The technical effect and its realization process for the essence that art scheme is played are as follows: the groove makes the fixation of coil pipe more square
Just, safer, directly place.
TEG dehydration device, which is characterized in that natural gas line is connected to absorption tower, and pipeline point is stretched out on the absorption tower
Other connecting sleeve heat exchanger and air accumulator, the air accumulator are ined succession a separator by pipeline, and the separator stretches out pipeline
It respectively is passed through reboiler and burner, the reboiler and rich solution rectifying column are arranged together, the rich solution rectifying column protruded tube
Road connects flash vessel, and the flash vessel stretches out pipeline and connects flash separator, and the pipeline that the flash separator stretches out accesses combustion
Burner.
The realization process that the technical solution at this place is played is as follows: main flow:
A. wet gas by feed gas separator separate 5 μm or more drop and solid (guarantee device operation when not
Salt crust blocking pipe valve instrument can occur) afterwards into the gas-liquid separation chamber of absorption tower lower part, it separates because filter separator is in thing
Therefore state and possibly into the free fluid in absorption tower.
Wet gas, by packing layer, fills in the uphill process in absorption tower with the poor triethylene glycol entered from tower top
Tap touching, gas-liquid mass transfer exchange after the moisture in natural gas is fallen in removing, catch the glycol liquid that the removing of mist silk screen is greater than 5 μm through tower top
Tower is gone out by top of tower after drop.
B. it after dry gas goes out tower, exchanges heat by bushing type gas-liquid heat-exchange with into the poor glycol of heat before tower, it is sweet to reduce poor three
Alcohol inlet temperature of stabilizer, the product gas after heat exchange adjust control absorption tower operating pressure through field mounted self-operated type pneumatic diaphragm control valve,
Subsequently into outer gas line network.
C. poor triethylene glycol enters absorption tower by tower top, from top to bottom passes through filler tower tray, absorbs the moisture in natural gas.
Absorb moisture rich glycol and partial high pressure natural gas gas-liquid mixture by filter enter KIMRAY pump (glycol and naturally
Gas transfer tube).
D. rich glycol, which goes out KIMRAY and pumps into triethylene glycol, regenerates column overhead coil pipe, by overhead vapours be heated to 40~60 DEG C it is laggard
Enter flash tank, the appropriate hydrocarbon gas that flash separation goes out the power gas as driving KIMRAY pump and is dissolved in glycol.Regenerate column overhead
Coil pipe both ends are connected with bypass regulator valve, to adjust rich glycol into coil pipe flow, thus adjust regeneration column overhead reflux
Amount.
E. glycol is flowed out by flash tank lower part, sequentially enters filter-cloth filtering separator and active carbon filter.Pass through filter cloth
Filter filters out 5 μm or more in rich glycol of solid impurity.The portion in rich glycol solution is filtered out by active carbon filter
Degradation material when heavy hydrocarbon and triethylene glycol being divided to regenerate.Two filters are equipped with bypass line.In filter replacement filter core, dress
Setting can be continued to run by bypass line.
F. rich glycol enters the poor rich liquid heat exchanger that type selecting is plate heat exchanger after filtering, and by regeneration reboiler lower part
The poor glycol heat exchange of the heat of triethylene glycol surge tank outflow enters triethylene glycol regenerator after being warming up to 140 DEG C~170 DEG C.
G. in triethylene glycol regenerator, by the comprehensive function of stripping section, rectifying section, overhead reflux and tower bottom reboiling, make
Moisture and very little some hydrocarbon in rich glycol isolate tower.Tower bottom reboiling temperature is 196 DEG C -198 DEG C, triethylene glycol weight percent
Specific concentration is up to 98.8~99.2%.
H. the poor glycol in reboiler is through lean solution stripping columns, and overflow is to reboiler lower part triethylene glycol surge tank, in lean solution vapour
Lean solution can be stripped by the hot drying gas of introducing stripping columns lower part by mentioning in column, and the poor glycol weight percent after stripping is dense
Degree is up to 99.8%.
I. lean solution is exchanged heat in surge tank by heat exchange coil and rich glycol, and by the cooling of buffering tank wall, temperature
It is down to 160 DEG C or so and goes out surge tank, into board-like poor rich liquid heat exchanger, exchange heat with rich glycol, temperature is down to 60 DEG C or less into suction
Receive the moisture in tower absorption natural gas.
The reboiler connects heat exchange tank by air lift column.The heat exchange tank stretches out pipeline and connects rich or poor liquid plate heat exchange
Device, flash tank lower section stretching pipeline access rich solution plate heat exchanger by pipeline after connecting filter and can be with the interior objects out of heat exchange tank
It exchanges heat.The heat exchange tank stretches out pipeline access after pipeline connects rich or poor liquid plate heat exchanger and opens Mir's pump, then access set
Heat exchange of heat pipe.Pipeline is stretched out below the flash tank by being passed through rich solution rectifying column after rich or poor liquid plate heat exchanger.The absorption
Tower directly stretches out pipeline by being passed through rich solution rectifying column after opening Mir's pump.The filter is concatenated active carbon filter and filter
Cloth filter.
The realization process that the technical solution at this place is played is as follows: assisting workflows:
A. one dry gas is drawn to triethylene glycol surge tank, through Self-operated pressure after heating from absorption tower outlet dry gas main pipe
Regulating valve throttling and pressure stabilizing enter fuel gas surge tank to 0.05MPa.
One gas is drawn from fuel gas surge tank, makees fuel gas into triethylene glycol regeneration reboiler burner.From fuel gas
Surge tank draws another strand of gas, and triethylene glycol is entered after flowmeter and regenerates reboiler, is extended after heating to lean solution stripping columns lower part,
As lean solution stripping gas.
B. fuel gas is drawn with fuel gas surge tank after triethylene glycol rich solution flash drum overhead vapor is drawn to converge, and makees reboiling
Device burner fuel gas.
It c. is largely vapor from the gas that triethylene glycol regeneration column overhead excludes, lime set enters sewage collecting tank, no
Solidifying gas scene emptying.
D. overpressure relief
Absorption tower sets superpressure blowdown system；
Flash tank and fuel gas surge tank setting superpressure safety relief system simultaneously introduce flare system；
E. absorption tower, flash tank, mechanical filter, active carbon filter, triethylene glycol regenerate reboiler, triethylene glycol surge tank
Bottom is equipped with sewage draining exit.Each container sewage foul water system in standing by concatenated two Valved discharges.
F.KIMRAY pump discharge pipeline is equipped with a multiple line and is connected with rich glycol into triethylene glycol regenerator pipeline, throws for device
It is used when triethylene glycol is perfused when production into reboiler.
G. instrument wind is introduced by yard air feed system, goes to use everywhere after depressurizing in sledge.
In a creative way, above each effect is individually present, moreover it is possible to the combination of the above results is completed with a nested structure.
It is clear that the technical effect that the above structure is realized is realized, if the additional technical solution is not taken into account, this patent title is also
It can be a kind of drying structure.Part details is not shown in the figure.
It should be noted that multiple schemes that this patent provides include the basic scheme of itself, independently of each other, not mutually
It restricts, but it can also be combined with each other in the absence of conflict, reach multiple effects and realize jointly.
Basic principles, main features, and advantages of the present invention has been shown and described above.Ability
The technical staff in domain should be recognized that the present utility model is not limited to the above embodiments, described in the above embodiment and specification
Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model can also
