考察了加氢裂化装置高压空冷器加工高硫原油后出现的腐蚀问题，并进行了加注sy DY - 101加氢裂化阻垢缓蚀剂的工业试验。
The corrosion happened on the high-pressure air cooler of the hydrocracking unit when processing sour crude was investigated, and corrosion inhibitor SYDY-101 was added for solving the problem.
结果表明，SYDY-101加氢裂化阻垢缓蚀剂能有效地阻止和延缓空冷设备及管线因硫含量过高而引起的腐蚀。
The result showed that the said corrosion inhibitor could effectively inhibit and retard the corrosion of the air cooler and pipes which caused by the high-sulfur content of the oil.
