【摘要】：以南帕斯凝析油混炼减二线油品为研究对象,通过添加一定比例环烷酸,考察酸值对20#碳钢在高温油品中的腐蚀影响;采用电化学噪声(EN)分析不同温度下碳钢在高温环烷酸中腐蚀状况。结果表明,20#碳钢受高温环烷酸的腐蚀速率随温度的升高呈现出先增大后减小的规律;随酸值的增大,碳钢的腐蚀速率一直增大。在环烷酸的酸值为10 mg KOH/g,流速为1 m/s时,碳钢在280℃时腐蚀速率最高。
[Abstract]:The effect of acid value on the corrosion of 20 # carbon steel in high temperature oil products was investigated by adding a certain proportion of naphthenic acid. The corrosion of carbon steel in high temperature naphthenic acid at different temperatures was analyzed by electrochemical noise en. The results show that the corrosion rate of 20 # carbon steel increases first and then decreases with the increase of temperature, and the corrosion rate of carbon steel increases with the increase of acid value. When the acid value of naphthenic acid is 10 mg / g and the flow rate is 1 m / s, the corrosion rate of carbon steel is the highest at 280 鈩，
