输油站热媒—水换热器经多年运行后,由于循环水中含有铁、钙、镁离子和氯离子以及溶解氧含量高,致使热交换设备和管网的腐蚀、结垢严重,导致局部腐蚀穿孔。采用IMC-50-S缓蚀剂,在腐蚀严重的沈阳和熊岳输油站进行了现场试验,试验结果表明,加剂后可使其腐蚀速度控制在0.1mm/a以下,延长了换热器和循环管网的使用寿命,保证了输油安全生产。 After many years of operation, the circulating heat medium water heater has many problems, such as the corrosion of the heat exchange equipment and pipe network and the serious scale formation due to the high content of dissolved oxygen, iron, calcium, magnesium ions and chlorine ions in the circulating water, Corrosion perforation. Field tests were carried out in Shenyang and Xiong Yue oil stations with severe corrosion using IMC-50-S corrosion inhibitor. The experimental results show that the corrosion rate can be controlled below 0.1mm / a after the addition, prolonging the heat transfer Recycling pipe network and the life of the oil to ensure safe production.
