Description

Technical Field

[0001] The utility model relates to the technical field of natural gas pretreatment, in particular to a natural gas pretreatment purification tower. Background Art

[0002] Natural gas refers to all gases that exist naturally in nature, including gases formed by various natural processes in the atmosphere, hydrosphere, and lithosphere (such as oilfield gas, gas field gas, mud volcano gas, coalbed methane, and biogenic gas, etc.). From an energy perspective, the narrow definition refers to a mixture of hydrocarbons and non-hydrocarbon gases naturally stored in the strata. It is one of the main natural resources in social development. Generally, natural gas needs to be pre-treated in a pre-treatment purification tower after extraction to prevent some impurities from entering the subsequent process. Separating water vapor from natural gas can effectively prevent impurities from freezing at low temperatures and clogging equipment and pipelines.

[0003] At present, some natural gas pre-treatment purification towers pass the natural gas into a condensation chamber for cooling when performing water vapor separation treatment, so that the water vapor is first liquefied to achieve the purpose of separation. However, the natural gas mostly passes directly through the condensation chamber, which results in poor cooling effect of the condensation chamber on the natural gas and reduces the treatment efficiency of the water vapor.
