Rectification-type supersonic cyclone separator

Abstract

The invention discloses a rectification-type supersonic cyclone separator belonging to the field of moisture-containing natural gas dehydration. The rectification-type supersonic cyclone separator comprises a cyclone, a separator and a diffuser which are sequentially connected, wherein a rectifier is arranged in the diffuser; and when the rectification-type supersonic cyclone separator is used, moisture-containing natural gases enter the separator and are subjected to gas-liquid separation after being swirled by the cyclone so as to form swirled dry natural gases, and the swirled dry natural gases flow out of the rectification-type supersonic cyclone separator after being rectified by the rectifier. The rectification-type supersonic cyclone separator disclosed by the invention is small in size and high in efficiency, and the moisture-containing natural gases can be subjected to gas-liquid separation without other chemical agents; in addition, water vapor in the natural gases can be condensed and separated in a low-temperature and low-pressure environment by only using the own structure of the separator, and then, the left dry natural gases are stored in a diffusion runner provided with the rectifier to ensure that the pressure and the temperature are restored, so that swirling effects in the dry natural gases are eliminated.

Description

technical field [0001] The invention relates to the field of wet natural gas dehydration, in particular to a rectification type supersonic cyclone separator. Background technique [0002] The natural gas extracted from the wellhead is a mixed gas containing impurities such as water vapor, sulfide and carbon dioxide. During the natural gas pipeline transportation process, the water vapor in the mixed gas will condense when it is cold, so that the natural gas contains liquid water. The existence of liquid water will not only reduce the effective transportation capacity of natural gas pipelines, but also form hydrates in serious cases, which will block natural gas pipelines and cause major accidents. Therefore, wet natural gas must be dehydrated. [0003] At present, conventional natural gas dehydration methods include triethylene glycol method, molecular sieve method and membrane separation method. But above-mentioned three kinds of treatment methods all need huge system trea...

Problems solved by technology

[0005] But above all supersonic condensation separators and above-mentioned methods all no matter the mode that it adopts is the first swirling flow and then condensation or the first condensation and then swirling flow, these technologies all do not consider the pipeline transportation problem of the natural gas that comes out from the diffuser, namely The natural gas from the diffuser is a natural gas with a tangential swirl, and the natural gas with a tangential swirl will have a great friction effect with the inner wall of the pipeline during the pipeline transportation, so that the transportation is extremely difficult. Instability, resulting in immeasurable losses
