从气井中开采出来的天然气通常带有一部分液体和固体杂质，如凝析油、凝析水、地层水和岩屑粉尘等，必须在井场和集气站进行气液（固）分离处理，把它们从天然气中分离出去。过去天然气中水液（固）的分离国内外通常采用的分离设备有重力式分离器，旋风分离器，扩散式分离器等 Natural gas extracted from gas wells usually contains some liquid and solid impurities such as condensate, condensate water, formation water and cuttings dust, which must be separated by gas-liquid separation at the well site and gas gathering station, Separate them from natural gas. In the past the separation of natural gas in the liquid (solid) separation equipment commonly used at home and abroad are gravity separator, cyclone, diffusion separator
