普光高含硫气田水中H2S去除技术研究

文章探讨了通常用于水中H2S去除的方法,对比方法的优缺点,提出以NaClO为主要脱硫剂的处理方法。通过对采出水的脱硫氧化剂优选试验、NaClO连续脱硫试验,并将试验研究结果应用于普光高含硫气田水脱硫处理。试验证明:采用NaClO可以安全、高效地去除采出水中的H2S,处理后的气田水中硫化物的含量小于1mg/L。

Removal Technology of H2S in Water in Puguang High Sulfur Gasfield

After the discussion of typical H2S removal methods in water and the advantages and disadvantages comparison between different methods,this paper presents a new approach which chooses the NaClO as the main desulfurizer.After the produced water desulfurization oxidizer preferred experiment and NaClO continuous desulfurization experiment,the experiment results are applied into the Puguang high sulfur gasfield water desulfurization treatment.The experiment results show that: the H2S in the water can be safely and efficiently removed by using NaClO,and the sulphide content is less than 1 mg/L in treated gasfield water.
