Abstract
The invention discloses a reaction type crude oil flow modifying agent containing a carboxylic acid organic macromolecule and relates to the technical field of a common chemical method, a preparation method of organic macromolecule compounds and a pipeline system. The reaction type crude oil flow modifying agent comprises the following components with total weight of 100 percent: 2-25 percent of organic macromolecule containing carboxylic acid, 5-30 percent of surface active agent and 20-70 percent of micromolecule organic matter. The modifying agent can react with polar groups of colloid and asphaltene in crude oil, such as alcohol, amine, carboxylic acid, and the like. Therefore, the invention has obvious improvement on the sedimentation, solidification and flowability of the crude oil.
Description
Technical field
The present invention is a kind of carboxylic acid organic macromolecule reaction type crude oil flow modifying agent that contains.Relate to general chemical process, their preparation (preparation of organic macromolecule compound) and tubing system technical field.
Background technology
The crude oil flow modifying agent of pour point depression of crude oil and pour point depression (also claiming pour point depressant) is the energy-saving and cost-reducing a kind of otherwise effective technique of pipeline oil.Though existing pour point depressant contains polar group, but with crude oil in colloid, bitum polar group form hydrogen bond, make certain pour point depression and mobile the improvement.But because of not reacting, so pour point depression and mobile the improvement are limited with colloid, bituminous matter in the crude oil.
Summary of the invention
The objective of the invention is to invent a kind of pour point depression and better contain the carboxylic acid organic macromolecule reaction type crude oil flow modifying agent with mobile the improvement.
The present invention is made up of the organic polymer that contains carboxylic acid, tensio-active agent and small organic molecule.In gross weight is that the ratio of each component in 100% is: the organic polymer 2%～25%, tensio-active agent 5%～30% and the small organic molecule 20%～70% that contain carboxylic acid.
Wherein:
The organic polymer that contains carboxylic acid is that monomer such as alkene, acrylate, ethylene vinyl acetate, vinylbenzene, maleic anhydride (maleic acid), acrylamide, vinyl cyanide and Acrylic Acid Monomer carry out polymerization and form binary, ternary or tetrapolymer; The end group that contains in the derivative of above-mentioned polymkeric substance is a carboxylic acid;
Tensio-active agent is polyoxy alkyl ethoxylated carboxylic acid, polyoxyethylene alkane polyoxypropylene alkylbenzene phenolic ether carboxylic acid etc.;
Small organic molecule is alkyl carboxylic acid (oleic acid, a stearic acid etc.), linseed oil fatty acid, alkyl acid, naphthenic acid etc.;
Organic solvent is: alkane such as gasoline, diesel oil, sherwood oil etc., aromatic hydrocarbon such as dimethylbenzene, heavy aromatics, C9 aromatic hydrocarbons, C10 aromatic hydrocarbons.
The present invention contains the one-component of above-mentioned high molecular polymer, tensio-active agent and organic molecule or mixture, and it can react as alcohol, amine, carboxylic acid etc. with colloid, bitum polar group in the crude oil.So the present invention is to pour point depression of crude oil and mobile the improvement obviously.
Embodiment
Embodiment. olefinic monomer and Acrylic Acid Monomer carry out polymerization and form binary, ternary or tetrapolymer; The end group that contains in the derivative of this polymkeric substance is a carboxylic acid; Synthetic method is for to carry out radical polymerization in the presence of the Diisopropyl azodicarboxylate initiator, temperature of reaction is 100 ℃, and molecular weight is 0.5～10.0 * 10
4, wherein acrylic acid content 20%; In gross weight is in 100%, and the organic polymer that contains carboxylic acid of formation accounts for 5%; Tensio-active agent selects polyoxy alkyl ethoxylated carboxylic acid, accounts for 25% of gross weight; Small organic molecule selects linseed oil fatty acid, accounts for 25% of gross weight; Organic solvent diesel oil accounts for 25% of gross weight.
This example is for Daqing crude oil, and treatment temp is 70 ℃, and adding dosage is 50ppm～100ppm, the condensation point of crude oil can be reduced to 14 ℃ by 33 ℃.For the Sudan's 1/2/4 crude oil, treatment temp is 105 ℃, and adding dosage is 50ppm～100ppm, the condensation point of crude oil can be reduced to 22 ℃ by 34 ℃.
Application conditions: can be with colloid in the crude oil, bitum alcohols normal temperature (condensation point that is higher than crude oil) or react in adding under the agent treatment temp of crude oil again arranged.
The form of product: product dissolves in alkane such as gasoline, diesel oil, sherwood oil etc., or is dissolved in aromatic hydrocarbon such as dimethylbenzene, heavy aromatics, C9 aromatic hydrocarbons, C10 aromatic hydrocarbons.
