adsorptive pressure 0.1 MPa～2.5 MPas, weight space velocity 0.5 hour
-1～20 hours
-1
Technical characterictic of the present invention is: it is gac and granular carclazyte that sorbent material adopts compound adsorbent.Wherein gac is the gac that can touch the mark and require with raw material such as coal raw materials, wood material or refinery coke, petroleum pitch or the preparation of their mixture.The index of gac is as follows: 1000～1500 meters of specific surface areas
3/ gram, 0.6～1.1 centimetre of pore volume
3/ gram, ash content 4～10%, intensity 90～98%, 950～1200 milligrams/gram of iodine sorption value, 200～300 milligrams/gram of methylenum coeruleum adsorptive value, tetracol phenixin adsorption rate 60～70%.The index of granular carclazyte is: 100～300 meters of specific surface areas
2/ gram, 0.6～1.0 N/of crush strength, tap density 700-1000 grams per milliliter.
Technical characterictic of the present invention is: adsorber is axially-located bed.Compound adsorbent gac and granular carclazyte in adsorber, both ratios are: the ratio of the loading height of granular carclazyte and the loading height of gac is 0.1～3.Liquid hydrocarbon is successively by active carbon bed and carclazyte bed.
Technical characterictic of the present invention is: adsorber is under the weight space velocity condition of the best, and its aspect ratio can be regulated by changing the gac and the kind of granular carclazyte and the granular size of sorbent material.The regulation range of aspect ratio is 3～30.Use has the gac and the granular carclazyte of better absorption property, under the situation that guarantees the oil stain removal effect, can adopt the lower adsorber of aspect ratio.Adopt little gac and the granular carclazyte of granularity, under the situation that guarantees the oil stain removal effect, can reduce the aspect ratio of adsorber.
Advantage of the present invention is: adopt the refining liquid hydrocarbon of present method, impurity such as the moisture in can the effective elimination liquid hydrocarbon, oil stain have fundamentally solved the defective problem of liquid hydrocarbon evaporation of residual amount and oil stain.Adopt fixed-bed adsorber, gac and granular carclazyte compound adsorbent, technology is row, with low cost easily.The equal repeated use of regenerating of gac and granular carclazyte is eco-friendly technological process.
