- 中文摘要: 本文是以鈉-24為示蹤劑。實際應用於紙漿工廠的多效蒸發罐中,以探求黑液在蒸發罐中的留滯時間及流動型態。放射性鈉-24(約10毫居里)與擔體Na2CO3混合後,一起注入蒸發系統之密閉容器中,藉放射線連續記錄法,求出各位置的放射性強度對時間之變化,由此推斷蒸罐內黑液的滯留時間及流動型態。
- 英文摘要: In this study, the radioactive Na-24 wasused as a tracer to measure the residence timeand flow pattern of black liquor in multipleeffect evaporation system of pulp productionprocess. About 10 mci of Na-24 mixed withcarrier was added into the evaporators, and theflow behavior of the added tracer was monitoredcontinuously from the attached detector atvarious points on the outside wall of the evap-orators. From the radioactivity vs. time curve,the mean residence time and flow pattern wereestimated.
