Dalian International Trade in the United States and United Microelectronics Co., Ltd. At the same time in a competitive wholesale prices and sales of series of Mobil lubricants, 76 / Conoco lubricants and the United States, Chevron's Caltex brand lubricants and other products imported.

大连美联华国际贸易有限公司同时以具有竞争性的价格批发和销售系列美孚润滑油、76 / Conoco润滑油和美国雪佛龙公司的加德士润滑油等进口品牌产品。

Finally, two short-path distillation processes and one falling film evaporator are applied in the regeneration of waste lubricating oil. In the test, the diesel oil, gasoline and lubricating oil are distilled respectively, while the gelatinoid materials, asphaltene and carbon residue remain in the draft. The regenerative lubricating oil accords with the standards of base oil. And the recovery efficiency is up to 75 percent. The technology used in the test doesnt comprise processes like pickling and alkali neutralization, which would cause secondary pollution like acid draff and sulfur dioxide and so on. As a result of this, our technology is friendly to the environment.

最后，利用一级薄膜蒸发和两级短程蒸馏工艺对废润滑油进行了再生回收工业应用试验，将柴油、汽油等轻油以及润滑油馏分分别蒸馏出来，而大部分胶质、沥青质、碳垢存在于残渣中，试验得到的再生润滑油符合基础油的标准，回收率达到75％，达到废润滑油再生的目的；同时再生过程中没有酸洗、碱中和等工序，不产生酸渣、二氧化硫等二次污染，是一种清洁环保的废润滑油再生工艺。
