摘要： 分析总结储罐内部介质三相区域（含油污水区域、油相区域、气相区域）腐蚀原因，确定易腐蚀减薄区域。建立腐蚀泄漏后液体影响范围数学模型。以某油库汽油罐含油污水区域泄漏为例，计算储罐泄漏液体影响范围，为确定储油罐泄漏安全防护距离及应急救援提供依据。相对于油相区域、气相区域，含油污水区域对储罐内壁腐蚀比较严重；相对于油相区域—气相区域交界面，含油污水—油相区域交界面腐蚀较为严重。

关键词: 储油罐, 腐蚀原因, 泄漏, 影响范围, 安全距离

Abstract: The causes of corrosion in the three- phase area for the storage tank (oily sewage area, oil phase area, gas phase area) were analyzed and summarized,then the areas that are liable to corrosion and leakage were determined. The affected range model of released liquid after corrosion of tank was established. Taking the leakage of oily sewage area in a gasoline tank of an oil depot as an example, the involved area of released liquid was calculated and analyzed to provide basis for determining safety protection distance and emergency rescue of oil tank leakage. Compared with oil- phase area and gas- phase area, the oil- bearing sewage area has serious corrosion on the inner wall of the tank. Compared with the oil- gas interface, the oil-bearing sewage oil interface is corroded seriously.

Key words: oil tank, causes of corrosion, leakage, affected range, safety protection distance
