The corrosions can be greatly mitigated by injecting neutralization corrosion inhibitor at the inlet of 1st- stage air cooler,selecting carbon steel or CMn steel with a tensile strength of less than 44 MPa or 08Cr2AlMo material.

• 在一级空冷器入口前增设中和缓蚀剂和水的注入点,或选用抗拉强度不大于414 MPa的碳钢或碳锰钢,或选用08Cr2AlMo材料,可大大缓解上述部位的腐蚀问题。
