Description
Technical field
The invention belongs to chemical technology field, be specifically related to a kind of device removing former W/O and metal-salt.
Background technology
Be appreciated that the inorganic salts such as mechanical impurity, C1-C2 light hydrocarbon gas, water and MgCl2, NaCl, CaCl2 that can differ containing quantity from underground mining crude oil out.Though after the preliminary hydro-extraction of oil field, water content is down to < 0.5%, saltiness is down to < 50mg/l, but be mixed into moisture in oil field dewatering and desalting facility imperfection and carried of crude oil process, the crude oil entering refinery still contains moisture and the salt of inequality, it is that crystalloid is suspended in crude oil that salt removes small portion, and major part is soluble in water.Moisture again major part is dispersed in oil with microgranular, forms more stable Water in Oil emulsion.Wherein, containing metal-salt and water in crude oil, all causing very large harm to crude oil accumulating, processing, quality product and equipment etc., as increased the load of accumulating, processing units, affecting normal work even etching apparatus, the shortening on-stream time of atmospheric and vacuum distillation.For this reason, crude oil is after entering refinery, first must carry out desalting and dewatering, guarantee that water content reaches 0.1%-0.2%, saltiness < 5mg/L, for the refinery having residual hydrogenation or heavy oil catalytic cracking process, saltiness requires < 3mg/L or contains sodium amount < 1mg/L.
Because most of salt is soluble in water, while therefore dewatering, salt is also removed.In current refinery, the electric desalting technology that adopts removes the water and metal-salt that contain in crude oil more, in crude oil, specifically inject the fresh water of a certain proportion of low chlorine content, with the crystallization salt in dissolving crude oil, and diluent crude oil salt solution, form new milk sap.Then under certain temperature, pressure and emulsion splitter and high-voltage electric field effect, make small water droplet be gathered into large water droplet, because of density difference, make water droplet sedimentation from oil by gravity, be separated the object reaching desalting and dewatering.
Oil extraction enters the middle and later periods, and crude quality will constantly decline, and Desalting and Dewatering from Crude Oil difficulty strengthens further, and along with research deepens continuously, Dewatering and Desalting Technologies of Crude Oil will obtain tremendous development, the technology of efficient removal salt will constantly can occur and apply.
Based on crude character and de-rear salt content in crud oil water-content indicator, adopt one-level, secondary, three grades of electric desalting flow processs, generally adopt two-stage process at present, small portion three grades of flow processs.The general electric desalting technology in refinery is mix through crude oil pump after crude oil adds low chlorine content fresh water, emulsion splitter in proportion, and be heated to subscribe temperature through interchanger, one-level electrical desalter is entered from bottom, after high-voltage electric field, dewatered oil is drawn from tank deck, re-injects fresh water and emulsion splitter, and enters bottom secondary electrical desalter after mixing valve mixing, again dewatered by high-voltage electric field, after dehydration, crude oil flows out from tank deck and is desalted and dewatered crude oil.The water saliferous wherein deviate from secondary desalter is less, capable of circulation for single stage desalting tank, and brine waste is discharged from single stage desalting tank.Crude oil enters firsts and seconds desalter and all needs supplementary fresh water, in order to water content in crystallization salt in dissolving crude oil and increase crude oil, to increase the dipole coalescence power of water droplet.General water injection rate one-level is the 5-6%wt of crude oil, and secondary is 2-3%wt.
Such as, the method (application publication number: CN103450930A) of a kind of crude oil demetalization dehydration disclosed in Chinese patent literature, it adopts the fiber yarn of wire material or nonmetal wire material as the carrier at crude oil and metal remover two-phase mass transfer interface, metal-salt and metal remover is realized in crude oil in water-oil interface contact reacts by film mass transfer effect, metal ion is ionized or forms throw out, inner complex, thus dissolve or be distributed in water, finally by settlement separate profit.This method does not need high-voltage electric field effect, thus plays for electric desalting technology and greatly reduce power consumption, reduces chemical reagent usage quantity, reduces discharge of wastewater.Also just like a kind of crude oil membrane mass transfer pretreatment system (application publication number: CN203999513U) disclosed in Chinese patent literature, itself and slurry tank form fiber liquid film mass transfer unit, for Desalting and Dewatering from Crude Oil, described fiber liquid film mass transfer unit is set to one-level, secondary or three grades by combinations such as serial or parallel connections to meet Desalting and Dewatering from Crude Oil demand by it.
Though above-mentioned crude oil electric desalting dewatering technology utilizes tunica fibrosa mass transfer means, in conjunction with metal remover and crude oil upgrading system, the problem that preferably resolves that the emulsification that traditional electrical desalting technology exists is serious, plant running is unstable, power consumption is high, emulsion splitter consumption is large, running cost is high etc., but series-parallel connection causes complex operation, flow process complicated, not easily technology upgrading is carried out for traditional electrical desalting plant, needed for oily water separation, time of repose is still long, and cause equipment volume comparatively large, investment improves.
