Abstract
The invention discloses a high-flash-point waxing agent and a preparation method thereof. The high-flash-point waxing agent has the advantages of high flash point and high safety. The high-flash-point waxing agent is prepared from the following raw materials in percentage by weight: 70-90% of C12-C16 alkane and 10-30% of surfactant. The preparation technique disclosed by the invention is simple and convenient to use, and changes the wax crystal structure in crude oil, so that the wax crystal is in the dispersed state and is suspended in the crude oil, thereby avoiding fire hazard and other potential safety hazards and having favorable application prospects.
Description
Technical field
The present invention relates to clean-out system technical field, particularly relate to a kind of high flash point parent cerate and preparation method thereof.
Background technology
Oil field is before exploitation, and crude oil, under high temperature, condition of high voltage, generally all exists with single-phase liquid, and wax is dissolved in crude oil completely.In the time that develop in oil field, crude oil flows into shaft bottom from oil bearing reservoir, then from shaft bottom along wellbore lift to wellhead pressure, temperature declines thereupon, when pressure decreased is to a certain extent time, destroyed paraffin and has been dissolved in the equilibrium conditions in crude oil, causes wax crystal to be separated out.When the temperature of crude oil drops to the temperature (wax precipitation piont) that wax crystalline substance starts to separate out, the brilliant particulate of wax just starts to separate out on oil stream and tube wall.Along with the further reduction of temperature, pressure, paraffin will constantly be separated out, and its xln is just assembled and is deposited on the tubing such as oil pipe, sleeve pipe, sucker rod, oil well pump and equipment.The brilliant part of wax in oil stream is with the extraction of oil stream, and the metallic surface of oil well installation is assembled, condenses and adhered to a part.When wax deposition is serious, oil pipeline can be stopped up completely, cause stopping production.Therefore,, during oil production, for the best is produced, in cleaning and elimination processing unit, flow line, oil well casing and storage tank, wax crystalline substance is extremely important.Traditional low-flash mixture of the common use of cleaning, mostly is aromatic series or halohydrocarbon mixes.For example trimethylbenzene, ethylbenzene, isopropyl benzene, this type of raw material flash-point is extremely low, and equipment is fire-prone in high speed rotating process, has serious potential safety hazard.
Summary of the invention
Based on this, be necessary the problem for the shortcoming of prior art, a kind of high flash point parent cerate and preparation method thereof is provided, flash-point is high, security good, and cost of manufacture is low, and preparation technology is simple, easy to use.
A kind of high flash point parent cerate and preparation method thereof, described high flash point parent cerate is made up of the raw material of following weight per-cent:
C12-C16 alkanes 70 ~ 90%;
Tensio-active agent 10 ~ 30%;
The percentage ratio sum of each component content is 100% above.
In an embodiment, described alkanes is isomery n-Hexadecane therein.
In an embodiment, described tensio-active agent is alkylphenol polyoxyethylene therein.
In an embodiment, described preparation method comprises following preparation process therein:
1., get the raw materials ready: described C12-C16 alkanes and tensio-active agent are weighed according to described weight percent, with for subsequent use;
2., mix: C12-C16 alkanes and tensio-active agent that step is weighed in 1. mix in mixing vessel;
3., stir: start to be uniformly mixed C12-C16 alkanes and tensio-active agent in container, until described C12-C16 alkanes and tensio-active agent fully mix, obtain described high flash point parent cerate.
Above-mentioned high flash point parent cerate and preparation method thereof, this parent's cerate flash-point is high, security good, and easy to use, efficient, its preparation method is simple.According to the similar principle that mixes, in crude oil, add this parent's cerate, just change the wax-crystal structure in crude oil, make wax crystalline substance in dispersion state, be suspended in crude oil.Because its flash-point is higher, avoid occurring the potential safety hazards such as fire, have a good application prospect.
