| 5. | To verify the effectiveness of the proposed hybrid fnn , this thesis addressed the estimation problem for the frozen point of light cyclic oil in a fluidized catalytic cracking unit ( fccu ) in a refinery . based on the sample data collected from the industrial unit , we built a soft sensor model by using an above hybrid fnn 最后,针对某炼油厂催化裂化装置主分馏塔轻柴油凝固点的软测量估计问题,本文基于工业现场所采集的样本数据,建立了混合结构神经网络模型,并讨论该模型的在线自学习问题,同时与多层前向bp网络、径向基函数rbf网络模型进行了比较。 |
| 6. | The risk assessment and the risk sequence of the equipment and piping of catalytic cracking unit in lanzhou petrochemical company were defined by applicating the risk - based inspection ( rbi ) technology , and the inspection program which offers scientific basis for repairing schedule and strategy was made according to different equipment , piping and different risk classes 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。 |
