【摘要】 <正>在炼油厂的常减压炼制装置系统中,管式热交换器使用非常普遍。在某炼油厂中,其使用的管式热交换器发生了管道“爆裂”事故,致使生产停顿,造成了严重的经济损失。经检查发现,在热交换器管道内部有黑色沉积物。通过检验与分析,对管道内部沉积黑色物质和钢管材质进行了气相色谱-质谱联用分析、能谱分析,找到了管道发生爆裂的原因。更多还原

【Abstract】 By the methods of GC/MS and ESEM (environmental scanning electron microscope), the black material inside the steel tube of the heat exchanger in the oil refining system was researched to ascertain the composition and the origin. The results indicate that the mixed gas in the steel tube changed into the condensate and sediment. The sediment reacts with the steel wall, and change the character of the medium in heat exchanger, which results in the steel tube to burst violently at a result of internal normal pressure.更多还原
