摘要通过运用基于风险的检验( rbi )技术对兰州石化公司300万吨年重油催化裂化装置的静设备和管道进行风险评估和风险排序，针对不同的设备，不同的风险等级制定了相应的检验策略，为制定装置的检修计划和长期的检修策略提供了一种科学方法。 |
| 7. | It is shown that the gam and alsphene in the seven catalytic stocks were not very high except in residual oil ; the saturate hydrocarbons in all seven were hig her ; aromatic contents were lower except in slurry oil and recycle oil , therefore , t he s even catalytic stocks except slurry oil and recycle oil are all good feedings of catalytic cracking unit
分析测定结果表明，这7种催化原料油除常渣外，胶质沥青质含量均不高；饱和烃含量均较高；芳烃含量除油浆、回炼油外，其余原料含量均较低，所以除油浆、回炼油外，均是作催化裂化的良好原料。 |
