| 中文摘要 | 煉油廠的加氫處理工場為提升煉量,在既有的固定床反應器前面加裝一座上流式反應器,上流式反應器具有低反應器壓差的特點,雖然觸媒量佔23%,但該反應器壓降才佔總反應器壓降的7-10%,可以大幅減少循環壓縮機的負荷,同時煉量可提昇25%,相當適合使用在去瓶頸的案例。然而此種設計仍有諸多操作上的問題,在操作操作初期因進料黏度偏高,使得高壓高溫分離槽液位及上流式反應器溫度的晃動,上流式反應器徑向溫差及第一座固定床反應器壓差,也很容易偏高。雖然工場在這部份操作得相當好,但其他煉廠深受此問題的困擾,未來還需持續關注此問題。在上流式反應器與固定床反應器之間沒有加熱爐,使得固定床的溫度調控彈性受到限制,無法同時充分運用各反應器的觸媒活性,未來須針對這些操作問題逐一改善,讓此上流式反應器發揮最大的功效。 |
| 英文摘要 | Adding a up-flow reactor (UFR) in existed fixed-bed reactors (FBR) systems is a solution to increase the operation capacity of hydrotreating process in refinery. The future of UFR is low pressure drop. The pressure drop of UFR is only 7-10% of total reactor pressure drop even though its catalysts are 23 wt% and operation capacity increase 25%, so the duty of recycle compressor is very low. The combination is very suitable for debottleneck situation. However this design still has several drawbacks. During start of run, the liquid level of high-pressure high-temperature separator and UFR temperature has the problem of shake. The radial temperature difference of UFR and the pressure drop of the first FBR can be high easily during operation. Other refineries suffer from such kinds of problem although we had good operation results. Such problems need to be concerned in the future. There is not a heating furnace between UFR and FBR, so the temperature adjustment of FBR is limited, and catalysts activities of FBR can't be used completely. Those problems must be improved in the future to promote the function of the UFR. |
