Abstract

This paper presents a comprehensive experimental and techno-economic evaluation of used engine oil ultrafiltration using ceramic and polymeric tubular membranes. Both laboratory and pilot-scale studies were conducted using KUFE ceramic tubular membranes (Ceramic Filter LLC) and F1 polymeric tubular membranes (Vladipor R&D Center). The optimal temperature and pressure were identified as 383 K (110°C) and 0.4 MPa respectively for ceramics membrane, and 343 K (70°C) and 0.4 MPa respectively for polymeric membrane. An industrial plant layout was proposed with membrane unit staging and pump selection to maintain turbulent flow, and minimize fouling. Ceramic membranes exhibited higher specific productivity (0.014 m³ m⁻² h⁻¹) compared to polymeric membranes (0.006 m³ m^–2 h⁻¹). Despite their lower flux, polymeric membrane systems proved 20% more cost-effective at maximum throughput due to significantly lower capital and operating expenditures. The cost for ultrafiltration treatment of used engine oil ranges from 20000 to 25000 RUB/m³ (250–312 USD/m³), which is economically attractive comparing to the cost of fresh Group II base oil (70000 RUB/m³, or 850 USD/m³).

废旧机油处理的技术经济评价：聚合物超滤膜与陶瓷超滤膜

本文对陶瓷和聚合物管状膜超滤旧机油进行了综合试验和技术经济评价。使用KUFE陶瓷管状膜（ceramic Filter LLC）和F1聚合物管状膜（vladiporor R&D Center）进行了实验室和中试规模的研究。陶瓷膜的最佳温度和压力分别为383 K（110℃）和0.4 MPa，聚合物膜的最佳温度和压力分别为343 K（70℃）和0.4 MPa。提出了一种工业装置布置方案，采用膜单元分段和泵的选择来维持湍流，并尽量减少污染。陶瓷膜比聚合物膜表现出更高的比生产力（0.014 m3 m - 2 h毒血症）（0.006 m3 m - 2 h毒血症）。尽管聚合物膜系统的通量较低，但由于资本和运营支出显著降低，在最大吞吐量下，聚合物膜系统的成本效益提高了20%。废旧机油的超滤处理成本在20000 - 25000卢布/立方米（250-312美元/立方米）之间，与新鲜II类基础油的成本（70000卢布/立方米，850美元/立方米）相比，在经济上具有吸引力。

期刊介绍： Russian Journal of Applied Chemistry (Zhurnal prikladnoi khimii) was founded in 1928. It covers all application problems of modern chemistry, including the structure of inorganic and organic compounds, kinetics and mechanisms of chemical reactions, problems of chemical processes and apparatus, borderline problems of chemistry, and applied research.
