A natural gas purification device

Abstract

A natural gas purification device belongs to the technical field of natural gas purification devices. It is characterized in that: the dehydration device includes a plurality of Laval tubes (9) and a separation cylinder (10) below the Laval tubes (9), the separation cylinder (10) is conical in diameter gradually increasing from bottom to top, separating The lower part of the cylinder (10) is provided with a water outlet, the upper end of the separation cylinder (10) is connected with the Laval tube (9), the separation cylinder (10) is provided with an exhaust pipe (7), and the lower end of the exhaust pipe (7) extends Into the separation cylinder (10), the upper end is used to communicate with the conveying pipeline, and the dehydration air inlet cylinder (8) is arranged above the Laval pipe (9), and the Laval pipe (9) passes through the dehydration air inlet cylinder (8) and the outlet of the dust removal device The air port is connected, and the Laval tube (9) is spiral and arranged around the exhaust pipe (7). The natural gas purification device ensures the flow capacity of the pipeline and avoids physical damage to the pipeline; the dehydration system does not require power components, which saves energy.

Description

technical field [0001] A natural gas purification device belongs to the technical field of natural gas purification devices. Background technique [0002] With the development of my country's industry, the improvement of people's living standards and the needs of environmental protection, natural gas, as a clean energy and high-quality chemical raw material, is playing an increasingly important role in the development of the national economy and the improvement of air quality, environmental protection and energy structure. increasingly important role. [0003] The natural gas produced from the formation generally contains a certain amount of impurities such as water, hydrogen sulfide and carbon dioxide. The acidic impurity gas will accelerate the corrosion of pipelines, and the existence of water will bring difficulties to the transportation and processing of natural gas. The lower the temperature at which natural gas needs to be cooled during transportation and processing, ...

Problems solved by technology

These traditional separation methods either need to consume a lot of chemicals, or the process is complicated, the equipment investment and operation costs are high, and the separation efficiency is low.
