Abstract

Paraffin suppressant - nanoparticulate admixtures are added to petroleum oils, such as crude or refined oils, to obtain treated petroleum oils. The treated petroleum oils obtain a viscosity that is reduced by 5% to 50%, and pour point that is reduced by 0.1 °C to 5 ºC compared to the same petroleum oil treated with the paraffin suppressant in the absence of the nanoparticulate, further where the comparison is made at a temperature between 60 ºC and -4 ºC. The paraffin suppressant - nanoparticulate admixtures also obtain decreased fouling of surfaces by paraffin waxes present in many petroleum oils, when compared to the same petroleum oil treated with the paraffin suppressant in the absence of the nanoparticulate.

Description

CHX0204WO (CXID24.27W0)PARAFFIN SI TPRFSSAN T ( AND METHODSTECHNICAL FIELD{00011 Crude oil is globally sourced from subterranean reservoirs using techniques such as drilling and hydraulic fracturing. As sourced from a reservoir, a crude oil typically includes linear, cyclic, and branched alkanes having the general formula CaH3n*2 wherein n is typically about 5-60, often 5-50; lower alkanes are produced from the reservoir as gases. Alkanes C5~ C 17 obtain a liquid phase over a range of use temperatures. However, higher molecular weight alkanes, such as Cl 8 (octadecane, melting point 28 - 30 °C) orC19 (nonadecane, melting point 33 °C) or higher linear alkanes have melting points that are greater than ambient or use temperatures in many cases. Some alkanes present in a crude oil can have melting points in excess of 60 °C. Accordingly, at temperatures of 60 "C and less, high melting alkane fractions in a crude oil can nucleate and crystallize, causing increased viscosity of the crude oil and / or precipitation of residue from the crude oil. The crystallized or precipitated residue is termed “paraffin” or “paraffin wax”.(0002] Transportation of crude oil products from a subterranean reservoir to a refining facility or other processing facility is accomplished by moving the crude oil through a conduit (such as a pipe) and into a containment for storage and / or transportation, such as a containment for storing and supplying the crude oil to one or more refining processes; or a containment associated with storage and transportation ofa crude oil via truck, railcar, ocean tanker, and the like. During the moving and / or storag e / transportation, the crude oil is often subjected to ambient temperatures between -40 °C and 60 °C, and accordingly paraffin residue is often deposited on the interior surfaces of conduits, and storage containments, and transportation containments carrying, or having carried, a crude oil. That is, paraffin tends to foul the interior surfaces of containments and conduits contacted by crude oil sources when a paraffin precipitate associates with and collects on the conduit or containment surface.{0003J The solidified paraffinic residue not only reduces the effecti ve volume of the structure within which it is contained, but also represents a loss of a valuable component from the body of the crude oil. Excessive paraffin wax buildup reduces the efficiency of transporting crude oil and leads to increased costs related to added downtime for cleaning of the pipes and / orvessels as well as disposal of residues removed from the vessel which increase environmental burdens. Further, some “high paraffin” crude oil sources inchide about 20 wt% or more, tsp to about 35 wt% paraffin content, which can solidify at one or more use temperatures to which the crude oil source is subjected after extraction from a subterranean reservoir. Such high paraffin crude oils are difficult to process due to significant paraffin fouling of surfaces contacted during the transportation and storage of the crude oil as well as surfaces contacted during processing thereof.

[0004] The precipitation of paraffin wax from a crude oil can be reduced by additives, called paraffin inhibitors, which interfere with the crystallization process of wax and / or obtain suspension or dispersion of wax crystals in the crude oil. Most paraffin inhibitors are polymeric. Examples of industrially useful paraffin inhibitors are copolymers of et hylene with one or more of vinyl acetate, acrylonitrile, or an a-olefln such as octene, butene, propylene, and the like; branched alkaryl condensation copolymers, such as alkylphenol formaldehyde copolymers; N- functioualized polyethyleneimines; and comb polymers having alkyl side chains, including alkylacrylamide, aciylate ester, and methacrylate ester homo* and copolymers in addition to “OMAC” copolymers, which are olefnvmaleate ester and olefln-maleimide copolymers.[0005| The deposition of paraffin wax from a crude oil source can also be reduced by additives, called “paraffin dispersants”, which operate not to prevent crystallization but rather to disperse wax and / or paraffin crystals that do form in the oil and thus also prevent paraffin deposition. Many paraffin dispersants are oligomeric or non-polymeric surfactan ts. Examples of paraffin dispersants include alkoxylated long-chain alkylphenols (c.g. ethoxylated or cthoxylated / propoxylaicd nonylphenol) and formaldehyde resins formed therefrom, alkylphenol formaldehyde resins, and ammonium salts of dodecyl benzene sulfonic acid (DDBSA). hi some cases, one or more paraffin dispersants are usefully combined with one or more paraffin inhibitors to provide more effective total treatment of foe paraffin present in the crude oil.

