Description

TECHNICAL FIELD

[0001] The utility model relates to the field of oil associated gas purification, especially relates to a drying and cooling device for oilfield associated gas. BACKGROUND

[0002] At present, the important use of oilfield associated gas in oilfield is as fuel of heating furnace. The associated gas is mixed gas, usually mainly containing methane, and also containing a small amount of non-hydrocarbon gas, oil, water and other impurities. In order to avoid the problems that the associated gas has high temperature and poor gas-liquid separation effect, and then causes the heating furnace to appear the phenomenon of flameout, and the pipeline or drain is prone to freeze in winter, and the normal use of the burner is affected, it is necessary to process it through the drying and cooling device;

[0003] When the existing drying and cooling device for oilfield associated gas is used, the clean water enters the inner pipe from the upper water inlet pipe, and then flows out from the lower water outlet pipe, and the associated gas enters the heat dissipation outer pipe from the lower gas inlet pipe, and the dried associated gas flows out from the upper gas outlet pipe. In this process, the associated gas can be cooled by the heat dissipation fins, and on the other hand, the associated gas can be heat-exchanged with the clean water circulating in the inner pipe, so as to further reduce the temperature of the associated gas, thereby effectively reducing the temperature of the associated gas. After the associated gas is cooled, the light hydrocarbon and water vapor in the associated gas condense into small droplets. Under the action of gravity, the small droplets flow to the bottom end along the inclined heat dissipation outer pipe, and are discharged through the liquid discharge pipe, so as to separate the light hydrocarbon and water, ensure the good combustion effect of the associated gas and improve the efficiency of the heating furnace. However, the existing drying and cooling device has the following problems:

[0004] The heat dissipation fins are directly connected and fixed with the heat dissipation outer pipe. When the associated gas is cooled, the heat dissipation fins can only use the naked state to complete the temperature cooling with the external environment air, and the cooling time is long and the effect is poor. At the same time, the existing drying and cooling device is usually used by laying a plurality of pipes adjacent to each other, and the pipes are connected and arranged through the adapter, and the overall laying stability needs to be improved.
