Embodiment 1
[0032] refer to figure 1 , the present invention is used for the pressurized recovery device of flash gas in sour gas field water, comprising:
[0033] Gas buffer tank 1, used for temporarily storing buffer flash gas;
[0034] The pressurization device 2, the inlet is connected with the gas buffer tank, and the outlet is connected with the raw gas pipeline 11, which is used to pressurize the flash gas;
[0035] Dehydration device, arranged between the gas buffer tank and the pressurization device, is used to remove the moisture in the flash gas;
[0036] The dehydration device includes at least one adsorption tower 3 .
[0037] The high-pressure sulfur-containing natural gas extracted from the wellhead of the present invention is subjected to gas-liquid separation through the separator, and the liquid part of the sulfur-containing gas field water is obtained after separation. The sulfur-containing gas field water is stored in the gas field water tank in the station, and the in...
Embodiment 2
[0041] refer to figure 1 , on the basis of Embodiment 1, this embodiment is also provided with a cold drying device arranged between the dehydration device and the gas buffer tank for removing moisture in the flash gas; the cold drying device includes an adsorption tower and a gas buffer tank The separator 6 and the cold dryer 5 between the tanks, the outlet of the gas buffer tank 1 is connected to the inlet of the adsorption tower 3 through the cold dryer 5 and the separator 6 in turn; the outlet temperature of the cold dryer is 4 ° C ~ 10 ℃. The cold dryer precipitates the moisture in the gas through the principle of cooling, and then separates the gas and liquid through the separator. The dehydration efficiency is high, but the precision is low; while the adsorption tower precipitates the moisture in the gas through the principle of adsorption, and the dehydration efficiency is low. But the precision is high. The gas can remove 70% to 80% of moisture through the cold drye...
Embodiment 3
[0043] refer to figure 1 , on the basis of Embodiment 1, this embodiment is also provided with a return device for returning the gas pressurized by the pressurization device to the gas buffer tank; The return pipe 7 between the booster device and the raw gas pipeline is provided with a check valve 8, and the return pipe is provided with a regulating valve 9 and a restrictor valve 10. When the inflow of water flash steam from a sour gas field decreases, the traditional method is to turn off the booster device, and then start the booster device again when the water flash gas inflow from the sour gas field is even, to pressurize and transport the flash gas. Such frequent start-ups Stopping the equipment will damage the equipment and reduce the service life of the equipment. For this reason, the present invention is equipped with a reflux device to return the flash gas to the buffer tank when the incoming flash gas is reduced, avoiding repeated startup and shutdown of the equipme...
