摘要
近年来,随着炼厂加工高硫高酸劣质油比例的增加,设备腐蚀问题日益突出,给防腐工作提出了新的挑战,文章以焦化装置主要设备与管线的腐蚀情况出发,从多年的防腐工作实践中,总结出了一些宝贵的经验。
With the degradation of crude oil,especially the increase of its acid and sulphur, the existing equipment and piping of delayed coking unit have suffered from the severe corrosion of the low-quality residuum. In the paper,the corrosion of residuum in delayed coking unit have been described and the anti-corrosion measures have been presented.
