总部位于美国堪萨斯州的Universal润滑剂公司,使用“再回收”工艺回收废润滑油并将其加工成新产品。该工艺属于闭环工艺,是一种自给自足的体系。该公司每年加工4 000gal(1gal≈3.785L)以上废油,可生产出商标为“EcoClear”的API-Ⅱ类基础油。目前美国每年仅有约10%~15%的废油(约(1.3~2.0)×108 gal)被回收再利用。与采用原油加工的基础油相比,废油再生可节约89%的能耗,减少有害气体排放高达65%。
Universal Lubricant Corporation, headquartered in Kansas, USA, uses the “Recycled” process to recycle used lubricants and process them into new products. The process is a closed-loop process, is a self-sufficient system. The company processes 4,000 gal (1gal≈3.785L) of waste oil annually to produce API-Ⅱbasestock with the trademark “EcoClear”. At present, only about 10% to 15% of the used oil (about 1.3 to 2.0 × 108 gal) is recycled and reused in the United States each year. Compared with the crude oil processing base oil, waste oil regeneration can save 89% of energy consumption, reduce harmful gas emissions up to 65%.
