Problems solved by technology

[0004] The traditional impurity removal and separation device is not ideal for the removal of impurities in oilfield associated gas, and often has shortcomings such as high impurities in the product gas, low purity, and acidity of the gas. Therefore, a four-stage integrated model of oilfield associated gas removal is currently being developed methods and devices are particularly important

Embodiment Construction

[0011] When processing raw gas associated with oilfield gas, the raw gas of associated gas enters the device from the raw gas inlet pipe (1), and enters the deacidification chamber (7) through the stop valve No. 1 (2) and the flow meter No. 1 (3). No. (2) can close the raw gas inlet pipe (1); the associated gas raw gas is deacidified by the slaked lime block (5) in the reaction box (4) in the deacidification chamber (7), and the generated water passes through the leakage The leakage hole (9) on the plate (8) enters the drain pipe (10) of the deacidification chamber, and finally enters the main drain pipe (45). left side. When the deacidification chamber (7) and its internal components fail, the inspection valve No. 1 (6) can be opened for maintenance; the gas after deacidification enters the gravity settlement through the connecting pipe No. 1 (12) and the flow meter No. 2 (11) chamber (13), flow meter No. 2 (11) can record the fluid flow entering the gravity settling chamber...

Abstract

The invention relates to a four-stage integrated method and device for impurity removal of oilfield associated gas. According to the device, related facilities are utilized to remove acidic materialsin a raw material gas, then the acid removed gas is subjected to separation and purification of other solids, liquids and gases in a gravity settling chamber and a cyclonic sedimentation chamber, theseparation of light hydrocarbons and heavy hydrocarbons is carried out in a fine separation chamber, and material classification and impurity removal are carried out for further treatment. The devicehave the advantages of good treatment effect, high separation degree, convenient maintenance and simple operation.

Description

technical field [0001] The invention relates to a device, in particular to a method and device for removing impurities from oil field associated gas in a four-stage integrated mode. Background technique [0002] At present, with the increase of crude oil extraction, the output of oilfield associated gas is also increasing. However, in most oilfields in my country, the oilfield associated gas is directly burned and discharged into the air, which is the "torch" on the oil well. Oilfield associated gas contains a large amount of solid and liquid impurities, toxic gases and recyclable resources. If oilfield associated gas is not treated effectively, it will affect its recovery and reuse, which will also cause serious environmental pollution and huge waste of resources. Therefore, it is necessary to efficiently remove impurities from associated gas in oilfields. [0003] Traditionally, the impurity removal device for associated gas in oilfields has not performed raw gas deacidifi...
