Abstract
The invention discloses a scale inhibitor for preventing deposition of barium and strontium scales, and a preparation method thereof. The scale inhibitor is composed of dodecyl amino ethyl phosphate, myristyl amino ethyl phosphate, potassium iodide, ethylenediamine tetrapropionic acid tetrasodium salt, distilled water, hexamethylene diamine tetra(methylenephosphonic acid), vitamin A, vitamin C, polysuccinimide, ethanol and styrene. The above product prevents deposition of barium and strontium scales of oil products, and prolongs the pump checking period of an oil well 1-3 times; the use amount of the scale inhibitor is small and is 1-5mg/L, and the scale inhibition rate still is 96-100% after being disposed at 60-80DEG C for 1 month.
Description
Technical field
The application belongs to environmental protection reagent process field, particularly relate to a kind of environmental protection, corrosion inhibition good prevent barium strontium dirt deposition Scale inhibitors and preparation method thereof.
Background technology
Scale inhibitors (scaleinhibitor): be the insoluble inorganic salt had in energy disperse water, prevention or the precipitation of interference insoluble inorganic salt in metallic surface, fouling function, and maintain the class medicament that hardware has good heat-transfer effect.Cold exchange device antiseptic corrosion inhibitor is with epoxy resin and specific amino resin for base-material, and it is formulated to add the appropriate various auxiliary agent such as various antirust, anticorrosion, is single component.It has excellent shielding, impervious, rustless property, good scale inhibition, thermal conductivity, the performances such as excellent weak acid resistant, highly basic, organic solvent, its strong adhesion, and rete is bright, pliable and tough, fine and close, hard.
The result of dissemination stops into dirt interparticlely contact with each other and condense, thus can stop the growth of dirt.Becoming dirty particle can be calcium, magnesium ion, can also be dust, silt or other water-insolubles.Dispersion agent is the polymkeric substance with certain relative molecular mass (or polymerization degree), and the height of dispersing property is closely related with the size of relative molecular mass (or polymerization degree).The polymerization degree is too low, then few by absorption divided particles number, dispersion efficiency is low; The polymerization degree is too high, then too much by absorption divided particles number, water body becomes muddy, even forms flco (effect is now close with flocculation agent).Compared with sequestering action, dissemination is efficient.In middle high hardness water, the divergent function of Scale inhibitors plays a major role.
Efficient molten zinc agent is that one is compounded with machine phosphonic acid class anti-incrustation corrosion inhibitor, and the steady zinc ability of molten zinc exceedes conventional organic phosphine, at 250 DEG C, still can play good corrosion-mitigation scale-inhibition effect, still very stable at a high ph, not easily decomposes under general light and heat condition.Stable chemical nature in water, not facile hydrolysis.Can belong to ion with underwater gold, especially calcium ion forms six annulus inner complexs, thus the good scale inhibition effect of tool the obvious threshold effect of tool, when with other water conditioner compound use, shows desirable synergistic effect.
Polyamino polyether base methylenephosphonic acid PAPEMPPAPEMP is latest generation water conditioner, there is very high chelating dispersing property and the scale-inhibiting properties of very high calcium tolerance and excellence, this medicament can be used as the anti-incrustation corrosion inhibitor of recirculating cooling water system, is specially adapted to high rigidity, high alkalinity, the recirculating cooling water system of high pH and oil-field water process.Excellent to the scale-inhibiting properties of calcium carbonate, calcium phosphate, calcium sulfate, effectively can suppress the formation of silicon dirt simultaneously, and there is the effect of satisfactory stability metal ion as zinc, manganese, iron.PAPEMP is used for the film Scale inhibitors of reverse osmosis system, the scale inhibition of the supersalinitys such as multi-stage flash system, high concentrtion, high-temperature systems and inhibition (scale inhibition as coal carburetion system high temperature height muddy water system), textile auxiliary and paper making additive (yellowing inhibition agent), alternative EDTA, DTPA, NTA etc.
Under hexapotassium HDTMPA normal temperature, HDTMPA is white crystalline powder, is slightly soluble in water, and its solubleness is at room temperature less than 5%.HDTMPA can suppress the generation of various incrustation scale (as calcium carbonate scale, calcium sulfate scale, barium sulfate scale and Ferric oxide scale etc.), but is mainly used to prevent calcium sulfate and barium sulfate scale in water treatment.In various organic phosphoric acid, the performance of its resistance calcium sulfate scale is best, and not only scale inhibition performance is high, and working lipe is long, is therefore specially adapted in the extrusion process in oil field.HDTMPA also can be used in boiler water processing.
PAPE is a kind of novel water treatment agent, has good scale inhibition and corrosion inhibition.Owing to introducing multiple polyoxyethylene groups in molecule, not only increase corrosion inhibition, also improve the dispersive ability of scale inhibition to calcium dirt and silt.To domestic existing Scale inhibitors in uncontrollable water barium, strontium dirt deposition have excellent restraining effect; also excellent scale effect is had to difficulty soluble salt depositions such as the calcium carbonate in water, calcium sulfate; have galvanic protection effect to steel, corrosion mitigating effect is better than domestic existing like product.The water stablizers such as PAPE and polycarboxylate, organic phosphonate, inorganic phosphate, zinc salt are well miscible.PAPE is used for the Scale inhibitors (special recommendation is as the surrogate of NalcoVisco953) that oil-field flooding gathers, the corrosion inhibiting and descaling agent of industrial colling process.
2-hydroxyethylidene diphosphonic acid guanidine-acetic acid HPAAHPAA chemical stability is good, not facile hydrolysis, not easily destroy by soda acid, safe and reliable, nontoxic pollution-free, HPAA can improve the solubleness of zinc, have extremely strong corrosion inhibition, HPAA corrosion inhibition is higher than HEDP, EDTMP 5 ~ 8 times.The organic inhibition dirty-proof agent excellent property that HPAA forms together with low-molecular-weight polymkeric substance.And universal along with humanity concept, and the formation of novel harmonious society, design a kind of nontoxic, odorless, environmental protection and corrosion inhibition good prevent from barium strontium from depositing Scale inhibitors and preparation method thereof being very important.
