1 故障现象及原因分析1999年 4月 ,正当用氧高峰时 ,一套FON 50 /10 0型分馏塔突然出现故障 ,液氧液位在 4 0 0~4 50mm ,产量、纯度下降 ,上塔压力偏高。第二天 ,塔无法正常工作 ,氮排空阀、馏分放空阀全部打开 ,氧纯度下降到 93%左右。对液空、液氧、氮气纯度进行化验 ,液空含氧 36%、液氧纯度为98%O2 、氮气纯度为 99 9%N2 。根据出现的现象和化验数据 ,我们认为是冷凝蒸发器内部泄漏。又根据冷凝蒸发器的内部构造和故障变化过程 ,判定是进下塔的加热管与冷凝蒸发器结合部位焊口开裂的可能性较大。2 修复措施将分馏塔进行加热后… 相似文献

The thermal stability of amorphous ternary hydrides Mg_(50)Ni_(50)H_(54) and Mg_(30)Ni_(70)H_(45) and their corre-sponding amorphous binary alloys Mg_(50)Ni_(50) and Mg_(30)Ni_(70) were studied with X-ray diffraction(XRD) and differential scanning calorimetry(DSC). Samples of the amorphous alloys were preparedby mechanical alloying and the amorphous hydrides were obtained by charging the alloys with gas-eous hydrogen at 3.0 MPa and 423 K. It was found that the amorphous hydrides released most oftheir hydrogen before the crystallization of the essentially hydrogen depleted amorphous alloy. Thecrystallization temperature of amorphous Mg_(50)Ni_(50)H_(54) elevated and that of amorphousMg_(30)Ni_(70)H_(45) did not change in relation to the original binary amorphous alloy. This is very excep-tional for amorphous hydrides. The reason for the effects of hydrogen absorption/desorption on thecrystallization of amorphous alloys was discussed. 相似文献
