Abstract
The invention discloses a preparation method of a water-soluble oil slurry antiscale. The method comprises the following steps: (1) generation of phosphate: pumping isopropyl alcohol into a reaction kettle, raising the temperature to 50-70 DEG C, then, slowly adding phosphorus pentoxide, raising the temperature to 110 DEG C or so, reacting for 4-5h, cooling to the temperature below 50 DEG C, and discharging materials for later use; and (2) compounding: pumping a solvent, ethanol, diethylene glycol, alkyl benzene sulfonic acid and the phosphate obtained in (1) into the reaction kettle in sequence, fully stirring, cooling to the temperature below 10 DEG C, slowly adding amine, stirring for 1h at 18-22 DEG C, discharging materials into a storage tank, and standing for one week to obtain the water-soluble oil slurry antiscale. The water-soluble oil slurry antiscale disclosed by the invention can be favorably diluted with water by a user, and is uniform in distribution and increased in flowability due to increase of the water content, so that the capacity of processing raw oil is improved, and the effects of scale dissolving, scale resisting and aggregation resisting are further enhanced; and the water-soluble oil slurry antiscale has the advantage of reduced production cost, compared with the oil-soluble antiscale.
Description
Technical field
The present invention relates to a kind of preparing technical field of Scale inhibitors, specifically a kind of preparation method of water-soluble slurry oil Scale inhibitors.
Background technology
In recent years, along with variation and the complete processing of catalytically cracked stock becomes dark, Fcc Slurry System equipment scaling, the coking imagination cause the slurry heat-exchanger Efficiency Decreasing, normal production and the long-term operation of device have been affected, and directly affect the safe operation of equipment, cause device to be forced to stop production when serious.
The different angles such as oil refining worker slave unit, technique, operation, the way of a series of solution scale problems has been proposed, as reduce fractionator bottom temperature, the minimizing residence time, raising slurry oil flow velocity, installation slurry oil strainer etc. and all obtained certain effect, but all exist certain limitation.At the micro-slurry oil Scale inhibitors of the middle adding that processes raw material, to suppress the formation of dirt.
In refining of petroleum and petrochemical process, oil product needs heating, cooling, cracking, separation to produce various petrochemicals.When liquid hydrocarbon with heat the hardware Surface Contact time, often have dirt to separate out, and adhere to equipment surface.In the oil refining process, equipment incrustation will cause plant energy consumption to increase.When the heat of loss can not replenish with additive method, product separation can be affected.Because incrustation increases the pressure of system, limited the treatment capacity of device simultaneously.In oils industry, the fouling meeting of vaporizer causes residual molten the increasing of crude oil, causes that easily evaporation " liquid flooding " heat energy consumption increases, and dregs of rice Residual oil increases, and reduces quality of crude oil.
Existing Scale inhibitors mostly is greatly oil soluble, and is dispersed and mobile bad often take diesel oil, kerosene, hydro carbons etc. as solvent, affected its scale inhibition effect, and cost is higher.Usually need to add very a large amount of Scale inhibitorss and just can reach corresponding scale inhibition effect.Scale inhibitors should have antioxidant property, in the presence of oxygen, be heated, the katalysis of light, metal, hydrocarbon key in the oil product is damaged, the terminating chain reaction makes it to form high polymer, stops the polymerization of hydrocarbon molecule, reduce the formation of organic deposition, to reach the purpose that stops organic deposition to generate.Scale inhibitors also should have good dispersing property, can stop the gatherings such as the catalyst fines that is suspended in the slurry oil, corrosion product, salt, increases and deposits with the restriction particle.Polar group in the Scale inhibitors can align in the metallic surface of equipment and pipeline, stops the deposition of dirt.
Summary of the invention
The object of the present invention is to provide a kind of preparation method of water-soluble slurry oil Scale inhibitors.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of preparation method of water-soluble slurry oil Scale inhibitors is characterized in that comprising the steps:
