中文摘要 | 本計畫係探討當RDS工場實際進料比設 計規範輕,導致製程上觸媒雖然延長操作 週期,但仍可能擁有過剩觸媒活性的因應研究。本實驗利用試驗工場進行提溫試驗,計算重 質油轉化率及觸媒衰退速率後,依據試驗工場的測試結果調整現場的反應溫度, 由 365 ℃ 提高 12 ℃的操作溫度,可提高 343 ℃+轉化率 2-3 %。提高反應溫度則反應器出口及分 餾塔入口溫度均會提昇,相對上分餾塔的熱源增加,可提高分餾塔的分離效率,而降低低硫 燃油中的汽柴油含量。 提高反應溫度 12 ℃,可使低硫燃油中的汽柴油含量降低 3.3 %。 同時提高反應溫度操作,會提高觸媒的衰退速率,可充份利用觸媒活性,提高觸媒的使用率 。由現場實地測試,證明試驗工場測試數據的準確性相當高,同時經過經濟效益評估,提高 12 ℃的操作溫度,每個月可增加近二千萬的經濟效益。 |
英文摘要 | For CPC RDS plant, the feed property is better then design specification, so when the plant is shut down the spent catalyst still have some residual activities. For the prupose of using catalyst economically, we study the effect of increasing reaction temperature on residual conversion and catalyst decay rate in pilot plant to obtain RDS plant temperature raising data base. Base on these data, raising the reaction temperature of RDS plant from 365 ℃ to 377 ℃ improve 2-3 wt% 343 ℃ + conversion. By the way, the fractionator efficiency is also improved due to higher reaction outlet temperature, the analytical data show that the gas oil and diesel content of LSFO is 3.3 wt% lower. Monitering the RDS catalyst life and using the residual activity by raising reaction temperature is a economic way of RDS catalyst using. The economic evaluation result show that the benefit can improve twenty million dollar per month. In this test the pilot plant data are approved to have high accuracy on applying to RDS plant operation prediction. |
