High-efficiency natural gas dehydration treatment device and method

Abstract

The invention discloses a high-efficiency natural gas dehydration treatment device and method. The device comprises a removal tower and a dehydration tank, one side of the bottom of the removal tower is connected with a gas inlet pipe, and the gas outlet end of the removal tower is connected with a gas inlet of the dehydration tank through a gas transmission piece; a plurality of through holes are formed in the inner wall of the dehydration tank, and an interlayer is arranged between the outer wall and the inner wall of the dehydration tank and used for containing adsorbents; and a driving cylinder is arranged in an inner cavity of the dewatering tank, the outer wall of the driving cylinder is connected with a flow guide spiral piece, a driving piece is arranged at the top of the dewatering tank and used for driving the driving cylinder to rotate, a water drainage pipe is connected to the bottom of the dewatering tank, a fixing cylinder is arranged in an inner cavity of the driving cylinder, and an air inducing piece is connected to the bottom of the fixing cylinder. The natural gas dehydration device is designed according to existing requirements, moisture in natural gas can be efficiently removed through cooperative use of the removal tower and the dehydration tank, the to-be-dehydrated natural gas can be pretreated through the removal tower, and follow-up natural gas dehydration treatment is facilitated.

Description

technical field [0001] The invention relates to the technical field of natural gas, in particular to a high-efficiency natural gas dehydration treatment device and method. Background technique [0002] Natural gas is stored in underground porous rock formations, including oil field gas, gas field gas, coal bed methane, mud volcano gas and biologically generated gas, etc., and a small amount comes from coal seams. Therefore, the associated gas in the oil field or the natural gas produced in the gas well contains too much water, and it needs to be dehydrated to remove the water in the natural gas, so as to avoid serious consequences caused by the presence of water in the natural gas, or the formation of natural gas hydrates to block valves, Piping and equipment. [0003] In the natural gas dehydration device disclosed by the existing patent notification number CN 110923027 B, the natural gas is processed through the primary filter intake assembly and the filter exhaust assemb...

AI Technical Summary

Problems solved by technology

[0004] However, the above-mentioned devices mainly use continuous adsorption for dehydration, and the adsorbent often needs to be regenerated. When the adsorption process continues, the dehydration efficiency is low, which is not conducive to the continuous dehydration of natural gas, and needs to be improved.
