Abstract
The invention discloses an alkylene oxide-containing organic macromolecule reaction type crude oil flow modifying agent which relates to the technical field of a common chemical method, preparation of organic macromolecule compounds and a pipeline system. The alkylene oxide-containing organic macromolecule reaction type crude oil flow modifying agent comprises the following components in 100 percent of total weight: 2-27 percent of alkylene oxide-containing organic macromolecule, 5-28 percent of surface active agent and 10-80 percent of micromolecule organic matter. The modifying agent can react with polar groups, such as alcohol, amine, carboxylic acid, and the like of colloid and asphaltene in crude oil. Accordingly, 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 oxirane 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 oxirane 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 oxirane, tensio-active agent and small organic molecule, is that the ratio of each component in 100% is: the organic polymer 2%～27%, tensio-active agent 5%～28% and the small organic molecule 10%～80% that contain oxirane in gross weight.
Wherein:
The organic polymer that contains oxirane is the high molecular polymer that contains oxirane on side chain;
Tensio-active agent is selected from two hard esteramides ethyl epoxypropyl aliquats, alkylamino ethyl imidazol(e) hyamine, two hard esteramides ethyl epoxypropyl amine ureas etc.;
Small organic molecule is selected from the compound that contains oxirane, as bisphenol A epoxide resin, novolac epoxy;
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. in gross weight is that the ratio of each component in 100% is: the organic polymer that contains oxirane is the high molecular polymer that contains oxirane on side chain, accounts for 12%; The two hard esteramides ethyl epoxypropyl amine ureas of tensio-active agent choosing account for 22%; The small organic molecule choosing contains compound--the novolac epoxy of oxirane, accounts for 36%; Organic solvent dimethylbenzene accounts for 30%.
This example is 70 ℃ through on probation to Daqing crude oil in treatment temp, and adding dosage is under the 56ppm condition, 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.
