Abstract

A vortex tube device for condensing and separating natural gas moisture and light hydrocarbons belongs to the technical field of gas refrigeration and gas-liquid separation. The vortex tube device is added with a liquid discharge structure and a separation and recovery unit. In this way, the swirling and condensed droplets in the vortex tube can flow out of the vortex tube in time through the liquid discharge structure, preventing it from re-evaporating in the tube and returning to the air flow, thus greatly improving the separation efficiency of water and light hydrocarbons. In addition, the pressure difference at different parts of the device is cleverly used to make the gas flowing out of the tube together with the condensate return to the cold air flow of the vortex tube after the gas-liquid separation to realize recovery. The invention has the advantages of simple structure, convenient use and maintenance.

Description

technical field [0001] The invention relates to a vortex tube device for condensing and separating natural gas moisture and light hydrocarbons, belonging to the technical field of gas refrigeration and gas-liquid separation. Background technique [0002] As a kind of clean energy, natural gas has been paid more and more attention by people. Natural gas extracted from gas wells contains certain water vapor and condensable hydrocarbons after preliminary treatment. These condensable vapors and hydrocarbons are very easy to form liquid water, solid ice or hydrate during the transportation of natural gas, which seriously affects the transportation of natural gas and the service life of pipelines. Therefore, the removal of these condensable vapors and hydrocarbons in natural gas is an indispensable link. At present, the devices for separating these condensable vapors and hydrocarbons are cyclone separators and supersonic separators. The cyclone separator only relies on the cycl...
