暂态技术研究高含H2S和CO2近中性溶液中套管钢的界面反应
Electrochemical Transient Technique of Processes Occurring in Tubular Steel-Neutral Solution Interface in H2S and CO2 Containing Environment
摘 要
采用电位阶跃技术研究在H2S和CO2共存的近中性溶液中套管钢/溶液界面和反应过程。应用数学模型分析界面反应中氢吸附过程、负离子脱附过程和氢吸收过程的变化规律。当阶跃电位为50 mV, 界面反应由氢吸附过程控制, 当阶跃电位超过50 mV, 界面反应由负离子脱附过程控制。研究显示, 在含50% H2S(pH=5.9)环境中, 加入CO2提高了界面负离子脱附、氢吸附和氢吸收反应速率。

Abstract
Electrochemical transient technique was used to study the processes in tubular steel-solution interface in the neutral solution containing H2S and CO2. The processes consisted of anion desorption, hydrogen adsorption and hydrogen absorption were analysized using steel-solution interface models. The process in the metal-solution interface was controlled by hydrogen adsorption at the potential step of -50 mV, however, by anion desorption at the potential step higher than -50 mV in the solution containing H2S and CO2. The results show that adding CO2 increased anion desorption rate, and enhanced hydrogen adsorbing and absorbing in high H2S containing solution.
