Description
Technical field
The invention belongs to field of oilfield chemistry, and in particular to a kind of novel normal-temperature efficient sulphur solvent and preparation method thereof.
Background technology
The unconventional acid gas reservoir of a batch has now been found both at home and abroad, such gas reservoir in the process of development, can generate one kind
Harmful substance is called elementary sulfur (i.e. S8).With the change of environmental condition, elementary sulfur will in the form of sulphur crystalline solid, from
It condensation and is deposited in air-flow.Easily deposition causes sulphur to block to elementary sulfur in payzone, pit shaft and gathering system, especially causes
The blocking of gas transmission line brings great harm to the exploitation of such gas reservoir, this problem in the exploitation of acid gas reservoir urgently
It is to be solved.So it is to solve the problems, such as this fabulous selection to develop efficient sulphur solvent.
Since the eighties, the research to sulphur solvent has been begun to both at home and abroad, wherein external mainly with Canadian, the U.S.
DMDS (dimethyl disulfide) sulfur solvent systems are representative, and early 20th century, domestic Li Li, Liu Jianyi et al. carries out the system
Further research obtains the DMDS sulfur solvent systems of higher performance, but DMDS is expensive, high volatility, irritant
Foul odour, strong toxicity.
CS without DMDS2(carbon disulfide) although molten sulphur effect is fine, its is toxic, burning point is low, explosive, seldom makes
With although other amines, benzene series class and alcohols sulphur solvent also have certain molten sulphur ability, the sulfur solubility at 30 DEG C
No more than 30%, and molten sulphur speed is slow, dosage is big, and relative cost is high.
Sulfur solubility of the best DMDS systems of generally acknowledged sulfur solubility at 25 DEG C is 173.6% at present, at 90 DEG C
Sulfur solubility for 610.9%, but not only irritant stench, toxicity are big, stability is poor, and expensive, sexual valence by DMDS
Than low.
2008, triethylene tetramine, ethanol amine, ethylene glycol were carried out 2 by Liu Jingcheng et al.:2:1 compounding, complex solvent have
Higher sulfur solubility, sulphur solution rate is also very fast, but the system corrosivity is stronger.
Huang Xue pine et al. developed a kind of ordorless, small toxicity suitable for high sulfur Gas Fields in 2013, without strong thorn
Swash the sulphur solvent of property smell, which is compounded by diethylenetriamine, DMF (dimethylformamide), although the system ratio
Liu Jing into et al. exploitation triethylene tetramine system sulfur solubility and molten sulphur speed it is all high, but sulfur solubility only has 40.25%
~49.90%, sulfur solubility still cannot meet actual requirement, and triethylene tetramine and diethylenetriamine have very strong corruption
Corrosion is serious to pipeline corrosion.
Invention content
The present invention in view of the above problems, develop new normal-temperature efficient, low-corrosiveness amine sulphur solvent and
A kind of new and effective sulphur solvent and preparation method thereof is provided, this sulphur solvent is ordorless, at low cost, non-corrosive, sulfur solubility
Height, solution rate is fast and room temperature is easy to operate.
The present invention adopts the following technical scheme that：
The present invention provides a kind of new and effective sulphur solvent, by the material composition of following mass parts：
50-80 parts of main solvent；
1-5 parts of catalyst；
1-5 parts of co-catalyst.
The main solvent for ethamine, n-propylamine, isopropylamine, n-butylamine, isobutyl amine, tert-butylamine, aniline, benzylamine, alpha-naphthylamine,
The mixture of one or more of beta-naphthylamine.
The catalyst is the mixture of one or both of NaHS, potassium bisulfide.
The co-catalyst is mainly the mixture of one or more of pyridine, piperidines, pyrimidine, quinoline, isoquinolin, institute
The big pi bond structure that stating co-catalyst has can interact with S8 rings, it is promoted to be dissolved by host agent.
The present invention also provides a kind of methods for preparing the sulphur solvent, include the following steps：
(1) a certain amount of main solvent is added in into reaction vessel in ventilation；
(2) catalyst (the 1.0% of main solvent quality) is added in, is stirred；
(3) co-catalyst (the 2.0% of main solvent quality) is added in, stirs to obtain normal-temperature efficient sulphur solvent.
Beneficial effects of the present invention：
(1) amine solvent used in the system is not only without corrosivity, also with certain antisepsis, and without evil
It is smelly, at low cost, sulfur solubility is high, solution rate is fast；
(2) system is compounded by amine solvent and a kind of catalyst, a kind of co-catalyst, sulfur solubility considerably beyond
The conventional sulphur solvent for being free of DMDS, under normal temperature condition, sulfur solubility can reach more than 80%, i.e. 1g solvents can dissolve 0.8g
Above sulphur reaches 1.6 times or more of the sulphur solvent sulphur solvability without DMDS at present；
(3) the big pi bond structure that co-catalyst has can and S8Ring interacts, and makes the sulphur solution rate of the system significantly
It improves, the sulphur solution rate of unit solvent can reach 0.78g/min, overcome conventional without DMDS sulphur solvent sulphur solution rates
The shortcomings that slow.
