Problems solved by technology

At present, cooling natural gas is usually used for dehydration, that is, the natural gas is introduced from the bottom of the dehydration tower, and then the cold air is introduced from the top of the dehydration tower, and then the cold air is convectively contacted with the natural gas so that the water in it is condensed and removed, but the existing The dehydration device usually requires multiple dehydration processes to completely remove the water in it, which is inefficient, requires a lot of equipment, and is costly

Abstract

The invention belongs to the technical field of natural gas filtration and dehydration, and discloses natural gas filtration and dehydration equipment. The top of a folded plate is welded with an upper supporting plate, and a cavity is formed between the folded plate and a tank body. A cyclone separator is arranged at the upper part of the upper supporting plate; one end of an air inlet pipeline is communicated with the cavity in the tank body; one end of an exhaust pipeline is communicated with the bottom of the tank body; and a cover body assembly covers the top of the tank body. The cycloneseparator and the demister are arranged, natural gas entrained with liquid and solid particles enters the cavity formed by the tank body and the folded plate through the gas inlet pipeline and then the entrained liquid and solid particles are filtered through the cyclone separator and the demister, the gas is exhausted from the exhaust pipeline after filtering, the gas component analyzer arrangedin the exhaust pipeline can detect the filtered gas, the detection information is displayed on the upper part of the display screen and the operator can check the detection information conveniently.

Description

technical field [0001] The invention relates to the technical field of natural gas filtration and dehydration, in particular to natural gas filtration and dehydration equipment. Background technique [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. During the use of natural gas, the presence of moisture in natural gas often causes serious consequences, such as moisture blocking valves, pipes and equipment of natural gas pipelines. For this reason, natural gas manufacturers need to dehydrate natural gas. [0003] The dehydration work of natural gas is usually realized by natural gas dehydration unit. The dehydration methods used in natural gas dehydration units include low temperature method, solvent absorption method, solid adsorption method, chemical reaction method and membrane separation method. At present, cooling...
