Abstract

The invention discloses a performance evaluation system and method for a filter element for moisture filtration, and belongs to the field of chemical analysis. The system comprises a feed gas mixer, agas-liquid separator and a liquid-mist separator. A natural gas inlet is formed in the side wall of the feed gas mixer, and an atomized liquid inlet and a mixed moisture outlet are formed in the topwall of the feed gas mixer. A mixed moisture inlet is formed in the side wall of the gas-liquid separator, and a gas mist outlet is formed in the top wall of the gas-liquid separator. A gas mist inletis formed in the side wall of the liquid-mist separator, a filtered gas outlet is formed in the top wall of the liquid-mist separator, a filter element is detachably arranged in the liquid-mist separator, and an upper port of the filter element is communicated with the filtered gas outlet. The mixed moisture outlet is communicated with the mixed moisture inlet through a mixed moisture pipeline, the gas mist outlet is communicated with the gas mist inlet through a gas mist pipeline, and the filtered gas outlet is communicated with a filtered gas pipeline. A first sampling opening is formed inthe gas mist pipeline, and a second sampling opening is formed in the filtered gas pipeline. The method can be used for accurately evaluating the performance of the filter element.

Description

technical field

[0001] The invention relates to the field of chemical analysis, in particular to a performance evaluation system and method of a filter core for moisture filtration. Background technique

[0002] At present, the high-pressure raw natural gas produced from the wellhead is mostly transported to the treatment plant by wet gas for purification. Since the raw natural gas contains various impurities, such as liquid hydrocarbons, free water, chemical additives, etc., these will affect the treatment. In order to ensure the normal operation of the processing equipment in the plant, it is necessary to pre-treat the raw natural gas to remove the above-mentioned impurities as much as possible.

[0003] In the related technology, the raw natural gas is firstly separated into gas and liquid by a gas-liquid separator, and most of the liquid phase hydrocarbons, free water and solid chemical additives are removed by gravity, and then introduced into the liquid mist separator ...
