The water diversion separator consists of spherical seals, a tank body, a TP plate unit, a screen foam remover, a sleeve, an anti-eddy baffle which are arranged in the tank body, and an air inlet and an air outlet of the tank body, wherein the tank body of the separator is a horizontal circular tank and is provided with the spherical seals at both ends in a welding manner, a nickel-base alloy layer is overlaid on the inner wall of the tank body. The water diversion separator disclosed by the utility model has an excellent corrosion resistant effect on high pressure and high concentration hydrogen sulfide moisture and acidic liquids and can be used as a gas-liquid-solid separation device of natural gas containing high content of hydrogen sulfide and carbon dioxide. Meanwhile, solid sediments at the bottom of the separator can be further cleaned according to production requirements.
Description
Technical field
The utility model relates to the unstripped gas separation technology field of high sulfuric acid gas field gas gathering station field, be particularly related to minute separator of a kind of anti-H 2 S, antiacid corrosion and resistance against sulfide stress cracking, resistance against hydrogen cracking, be applicable to the surface separation work of the row's of returning well after high-hydrogen sulfide Oil/gas Well, acid fracturing, belong to a kind of separation equipment of gathering and transportation technology technical field.
Background technology
Dividing separator is one of equipment the most frequently used in oil field development production process.Its operation principle is: oil gas aqueous mixtures enters at a high speed pre-degas chamber, by cyclonic separation or Action of Gravity Field, deviate from a large amount of accompanying gas with crude oil, oil water mixture after pre-degassed enters at a high speed distributor and washing chamber through mozzle, at the active water layer wash-in that contains demulsifier, wash breakdown of emulsion, carry out current stabilization, reduce the Reynolds number that carrys out liquid, again after coalescent rectification, flow into the further sedimentation separation in sedimentation separation chamber, degassed crude climbs over dividing plate and enters grease chamber, and flow out separator after flowmeter metering, water depended on pressure balance enters hydroecium through conduit, thereby reach the object of oil gas water three phase separation.
At present very ripe from the three phase separator structure of external import, and all there are different pluses and minuses from manufacture method in the method for designing of various separators, adapts to different working environments.Horizontal gravity separator is to utilize Action of Gravity Field to make drop separated from air-flow.Air-flow enters after separator, its end produce impact and make a large amount of carry liquid separated under.Along with deepening continuously of high sulfur-bearing gas reservoir exploration and development, for the separator designs of high-hydrogen sulfide and carbon dioxide sour natural gas and application, more severe anticorrosive problem will be faced.The acid gas such as high-hydrogen sulfide and carbon dioxide in the gas reservoir of northeast, river, H
2s average content 15.16%, CO
2average content 8.64%, raw natural gas has extremely strong corrosivity, and the safe operation of gathering system is formed and had a strong impact on.The import that domestic high sulfur Gas Fields adopts divides separator to use SA-516 steel as separator inner-wall material, and in process of production, through above operation in a year, the corrosion dell that 1mm does not wait to 5mm, the safety of field, serious threat station all appearred in tank base.The conventional method that solves separator etching problem has two kinds: the one, and the method for employing inner wall anti-corrosive erosion resisting coating, isolation inwall contacts with corrosion gas-liquid, but undercoating preparation technology is more complicated, in use also easily occur the situations such as cracking comes off causing more serious local corrosion; The 2nd, separator is thickeied, improve the corrosion allowance of inwall, but can increase manufacturing cost, be not easy to the layout of the inner structure parts such as by-pass valve control, baffle plate simultaneously, this mode can only extend the service life of separator, can not fundamentally solve etching problem.
Utility model content
The purpose of this utility model is to overcome the serious defect of separator etching problem that above-mentioned prior art exists, and minute separator of the antiacid corrosion of a kind of anti-H 2 S is provided.
The utility model is comprised of air inlet, the gas outlet on TP plate group, wire mesh demister, sleeve, anti-swirl baffle and tank body in dome head, tank body and tank body, separator tank body adopts horizontal round can and welds with dome head at two ends, and in inner tank wall, heap is welded with nickel base alloy layer.
The bottom position of described tank body cavity is provided with sand washing group pipe, and the bottom of sand washing group pipe has sand washing port, on the bottom outer tube wall of tank body, has sand washing and sewage draining exit.
Knockout drum inner wall overlaying one deck nickel base alloy layer of the present utility model, the hydrogen sulfide moisture of high pressure, high concentration and acid solution are all had to good anticorrosive effect, can be used as the gas-liquid-solid separator of high-hydrogen sulfide, carbon dioxide natural gas, can also carry out according to Production requirement the cleaning of separator bottom solid deposits simultaneously.
Accompanying drawing explanation
The structural representation of minute separator of the antiacid corrosion of Fig. 1 the utility model anti-H 2 S.
The specific embodiment
As shown in Figure 1, the utility model is comprised of air inlet 2, the gas outlet 4 on TP plate group 5, wire mesh demister 8, sleeve 9, anti-swirl baffle 11 and tank body 6 in dome head 1,10, tank body 6 and tank body 6, separator tank body adopts horizontal round can and welds with dome head 1,10 at two ends, and on tank body 6 inwalls, heap is welded with nickel base alloy layer 7.
The bottom position of described tank body 6 cavitys is provided with sand washing group pipe 13, and the bottom of sand washing group pipe 13 has sand washing port, has sand washing port 14 and sewage draining exit 12 on the bottom outer tube wall of tank body 6.
The sand washing port of described sand washing group pipe 13 bottoms is radial.
The import department of described tank body 6 is welded with " L " shape cushioning fender 3, can reduce the solid particle and the erosion of liquid to tank body 6 inside that in unstripped gas, mix.
By the air inlet 2 on tank body 6 of the present utility model and gas outlet 4, the utility model is connected on gathering line, the air inlet 2 of unstripped gas on tank body 6 enters in the cavity of tank body 6 and carries out gas-liquid separation, gas after separation is discharged by the gas outlet on tank body 6, liquid is discharged by the sewage draining exit 12 of tank body 6 bottoms, the nickel base alloy layer 7 of built-up welding on tank body 6 inwalls, can significantly reduce the corrosion rate of tank body 6 inwalls, improve the service life of minute separator.
