摘要

以氦氣為追蹤物測試商業工場反應器的流態，並利用滯留時間分佈曲線方法計算　接觸效率，太低的接觸效率意謂著嚴重的反應器流態不均勻現象。利用量測結果分別計算兩種裝填方式下的反應器接觸效率，疏式裝填方式時接觸效率為48%，此工場可能有channeling的現象。觸媒裝填改為密式裝填後，接觸效率提升為86%，表示密式裝填的流態比疏式裝填均勻，且密式裝填後脫硫率有大幅提升。利用此方法可在不影響工場操作的情況下，判斷反應性不佳，是否由流體分佈不均勻造成。

There are two main reasons for the lower sulfur conversion than expected in the desulfurization plant. One is the channeling phenomenon in the reactor bed, the other one is the deactivation of catalyst. The Refining & Manufacturing Research Center developed an on-line He inspection method to find the flow pattern for the fixed reactor bed. The present paper presented a case study example for the flow pattern measurement of reactor bed. It included measured method, data analysis. The contact efficiency was used to represent the flow pattern. The higher contact efficiency mean the flow pattern is more like plug flow in the reactor. The lower contact efficiency means bad flow pattern in the reactor. The contact efficiency for the sock loading plant has lower the value than the plant with dense loading. The plant with dense loading also has higher sulfur removal conversion.
