Abstract
A low-pressure flash evaporation separation device for gas field sewage containing dissolved gas is applied for the technical field of sewage collection, conveying and separation of oil and gas field. A sewage inlet of a double-cylinder horizontal gravity separator is connected with a sewage discharging main pipe. A gas outlet of the double-cylinder horizontal gravity separator is connected with a decompression valve. The other end of the pressure reduction valve is provided with a pipe which is connected with a torch. A liquid outlet of the double-cylinder horizontal gravity separator is connected with an electric liquid discharging valve through pipeline. Pipeline is also connected between an outlet of the electric liquid discharging valve and an embedded sewage tank. The low-pressure flash evaporation separation device for gas field sewage containing dissolved gas has the following effects: separating the gas which is dissolved in stratum water; performing combustion treatment for flashed vapor; effectively settling a problem of environment pollution caused by entering of the poisonous and harmful gas into atmosphere after volatilization; and preventing a pressure increase phenomenon of a sewage tank.
Description
Technical field
The utility model relates to oil gas field mining site gathering-transferring technology field, is a kind of minimizing noxious gas emission, and that reduces environmental pollution contains solution gas gas field sewage low pressure flash separator.
Background technology
At present, in the collection production process of natural gas, the formation water of gas well output is dissolved with natural gas, H in (back claims sewage)
2S, CO
2Deng gas.High-pressure natural gas enters the gravity horizontal separator through the heating throttling to 5MPa, with free water separation and gathering and hydrops bag from natural gas, directly enter buried sewage jar then.In the sewage jar, because sewage enters atmospheric pressure environment (the sewage jar links to each other with atmosphere) from hyperbaric environment, the gas that is dissolved in the sewage is overflowed again.The continuous blowdown escaping gas accumulates in the sewage jar, and part diffuses in the gas gathering station.When sewage jar breather valve stops up, Volatile Gas can't be discharged to be gathered in and be caused the generation of suppressing contingencies such as jar when jar interior easily.Simultaneously, owing to contain H in the Volatile Gas
2Toxic and harmfuls such as S after Volatile Gas enters atmosphere, cause that gas gathering station sewage jar ambient air is of poor quality, the smell is awful, and environment is polluted, and also the employee of gas gathering station caused certain injury.
Carry out special research at above-mentioned existing problems, utility model contain solution gas sewage low pressure flash technology, play the purpose of flash distillation solubilised state gas, make the gas that discharges in the sewage pass through torch burning, effectively eliminated the sewage jar phenomenon that builds the pressure, purify local environment, guaranteed the safety in production of gas gathering station.
The utility model content
The purpose of this utility model is: a kind of solution gas gas field sewage low pressure flash separator that contains is provided, pass through low pressure flash, the toxic and harmful that is dissolved in the sewage is discharged concentrate the processing of burning, effectively eliminate the sewage jar phenomenon that builds the pressure, prevent the pollution of the environment, guarantee the personnel health, guarantee the gas gathering station safety in production.
The technical solution adopted in the utility model is: contain solution gas gas field sewage low pressure flash separator, mainly be made up of the horizontal gravity separator of the bitubular, pressure-reducing valve, electronic tapping valve, safety valve and sewage jar.It is characterized in that: the sewage import of the horizontal gravity separator of the bitubular connects blowdown main, and the gas vent of the horizontal gravity separator of the bitubular connects pressure-reducing valve, and the other end of pressure-reducing valve has pipeline to connect torch; The liquid outlet of the horizontal gravity separator of the bitubular connects electronic tapping valve by pipeline, is connected with pipeline between electronic tapping valve outlet and the buried sewage jar.
For easy to maintenance, on the pipeline of the two ends of electronic tapping valve, be fixed with a valve respectively, and, valve arranged on the bypass line on the pipeline bypass line being arranged between horizontal gravity separator of the bitubular and the buried sewage jar, bypass line is in parallel with electronic tapping valve.
The beneficial effects of the utility model: the utility model contains solution gas gas field sewage low pressure flash separator, the gas that is dissolved in the formation water can be separated; To the flashed vapour processing of burning, enter the atmosphere pollution problem of environment after efficiently solving the toxic and harmful volatilization; Prevent that the sewage jar from suppressing the generation of jar phenomenon.
Description of drawings
Fig. 1 is that the utility model contains solution gas gas field sewage low pressure flash separator structural representation.
Among the figure, 1-gas-liquid separator, 2-pressure-reducing valve, the electronic tapping valve of 3-, 4-safety valve, 5-blowdown main, 6-sewage jar.
The specific embodiment
Embodiment 1: containing solution gas gas field sewage low pressure flash separator with one is example, and the utility model is described in further detail.
Consult Fig. 1.The utility model contains solution gas gas field sewage low pressure flash separator, mainly is made up of the horizontal gravity separator 1 of the bitubular, pressure-reducing valve 2, electronic tapping valve 3, safety valve 4 and sewage jar 6.The sewage import of the horizontal gravity separator 1 of the bitubular connects blowdown main 5, and the gas vent of the horizontal gravity separator 1 of the bitubular connects pressure-reducing valve 2, and the other end of pressure-reducing valve 2 has pipeline to connect torch; The liquid outlet of the horizontal gravity separator 1 of the bitubular connects electronic tapping valve 3 by pipeline, is connected with pipeline between electronic tapping valve 3 outlets and the buried sewage jar 6.The model of electronic tapping valve 3 is: 11-ld.Be fixed with a valve respectively on the pipeline of the two ends of electronic tapping valve 3, and on the pipeline bypass line being arranged between horizontal gravity separator 1 of the bitubular and the buried sewage jar 6, valve arranged on the bypass line, bypass line is in parallel with electronic tapping valve 3.
The use that contains solution gas gas field sewage low pressure flash separator is: utilize the horizontal gravity separator 1 of the bitubular as the low pressure flash separator, blowdown main 5 compiles the gas field sewage that comes and enters flash distillation in the horizontal gravity separator 1 of the bitubular, behind low pressure flash, the gas that flashes off enters the torch processing of burning after by one-level pressure-reducing valve 2, and the sewage that does not contain solution gas then enters sewage jar 6 by electronic tapping valve 3.
The horizontal gravity separator 1 of the bitubular is consulted periodical: " petrochemical industry application "; 2009 28 4 phases of volume, author Han Qianghui etc.
