Problems solved by technology

[0002] Gas purification devices have always been a problem for mud loggers. For many years, the mud logging industry can only use the method of dehydration and drying to remove water and dry natural gas. This method uses chemical methods for drying. Anhydrous calcium chloride is placed in a container as natural gas Water is adsorbed by calcium chloride when flowing through calcium chloride, but sometimes some powder of calcium chloride is mixed in the gas and enters the chromatograph to block the capillary and chromatographic column of the chromatograph, causing damage to expensive precision instruments

Embodiment Construction

[0031] The present invention will be further described in detail below with reference to the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0032] like figure 1 As shown, a gas purification device for a deaerator provided by the present invention includes: a water removal tank 100 , a decontamination tank 200 and a cleaning tank 300 .

[0033] The water removal tank 100 includes an air intake line 110 that penetrates into the bottom of the tank, and is mainly used to remove a large amount of water in the gas. During the flow of the mixed gas from bottom to top, condensation will occur due to different substances in the gas, different quality and liquefaction point. , the condensation effect of the water is the best here, and some impurities of the components will also be incorporated into the water. As a preferred material for the intake pipe, the non-hydrophilic and lipophilic Teflon material, the condensed water ...

Abstract

The invention discloses a gas purification device and a purification method for a degasser. The gas purification device comprises a water removal tank, a dirt removal tank and a cleaning tank; the water removal tank comprises a gas inlet pipeline which goes deep into the bottom of a tank body and is used for removing moisture in gas; the dirt removal tank communicates with a gas outlet of the water removal tank, comprises a cleaner arranged inside, and is used for removing impurities in the gas; the cleaning tank communicates with a gas outlet of the dirt removal tank, comprises a cleaning sheet inside the cleaning tank, and is used for further removing the moisture in the dirt removal tank. According to the gas purification device, the impurities in the gas are removed through the dirt removal tank, multi-stage purification parts are connected with one another in a penetrating manner, and thus the purification effect is guaranteed. The invention also provides the gas purification method for the degasser. According to the gas purification method, an evaluation factor is calculated and is input into a fuzzy controller, so that the opening degree of a throttle valve is accurately controlled, and the gas purification effect is guaranteed.

Description

technical field [0001] The invention relates to the field of oil and natural gas purification, in particular to a gas purification device for a degasser and a gas purification method for the degasser. Background technique [0002] Gas purification devices have always been a problem for logging personnel. For many years, the logging industry can only use the method of dehydration and drying to remove water and dry natural gas. This method is mostly chemical drying. Anhydrous calcium chloride is placed in a container as natural gas. When flowing through calcium chloride, water is adsorbed by calcium chloride, but sometimes some powders of calcium chloride are mixed in the gas and enter the chromatograph to block the capillary and chromatographic column of the chromatograph, causing damage to expensive precision instruments. Furthermore, the natural gas separated from the degasser is also impure oily impurities entering the chromatograph. For this reason, we have specially dev...
