CN1032060C disclose a kind of from the heavy grease fraction method of separating naphthenic acid, this method adopts the naphthenic acid of the solvent removal heavy grease fraction of being made up of ammonia, second alcohol and water; CN 101200653A discloses a kind of method of utilizing membrane dispersion extractor to remove the acid of hydrocarbon ils PetroChina Company Limited., and the depickling solvent that this method adopts is that the petroleum acid sodium of 1～15% ammonia, 20～70% alcohol or 0.02～5% or 0.004～1% emulsion splitter, water three compositions in weight percentage of surplus combine by weight percent.Above-mentioned two kinds of methods do not relate to solvent desalination simultaneously, demetalization ionization.
CN1298813C discloses a kind of method that is used for treating oil by alkali washing, and this method adopts the alcohol solution of caustic soda, removes the acid of oil product PetroChina Company Limited., salt or metal ion.Caustic soda is a highly basic, and chemical industry equipment is had big corrosive nature, and this method makes in the pretreated oil product residual metal sodium ion and is difficult to remove simultaneously, influences the oil product course of processing, makes the practicality of this method be restricted.It is very necessary to remove the acid of oil product PetroChina Company Limited., salt and metal ion novel method when for this reason, developing a kind of easy through engineering approaches.
The utility model content
The purpose of this utility model is to provide a kind of petroleum acid, salt and metal ion device that removes simultaneously in the oil product, use this device and remove behind petroleum acid, salt and the metal ion in the oil product the not residual oxious component that processing has a negative impact to oil product in the oil product, solvent can recycling use.
Oil product solvent refining unit described in the utility model is by the oil product basin, solvent tanker, and the oil product transferpump, the solvent delivery pump, mixing tank, subsider constitutes; The delivery port of oil product basin is connected with the input aperture of oil product transferpump, the delivery port of oil product transferpump is connected with the input aperture of mixing tank, the delivery port of solvent tanker is connected with the input aperture of solvent delivery pump, the delivery port of solvent delivery pump is connected with the input aperture of mixing tank, the delivery port of mixing tank is connected with the inlet at subsider middle part, the upper liquid separating outlet at subsider top connects the oil phase vaporizer, the oil phase vaporizer is connected with self-cleaning oil or naphthenic acid storage tank, the oil phase vaporizer is connected with solvent tank by condenser simultaneously, the following separatory outlet of subsider bottom connects the solvent phase evaporation device, the solvent phase evaporation device is connected with naphthenic acid or self-cleaning oil storage tank, and the solvent phase evaporation device is connected with solvent tank by condenser simultaneously.
Oil product solvent refining unit described in the utility model is characterised in that: described oil product is crude oil or crude oil fractions.Described solvent is the alcohol solution of organic bases, and wherein, the mass concentration of organic bases is 0.4%～15%, and the mass concentration of alcohol is 20%～80%, and all the other are water.Organic bases is NH
3, a kind of in the methylamine, ethamine, quadrol, propylamine, Isopropylamine, Monoethanolamine MEA BASF, diethanolamine, trolamine, Propanolamine or the organic bases that forms of two or more combination of components arbitrarily, this organic bases can phase trans-substitution; Alcohol is C
1～C
3Methyl alcohol in the Fatty Alcohol(C12-C14 and C12-C18), ethanol, n-propyl alcohol, Virahol a kind of or the alcohol that forms of two or more combination of components arbitrarily, but this alcohol phase trans-substitution.
Oil product and solvent mix in mixing tank, the effect of mixing tank is to make oil product and solvent even, it can be line-blending, or static mixer mixes, or the micro mixer mixing etc., the mixing quality ratio of solvent and oil product is 1: 0.5～1: 100, the blended temperature and time is determined according to the viscosity of oil product and the needs of reaction, should mix fully as far as possible, reach higher depickling, desalination, demetalization ion effect.
Compound enters in the subsider and carries out the separation of finish natural subsidence according to the finish density difference, because its density of solvent of different types of oil product and different compositions is different, top in subsider obtains acting on less oil phase or the solvent phase of back density, and the bottom in subsider obtains acting on bigger solvent phase or the oil phase of back density.The oil phase that obtains steams contained solvent in the oil in vaporizer, become depickling, desalination and demetallated purification oil product, and the solvent that steams is recyclable recycling after being condensed into liquid phase; The solvent phase that obtains steams solvent and obtains the mixing petroleum acid of saliferous and metal ion simultaneously in vaporizer, the solvent that steams is recyclable recycling after being condensed into liquid phase.Subsider can also be incubated in preheating, and material temperature and settling time determine that according to oil phase and the isolating effect of solvent phase it is few to make oil phase contain solvent as far as possible in the subsider, and the solvent phase oil-containing is few, reaches higher separating effect.
