在油水混合物中亚硫酸酯分解、疲劳腐蚀和电化学腐蚀是H2S影响的一些实例。为保护管线和井设备,必须将这类气体降低到最小值。一种最好的方法是用H2S消除剂。研究压力和反应时间对H2S消除剂腐蚀控制效率的影响有极高的价值。本文用试验方法研究了在不同压力下消除剂与H2S反应效率的变化情况。为得出其对消除剂性能的影响,研究了气体浓度与反应时间的关系。结果表明大部分消除剂消耗H2S发生在最初的5min,在反应发生后降低压力会降低消除剂的效率。消除剂浓度也是一个变量,当采用大比率(600∶1)消除剂后,H2S浓度明显降低,但该比率超出了推荐标准。
Sulfite decomposition, fatigue corrosion, and electrochemical corrosion in oil-water mixtures are some examples of H2S effects. To protect pipelines and well equipment, this type of gas must be minimized. One of the best methods is to use H2S eliminators. It is of great value to study the effect of pressure and reaction time on the efficiency of H2S scavenger corrosion control. In this paper, the experimental method was used to study the effect of eliminating agent and H2S on the reaction efficiency under different pressures. To determine its effect on the performance of the eliminator, the relationship between gas concentration and reaction time was studied. The results show that most of the eliminators consume H2S for the first 5 minutes and reducing the pressure after the reaction reduces the effectiveness of the eliminator. Eliminator concentration is also a variable, and the H2S concentration is significantly reduced when a high ratio (600: 1) eliminator is used, but this ratio is outside the recommended standard.
