Improvement of the polishing unit for the recovery of base oil**

MemPore公司成立于2005年，旨在开发一种将脏油提炼成清洁、可重复使用的基础油的系统，并准备建立将废润滑油转化为有价值的清洁基础油的系统- 10升废油产生7升清洁基础油。这是第一次，废油可以在污染最小的情况下，从本地化的系统中净化，使用低能源，低资本和运营成本。MemPore的系统由三个自动化模块组成：预处理（除去水、燃料和乙二醇）；膜（类似于海水的反渗透）；最后是再生抛光。MemPore希望开发一种抛光装置，将其集成到其膜系统中，用于清洗废油。提出的创新主要集中在筛选各种吸附剂，并在方法上表征它们用于MemPore的废油抛光（吸附）装置。抛光装置的进料是膜装置的渗透流，而抛光装置的下游是实际的基础油和最终产品。这项研究和开发项目的主要目标是为MemPore的抛光装置收集和生产各种吸附剂的必要特性数据。这些数据有助于MemPore在其油抛光装置中增强和优化吸附柱。基本数据是吸附剂的吸附等温线，以及吸附剂从MemPore抛光装置的进料流中去除重金属和磨损成分的最大平衡容量。从初步的文献综述和MemPore的专业知识来看，建议从天然和活化的富勒土、天然和活化的膨润土、铝硅酸盐沸石13X和铝土矿开始。对吸附剂材料的研究将从详尽的文献和专利审查以及实验设计（DOE）开始，对吸附剂的分离性能进行实验预筛选。第二阶段进行实际吸附试验，生成吸附动力学和平衡等温线。将首先研究未处理和处理过的样品，以确定达到热力学平衡的时间。然后用它们来测定在不同温度下的平衡吸附能力。**

MemPore Corp. was founded in 2005 to develop a system that would refine dirty oil into clean, re-usable base oil and is ready to build systems that transform used lubricating oil into valuable clean base oil - 10 liters of used oil yields 7 liters of clean base oil. For the first time, used oil can be purified with minimal pollution, from localized systems, using low energy, and at low capital and operating cost. MemPore's System consists of three automated modules - pre-treatment (to take out water, fuel & glycol); membranes (similar to reverse osmosis of sea water); and final regenerative polishing. MemPore wants to develop a polishing unit that will integrate into its membrane system for cleaning used oil. The proposed innovation is mainly focused on screening various adsorbents and methodologically characterizing them for MemPore's used oil polishing (adsorption) unit. The feed for the polishing unit is the membrane unit's permeate stream while the polishing unit's downstream is the actual base oil and final product. The primary goal of this research and development project is gathering and producing the necessary characteristic data of various adsorbents for MemPore's polishing unit. This data helps MemPore to enhance and optimize the adsorption column in their oil polishing unit. The essential data are the adsorption isotherms of the adsorbents, and the maximum equilibrium capacity of adsorbents for removal of heavy metals and wear components from the feed stream of MemPore's polishing unit. From the preliminary literature review and MemPore's know-how, natural and activated fuller's earth, natural and activated bentonite, aluminosilicate zeolite 13X and bauxite are recommended to begin with. The research on adsorbent materials will start with conducting exhaustive literature and patent review as well as the design of experiments (DOE) for experimentally prescreening the separation performance of adsorbents. The second phase is performing the actual adsorption tests for generating the adsorption kinetics and equilibrium isotherms. The untreated and treated samples will be first studied to determine the time to come to thermodynamic equilibrium. Then they will be used to determine the equilibrium adsorption capacities at several different temperatures. **
