Description
Technical field
The present invention relates to a kind of extraction and cleaning system, in particular to a kind of natural gas extraction and cleaning system.
Background technique
The natural gas gas in oil well is taken from before industrial use, needs to extract purified treatment, because containing
A large amount of moisture and oil evaporation gas and impurity.And it is domestic while focusing on plant energy consumption and processing cost at present, but neglect
It is low natural gas yield is omited, the problems such as key component purity is not high.
Summary of the invention
In order to solve the above technical problems, natural gas yield is high the present invention provides a kind of natural gas extraction and cleaning system, close
Key compositional purity is good.
In order to achieve the above objectives, the technical scheme is that a kind of natural gas extraction and cleaning system, including pre-separation
Device, gas-liquid separator, level-one gs-oil separator, second level gs-oil separator, compressor, supercharger, air cooler, evaporator, master are cold
Case, drying tower, threeway, dry gas air accumulator and natural gas air accumulator；Between preseparator and the left side air inlet of supercharger successively
It is connected with compressor, air cooler, gas-liquid separator and drying tower, the left side gas outlet of supercharger is cold with master after being connected with evaporator
The left side air inlet of case is connected, and the upper end air inlet of main ice chest is connected with the top gas outlet of second level gs-oil separator, main ice chest
Lower end gas outlet be connected with dry gas air accumulator, the right side gas outlet of main ice chest is connected with the air inlet of level-one gs-oil separator,
The top gas outlet of level-one gs-oil separator is connected with the right side inlets of supercharger, the right side gas outlet of supercharger and second level oil
The air inlet of gas separating device is connected, and the bottom end gas outlet of level-one gs-oil separator is connected with threeway, threeway all the way with second level oil gas
The bottom end gas outlet of separator is connected, and threeway another way is connected with natural gas air accumulator.
By using the present invention, the yield of natural gas is substantially increased, and key component purity is good, so that the matter of natural gas
Amount has very big promotion.
Detailed description of the invention
Fig. 1 is schematic diagram of the invention.
In figure: preseparator 1, gas-liquid separator 2, level-one gs-oil separator 31, second level gs-oil separator 32, compressor 4,
Supercharger 5, air cooler 6, evaporator 7, main ice chest 8, drying tower 9, threeway 10, dry gas air accumulator 11, natural gas air accumulator 12.
Specific embodiment
With reference to the accompanying drawing, and in conjunction with the embodiments, the present invention is described further.
Embodiment:
As shown in Figure 1, a kind of natural gas extraction and cleaning system, including preseparator 1, gas-liquid separator 2, level-one oil gas point
From device 31, second level gs-oil separator 32, compressor 4, supercharger 5, air cooler 6, evaporator 7, main ice chest 8, drying tower 9, threeway
10, dry gas air accumulator 11 and natural gas air accumulator 12；It is connected in turn between preseparator 1 and the left side air inlet of supercharger 5
Compressor 4, air cooler 6, gas-liquid separator 2 and drying tower 9, the left side gas outlet of supercharger 5 are cold with master after being connected with evaporator 7
The left side air inlet of case 8 is connected, and the upper end air inlet of main ice chest 8 is connected with the top gas outlet of second level gs-oil separator 32, main
The lower end gas outlet of ice chest 8 is connected with dry gas air accumulator 11, the right side gas outlet of main ice chest 8 and level-one gs-oil separator 31 into
Port is connected, and the top gas outlet of level-one gs-oil separator 31 is connected with the right side inlets of supercharger 5, the right side of supercharger 5
Gas outlet is connected with the air inlet of second level gs-oil separator 32, bottom end gas outlet and 10 phase of threeway of level-one gs-oil separator 31
Even, 10 1 tunnel of threeway is connected with the bottom end gas outlet of second level gs-oil separator 32,10 another way of threeway and natural gas air accumulator 12
It is connected.
The operation principle of the present invention is that: taking from the natural gas gas in oil well, first pre-separated device 1 isolates part water
Afterwards, pressure stabilizing is carried out into compressor 4, then cooling through air cooler 6, carries out gas-liquid separation into gas-liquid separator 2, separates
It after gas enters 9 drying and dehydrating of drying tower, is pressurized by supercharger 5, heat exchange, gas is then carried out by cryogen in evaporator 7
Temperature further decreases, after then exchanging heat in main ice chest 8 with the lean gas from 32 top of second level gs-oil separator, into one
Grade gs-oil separator 31, isolates natural gas from 31 bottom end of level-one gs-oil separator；The gas on 31 top of level-one gs-oil separator
Then enter second level gs-oil separator 32 after supercharger 5, isolates natural gas again, the natural gas separated is then by natural
Gas air accumulator 12 is uniformly collected storage.And lean gas is uniformly collected storage by dry gas air accumulator 11 as dry gas after exchanging heat
Hiding.
