Abstract
The invention discloses a kind of preparation method of the methane solvent with corrosion inhibition, using n-hexane, either light oil, normal heptane or naphtha, petroleum ether, direct steaming gasoline, imidazoline are prepared for a kind of methane solvent to this method for raw material.Methane solvent prepared by the method for the present invention is not only suitable for the liquid storage of methane, the storage of ethane propane is also applied for, storage efficiency, the safety and reliability for reducing storage expense, improving storage are improved so as to improve storage condition relative to CNG, LNG.
Description
Technical field
The invention belongs to energy storage technical fields, and in particular to a kind of preparation side of the methane solvent with corrosion inhibition
Method.
Background technology
It is that a kind of gaseous state exists under methane normal temperature and pressure, daily life and commercial Application are also had generally using pipeline
Part transport is using high pressure compressed and low-temperature liquefaction, difference abbreviation CNG and LNG.But above method there are problems that, mainly
It shows：
（1）, for CNG, under 200 atmospheric pressure, storage tank utilization rate is 22% under liquid, there are problems that inefficiency.
（2）, for CNG, due to being 200 atmospheric pressure, also there are problems that safety and storage tank heaviness.
（3）, for LNG, can be equivalent under room temperature 600 multi-party after the gasification of 1 side's liquid methane, efficiency is carried
Height, but there are tank structure complexity is of high cost.
（4）, -163 for LNGOBelow C could liquefy, it is necessary to and using special-purpose thermal insulation container, technical conditions are harsh, into
This is high.
Invention content
The present invention solves existing methane storage by providing a kind of preparation method of the methane solvent with corrosion inhibition
With the problem of CNG state efficiency is low, storage pressure is high and with LNG status techniques condition harshness, subzero less than 163 degree are needed
Row, it is expensive the problem of.
The technical solution adopted in the present invention is a kind of preparation method of the methane solvent with corrosion inhibition, this method
It is prepared according to following steps：
Preparation method
10-50 is followed successively by according to volume ratio:10-50:10-50:10-50:The ratio of 0.8-2.2 measures n-hexane or lightweight
Oil, normal heptane or naphtha, petroleum ether, direct steaming gasoline, imidazoline, are then sufficiently mixed, are stirred evenly, obtain this
Agent.
It is as a modification of the present invention scheme：30: 30: 30 are followed successively by according to volume ratio: 30:1.5 ratio measures
N-hexane either light oil, normal heptane or naphtha, petroleum ether, direct steaming gasoline, imidazoline, are then sufficiently mixed, are stirred
It mixes uniformly, obtains the agent.
In use, methane is dissolved in the methane solvent with corrosion inhibition of the method for the present invention preparation, then methane
Just exist with dissolved state, that is, liquid, amount of storage is improved with gaseous state storage than conventional methane, since methane is in solvent of the present invention
Solubility in liquid is proportionate with pressure, that is, pressure more high-dissolvability is bigger, is real under room temperature more specifically
The storage of methane liquid is showed, the prior art is could to realize that liquid is stored under extremely low temperature.Subzero 161.5 are wanted under normal pressure0Under C,
Methane can just become liquid.Usual LNG storage is in -161.5 degrees Celsius, the low-temperature storage tank of 0.1MPa or so.When
Preceding natural gas its main component is methane, is generally transported with special purpose ship or oil truck, and when use gasifies again.
The present invention is suitable for the storage under the room temperature lower pressure of methane, is also applied for the storage of ethane, propane, relative to
The storage of CNG, can double under equal pressure, volume, temperature more than amount of storage or equal amount of storage can be real
Now reduce the storage pressure of half.Which thereby enhance safety and storage efficiency.
During storage, comparison CNG is existed with high pressure compressed gas, and the methane solvent which makes is to make methane to dissolve
State（DNG）In the presence of, both methane and methane solvent for making of the present invention have chemical reaction after dissolving, just as white sugar with
It is the same that salt, which is dissolved in water, and due to the reduction of pressure during use, methane can be released.
