Description

Technical Field

[0001] The invention relates to the technical field of natural gas filtering and dehydration, and in particular to a natural gas filtering and dehydration device. Background Art

[0002] Generally speaking, during the process of drilling natural gas, the natural gas flowing out of the well is usually saturated with gas phase water, and even carries a certain amount of liquid water. In the process of using natural gas, the water in the natural gas often causes serious consequences, such as water blocking valves, pipes and equipment in the natural gas pipeline. For this reason, natural gas manufacturers need to dehydrate the natural gas.

[0003] The dehydration of natural gas is usually achieved by a natural gas dehydration device. The dehydration methods used in the natural gas dehydration device include cryogenic method, solvent absorption method, solid adsorption method, chemical reaction method and membrane separation method. The existing dehydration of natural gas is usually carried out by cooling, that is, the natural gas is introduced from the bottom of the dehydration tower, and then cold air is introduced from the top of the dehydration tower, and then the cold air and the natural gas are in convection contact to condense the water therein and remove it. However, the existing dehydration device usually requires multiple dehydration processes to completely remove the water therein, which is inefficient, requires a lot of equipment, and is costly.
