摘要:

随着天然气消费市场的日益增长,对高含硫化氢气田的勘探开发逐渐提上日程。对于从矿场开采出来的含有CO2、H2S的天然气,水分的存在会导致具有强腐蚀性的酸液形成,造成管线、设备、仪表的腐蚀,在一定条件下还会形成水合物堵塞管路、设备,影响平稳供气。为了设计油气加工装置和管道系统,需要知道天然气中的水含量。本文主要介绍了现有的高含硫天然气饱和水含量的计算方法,并对每种方法的估算依据、及估算步骤以及适用性进行了分析,推荐出了适合于高含硫天然气含水量的计算方法。

Abstract:

In order to design gas processing plant and pipeline systems,it is necessary to determine the water content in natural gas. In this paper,the saturated water content in high-sour natural gas is calculated by some methods,then analyses the basis,steps and applicability of each method,finally recommends a suitable method for the calculation of water content in high- sour natural gas.
