Definitions
- This invention relates to the field of the oil and petrochemical industry, in terms of the use of pipeline transport of liquid hydrocarbons, namely, to methods of reducing their hydrodynamic resistance during transportation.
- the proposed invention relates to anti-turbulent additives (PTP), which reduce the hydrodynamic resistance to turbulent flow of hydrocarbon fluids in pipelines, in particular, to rapidly dissolving and soluble in hydrocarbons, dry dispersions (SD PTP) of high- and ultra-high molecular weight (SVM) (co) polymers, reducing hydrodynamic resistance to turbulent flow in pipelines and containing complex anti-agglomerators and other additives.
- PTP anti-turbulent additives
- SD PTP dry dispersions
- SVM ultra-high molecular weight
- a known method of producing a polymer including obtaining a finely divided polymer, soluble in hydrocarbon liquids.
- the polymer is synthesized by the (co) polymerization of higher alpha-olefins using a Ziegler-Natta catalyst.
- a (co) polymer of higher alpha-olefins a block polymerization product is used.
- a fine dispersion of a polymer is obtained by thermal reprecipitation of a polymer in a liquid that is a nonsolvent for the polymer at room temperature and is capable of dissolving it at an elevated temperature (see patent RU 2481357 C1, 05/10/2013).
- a known method of producing a non-aqueous suspension that reduces the resistance to flow of hydrocarbons in pipelines including a method of forming a stable non-aqueous suspension of a solid, soluble in hydrocarbons, anti-turbulent additive based on polyolefin, capable of reducing the hydrodynamic resistance to the flow of hydrocarbons, in pipeline, comprising (a) fine (low temperature) grinding of the polyolefin in the presence of a separating agent to obtain a free flowing polyalphaolefin-based material coated with said separating agent, and b) dispersing the coated polyalphaolefin particles in a substantially non-aqueous suspension medium selected from the group consisting of higher alcohols ( ⁇ 14 C carbon atoms) and glycols ( ⁇ 14 C carbon atoms), and dipropylene glycol methyl ether, tripropylene glycol methyl ether, tetrapropylene glycol methyl ether or eth
- the closest in essence and the achieved technical result is a method for producing an agent for reducing the hydrodynamic resistance of a hydrocarbon flow (see patent RU 2599986 from 20.10.2016), which is a stabilized powdery high molecular weight polyalphaolefin.
- the method includes polymerization of higher alpha-olefins in fluorinated organic compounds using a titanium-magnesium catalyst modified with an electron-donor compound, followed by isolation of powdered polyalphaolefin and stabilization of the latter by adding an anti-agglomerator.
- the electron donor compound is a glycol ether, phthalic acid ester.
- the synthesis is carried out at a given ratio of the components of the system.
- the agent for reducing hydrodynamic resistance is characterized by the ratio of components by weight,%: polyalpha-olefin 80-90%, anti-agglomerator 10-20%.
- the disadvantage of this method and its analogs is the low energy efficiency of the method, since there is an interruption of the polymerization process upon reaching an average conversion of 40-95%, the addition of a dispersion medium, including an anti-agglomerator, decantation of the polyalpha-olefin suspension, washing of the (co) polymer suspension using filtering materials, vacuum drying at a temperature of 40-60 ° C to remove unreacted monomer and residual amounts of halogenated organic solvents.
- the resulting material cannot be used to feed liquid hydrocarbons transported through a pipeline into a stream without a carrier fluid.
- a significant difference is the use of a finely dispersed polymer powder with particle sizes from 10 to 1500 microns, and its processing with auxiliary materials from the group of monofunctional heteroatomic organic compounds, preferably higher fatty alcohols, and bifunctional heteroatomic organic compounds, preferably derivatives of glycols, with a carbon skeleton of 3 to 16 units with the following compositional distribution, wt%:
- Finely dispersed polyalphaolefin powder from 75 to 90
- Monofunctional heteroatomic organic compound with a carbon skeleton from 3 to 16 units from 1 to 10
- the product thus obtained has satisfactory mechanical properties and can be used to feed a hydrocarbon liquid transported through a pipeline into a flow using a metering device designed to handle powdered polymer materials.
- the objective of the invention is to obtain a reagent (anti-turbulent additive) with a high content of the active base to reduce the hydrodynamic resistance of a flow of liquid hydrocarbons, amenable to dosage in powder form.
- the technical result of the invention is to obtain a product characterized by a high, not less than 75 wt%, active substance content - ultra-high molecular weight polyalphaolefin, which is stable and amenable to metering into the pipeline of transported oil or gas condensate at high pressure by means of any known metering device designed for working with powder materials , thereby allowing to achieve a decrease in the resistance of the flow of the pumped oil or gas condensate, as well as to reduce the cost of transporting oil and gas condensate.
- a reagent is obtained for reducing the hydrodynamic resistance of a turbulent flow of liquid hydrocarbons in pipelines - an anti-turbulent additive, with a high content of an active base, at least 75 wt% polymer content, by mixing a polymer with the properties of reducing the hydrodynamic resistance of a turbulent flow of liquid hydrocarbons, sizes 10 - 1500 microns, obtained by any known method, with solvents that do not dissolve it, with the following ratio of components in composition, wt%:
- Monofunctional heteroatomic organic compound with a carbon skeleton from 3 to 16 units from 1 to 10
- the polymer is blended with polymer-non-dissolving solvents, preferably using mixing equipment for powder polymer materials of any design.
- the polymer powder is mixed with a mixture of glycol with the number of carbon atoms from 2 to 12 and fatty alcohol with the number of carbon atoms from 4 to 16 in the ratio polymer powder / mixture of glycol and fatty alcohol - 85 wt. P. / 15 wt. H. ...
- the product obtained by the described method is preferably fed into the flow of a hydrocarbon liquid transported through a pipeline using a metering device that mechanically transfers the product material by means of a screw screw or a screw feeder, for example, a screw extruder for polymeric materials, either directly into the hydrocarbon liquid stream, or into an intermediate container for mixing the material with the liquid flow and directing the resulting mixture into the main flow of the pipeline.