[0006] Prior to precipitation of paraffin from a crude oil, initial nucleation and growth of associated wax crystals causes the viscosity of the crude oil to increase; and this effect may be observed as a function of temperature. Accordingly, measuring the viscosity of a crude oil as a function of decreasing temperature provides as an effective technique to quantify the efficacy of a paraffin Inhibitor and / or a paraffin dispersant added thereto. Even after refining a crude oilio form one or more refined oils, viscosity of some refined oils can be observed to increase as a function of decreasing temperature. The lowest temperature at which a petroleum oik such as a crude oil or a refined oil, will pour (obtain gravity-induced flow) is its pour pointJ0007J Accordingly; “pour point depressants” is a term of art used in the industry to describe chemical additives used to facilitate the pumping, pouring, or other manipulation or use of petroleum oils at lower temperatures where the petroleum oil would otherwise have an unacceptably high viscosity, or even form a gel. Industrially, a pour point depressant is a chemical additive for reducing the pour point of refined oils, which can still form crystalline structures that result in increased viscosity - and even gel formation - at temperatures below about 20 °C, depending on the particular composition and properties of the specific petroleum oil. However, the pour point of a crude oil may be affected by the same crystallization mechanisms operable in connection with the pour point of a refined oil.|0008] Accordingly, in some cases, paraffin inhibitors and / or paraffin dispersants may also operate as pour point depressants in one or more petroleum oils selected from crude oils and refined oils. In a crude oil, mechanisms of inhibiting paraffin deposition or dispersing paraffin crystals that have formed may further operate to depress the pour point of the crude oil. Many commercially available pour point depressants have the same chemical composition as the paraffin inhibitor polymers listed above. Additionally, a limited number of nonpolymeric compounds based on fatty acid esters, such as pheuyitristeary'loxysilane pentaerythritol tetrastearate, are also effective pour point depressants.While these conventional chemical additive technologies for preventing hydrocarbon crystal formation and / or dispersing hydrocarbon crystals in petroleum oils have been known to work for many years, there remains a need in the industry for improved efficacy of such additives, for improved performance and / or allowing for an lower amount of the additive to be used while achieving a commensurate effect. Accordingly, there remains a need in the industry for compositions and methods for obtaining decreased precipitation and fouling by paraffins and higher alkanes present in petroleum oils, and / or decreased pour points in petroleum oils.SUMMARY|OQ10] Disclosed in first embodiments herein are paraffin suppressant compositions comprising, consisting essentially of, or consisting of one or more nanoparticulates combinedwith one or more paraffin suppressants.

Furthermore, the treated petroleum oils are isotropic dispersions. It is an unexpected advantage to be able to admix nanoparticulates, especially nanoparticulates comprising orconsisting essentially of highly polar compounds such as silica and alumina and aluminosilicate, with hydrocarbon compounds such as petroleum oils to provide isotropic mixtures. In the past, these materials have been considered to be incompatible, and an emulsion was required to combine them. The addition of water to a petroleum oil is undesirable, and accordingly Chinese application CNl 10922955A describes emulsion polymerization of octadecyl methacrylate, maleic anhydride, styrene, and acrylamide in the presence of a functionalized silica colloid, in order to graft polymerize an oil “soluble copolymer to silica, rendering the grafted silica oil dispersible and enabling the use of the polymer-grafted silica as a paraffin inhibitor. Emulsion polymerization obtains bonding of the hydrophobic monomers, such as octadecyl methacrylate, to the hydrophilic silica surface. However, the water must then be removed prior to adding the grafted material to a petroleum oil. Further, the grafting methodology is limited io those polymers suitable to obtain grafting to silica, and further are suitable for addition to an emulsion, or for emulsion polymerization, or for grafting to an aqueous colloidal particulate.(Oil 9| Unexpectedly, we have found that dry nanoparticulates and organosol type nanoparticulates may be carefully admixed with paraffin suppressants in non-aqueous solvents to provide shelf-stable paraffin suppressant concentrates that are isotropic dispersions. Accordingly, in embodiments, the paraffin suppressants of first embodiments exclude water, or substantially exclude water; and so no water is present and no water needs to be removed from such a paraffin suppressant composition prior to use thereof to form the treated petroleum oils of fourth embodiments herein. Accordingly, the treated petroleum oils of fourth embodiments are admixtures are easily formed using any paraffin suppressant, including those suited for graft polymerization as well as phenolic resins and polyethyleneimine polymers that are not suitable for graft polymerization to a nanoparticulate coupling agent, and / or are not suitable for use in aqueous emulsions as directed by CN110922955A to obtain compatibility of the silica nanoparticulate.
