Abstract
The invention relates to a reaction type crude oil flow modifier containing an amine organic polymer. Relates to the technical field of general chemical methods, preparation of organic macromolecular compounds and pipeline systems. The water-soluble organic acid detergent consists of an amine-containing organic polymer, a surfactant and a micromolecular organic matter, wherein the proportion of each component in the total weight of 100 percent is as follows: 4 to 28 percent of organic polymer containing amine, 5 to 35 percent of surfactant and 20 to 70 percent of micromolecular organic matter. It can react with polar groups of colloid and asphaltene in crude oil, such as alcohol, amine, carboxylic acid, etc. Therefore, the invention has obvious pour point depression and fluidity improvement on the crude oil.
Description
Technical field
The present invention is a kind of amine organic macromolecule reaction type crude oil flow modifying agent that contains.The preparation and the tubing system technical field that relate to general chemical process, organic macromolecule compound.
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 amine 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 amine, tensio-active agent and small organic molecule, is that the ratio of each component in 100% is: the organic polymer 4%～28%, tensio-active agent 5%～35% and the small organic molecule 20%～70% that contain amine in gross weight.
Wherein:
The organic polymer that contains amine is to carry out polymerization with monomers such as alkene, acrylate, ethylene vinyl acetate, styrene-acrylonitrile copolymer acid amides, vinyl cyanide and, maleic anhydride (maleic acid) monomer to form binary, ternary or tetrapolymer, carry out derivatize with aliphatic diamine then, form the high molecular polymer that contains amine on the side chain.Or-polymer homopolymer or the multipolymer of N=N-NHR, R is alkane (C2～C35) and aromatic hydrocarbon (C2～C35);
Small organic molecule is selected from aliphatic amide, as aliphatic amide, octylame, lauryl amine, coconut (oil) amine, stearylamine, beef tallow amine etc., and aliphatic diamine, diethanolamine, Yi Bingchunan mixture, or alkyl benzene amine etc.;
Organic solvent is selected from: the gasoline of alkane, diesel oil, sherwood oil etc., or the dimethylbenzene of aromatic hydrocarbon, 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. the organic polymer that contains amine is to carry out polymerization with ethylene vinyl acetate monomer and maleic anhydride (maleic acid) monomer to form binary, ternary or tetrapolymer, carry out derivatize with aliphatic diamine then, form the high molecular polymer that contains amine on the side chain; In gross weight is in 100%, forms the organic polymer that contains amine and accounts for 16%; The small organic molecule aliphatic amide accounts for 24%; The organic solvent sherwood oil accounts for 60%.
This crude oil flow properties-correcting agent is used for Kazakhstan's crude oil, and treatment temp is 70 ℃, and adding dosage is 50ppm～100ppm, the condensation point of crude oil can be reduced to-8 ℃ by 16 ℃.For Daqing crude oil, treatment temp is 70 ℃, and adding dosage is 50ppm～100ppm, the condensation point of crude oil can be reduced to 14 ℃ by 33 ℃.
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.
