Description
Technical field
The invention belongs to petroleum gas technical fields, and in particular to a kind of methanol object coating and preparation method thereof.
Background technique
During oil-gas transportation, since there are aqueous hydrocarbon layer (from lower to upper) in conveyance conduit, in recovery process, pipe
There are certain pressure and temperatures in road, and when pressure and temperature reaches certain value, hydrate will shape during transportation
At, especially at pipeline turning and at gate valve, because pressure catastrophe characteristics caused by cool down, it is easier to lead to gas hydrate synthesis,
It is hindered oil-gas mining process, can seriously cause safety accident.
The method that tradition solves the problems, such as Hydrate Plugging mainly has physical method and chemical method, but has different defects.
Physical method includes: dehydration technique, pipeline heating technique, decompression control technology.
Dehydration technique: refer to by removing the moisture for causing hydrate to generate and eliminate the risk for generating hydrate, be mesh
The precautionary measures that preceding natural gas extraction generallys use.Dehydration can be absorbed using dry triol and molecular sieve adsorbs two kinds of sides
Method.Its shortcoming is that: dry triol evaporation is utilized, energy consumption is high for triethylene glycol. solution regenerative process, and solution can lose and pollute environment,
Dry triol is contacted with air can occur oxidation reaction, generate mordant organic acid corrosion pipeline；Using molecular sieve adsorption,
The adsorbent of drier lower layer needs to be replaced frequently, and regenerating molecular sieve is at energy consumption is high in the process.
Pipeline heating technique: refer to that the hydrate that by heating to pipeline system temperature can be higher than under system pressure is raw
At temperature, gas hydrates blocking pipeline is avoided.The law limitation is: being difficult to determine Hydrate Plugging position, heating process
In cause pressure to steeply rise due to decomposition of hydrate, cause line fracture, will cause production accident, lack safety.
It is depressured control technology: reducing line pressure, make its range under system temperature except hydrate generation, thus
Decompose hydrate.Have a disadvantage in that: in order to keep certain conveying that can see, power, the pressure of pipeline generally cannot be reduced arbitrarily, be deposited
In some potential safety problems, therefore the method has significant limitation.In addition, being absorbed big when pipeline decompression, decomposition of hydrate
The heat of amount, causes line temperature to reduce, and the water that decomposition of hydrate generates is easily converted to ice, it is more difficult to dissolve.
Chemical method includes: thermodynamic inhibitor method, anti polymerizer method, kinetic inhibitor method.
Thermodynamics presses down agent method: being directed to that the very low alcohols material of freezing point is added in natural gas runner, makes the flat of hydrate
Weighing apparatus generates the operation temperature that pressure is higher than the operating pressure of pipeline or the balance generation temperature of hydrate is lower than pipeline, to keep away
Exempt from the generation of hydrate.Its defect essentially consists in: it is a large amount of that alcohols material recycling difficulty, and remaining alcohols material meeting is added
Huge pollution is caused to environment.
Anti polymerizer method: the effect of anti polymerizer is by preventing hydrate crystal particle aggregation blocking, to make in pipeline
Hydrate fluid will not be assembled, fluidly as pipeline flows.In fact, anti polymerizer is a kind of typical ionic table
Face activating agent has diethanol amine, ethoxyquin amine surfactants with most typical anti polymerizer at present；Quaternary ammonium salt surface is living
Property agent；Caprolactam class surfactant；Alkylamide surfactant etc..This kind of anti polymerizer can equally bring huge to environment
Big pollution.
Kinetic inhibitor method: kinetic inhibitor main function is that hydrate is hindered to generate, and it is dynamic to change hydrate growth
Mechanics has environment friendly.Since the 1990s, kinetic inhibitor is rapidly developed.With polyethylene
Pyrrolidones (PVP) is that the kinetic inhibition of representative is applied in Tetrahydrofuran hydrate inhibition first, can be prolonged
The growth of slow Tetrahydrofuran hydrate and assemble index.Subsequent researcher starts based on PVP, synthesizes a series of polymer,
Wherein it be no lack of the product better than PVP effect, new platform has been climbed up in the development if the successful research and development of PVCap are kinetic inhibitor
Rank.In addition, some natural products are also found to be with kinetic inhibition effect, such as biological antifreeze (AFPs), tapioca,
Fructose, amino acid etc..Although kinetic inhibition has, dosage is few, advantages of environment protection, because it is relatively low with inhibitory activity,
Poor universality, vulnerable to limitations such as environmental restrictions, in actual production application cannot promote.
In conclusion there is unworthiness, environmental pollution in view of physical method and chemical method and lack the drawbacks such as safety.Cause
This, developing a kind of methanol object space method for solving above-mentioned drawback is very important.Polytetrafluoroethylene (PTFE) that the present invention utilizes, polyphenyl
Thioether and hydrophobic fumed silica raw material have the characteristics that strong corrosion resistant, high temperature resistant and low temperature, and applicability is fabulous, and coating
It not can cause environmental pollution, the threat of the more not no secure context of the coating made.
According to existing research, the necessary condition of Hydrate Plugging pipeline has following two points: hydrate can be nucleated in pipeline
And it grows；Hydrate particle is deposited and is adhered on tube wall.The present invention is asked for Hydrate Plugging pipe-line and equipment
