水中气态烃一般系指溶解干水中的甲烷、乙烷、丙烷及丁烷等气体。如何从水中提取这些烃类气体,迄今还没有十分理想和统一的方法。本文在前人研究的基础上,从水的结构效应方面,结合一些具体试验,对水中烃类气体的提取进行研究。 一、脱气原理 溶解于水中的烃类气体,是不带电荷的,既不能极化附近的水分子,也不与水中电解质产生电解反应。它以分子的形式存在于水分子之间结合的“孔隙”之中,换句话说,这些烃类气体的溶解和赋存决定于水的结构。
Gaseous hydrocarbons in water generally mean gases such as methane, ethane, propane and butane dissolved in dry water. How to extract these hydrocarbon gases from water has not been a very ideal and uniform method so far. Based on the previous studies, this paper studies the extraction of hydrocarbon gas from water in terms of the structural effects of water combined with some specific tests. First, the principle of degassing Hydrocarbon gas dissolved in water is uncharged, neither the polarization of water molecules in the vicinity, nor electrolysis of electrolytes in water. It exists in molecular form in the “pores” between water molecules. In other words, the dissolution and occurrence of these hydrocarbon gases depend on the structure of water.
