浅析加氢精制喷气燃料银片腐蚀的影响因素

An Analysis of the Influencing Factors in Sliver Strip Corrosion in Hydrogenated Jet Fuel

硫化氢和元素硫是直接造成加氢精制生产过程中银片腐蚀不合格的物质。从生产环节入手，对汽提效果、非计划停工、原料性质、水、生产设备对3号喷气燃料银片腐蚀的影响进行了分析，并对生产中存在的问题提出了用精制油代替粗汽油作冷回流介质，用氢气代替水蒸气作汽提介质等整改措施。

Hydrogen sulfide and dement sulfur are the main materials which directly cuase the unqualification of silver strip corrosion during jet fuel hydrotreating. The influencing factors , such as stripping tower effect, non - plan shutting down, raw materials properties, water and production equipments, are analyzed. In this paper, methods guaranteeing qualification of silver strip corrosion,including using jet fuel instead gasoline as cooling medium, using hydrogen instead vapour as stripping medium, are put forward.
