摘要

廢潤滑油為含有重金屬的有機廢棄物，對環境的汗染相當嚴重，本研究採用疏水性薄膜進行廢潤滑油回收分離，其滲出量隨著操作溫度的提高而增加，但超過82℃以上，則增加不多，滲出量亦隨著操作壓力提高而增加，但高於90psi後，其增加量有限，本實驗所使用的薄膜對廢潤滑油中的氮化合物脫除率超過60%，鋅化合物的脫除率超過60%，大部份的鈣及鋁的化合物均可被去除，至於硫化合物的脫除率不高及對芳香烴的影響很小，利用水洗滌以分離廢潤滑油中的金屬雜質並不適合，回收的廢潤滑油色度6.5，色度稍為高一些。

Hydrophobic polymeric membranes were used to purify used lube oil in this study. Flow rate of permeate was directly proportional to both the operating pressure (~90psi) and temperature (~83℃). The flow rate increased slightly with increase of pressure and temperature when P＞90 psi and T＞83℃. Nitrogen and zinc contents in permeates can be reduced to below 40% of the feed oil. Most Calcium and Aluminum contents can be removed from the used lube oil. The polymeric membrane was not effective for removal of sulfur compound and Aromatics. A water-washing method was not suitable to remove metal contaminants for purifying used lube oil. The polymeric membrane process can provide a purified oil product having 6 of color index, which is higher than that of fresh lube oil.
