The major factors affecting the pickling rate are scale thickness, compactness, and the oxide structure, especially the amount and continuousness of hematite.

经归纳后发现影响锈皮酸洗难易度之内在因素主要有三：(1)锈皮厚度、(2)锈皮致密性、(3)锈皮组成，尤其是Fe2O3层的量及连续性。

It is used extensively in industrial processing of metals and concentrating of some ores; in boiler scale removal, food processing, metal cleaning, and pickling; and as a chemical intermediate, laboratory reagent, and alcohol denaturant.

工业上广泛使用盐酸来处理金属和提炼某些矿物，或用于锅炉除垢、食品加工、金属清洁和酸洗，还可作为化学中间体、实验室试剂以及酒精变性剂。

It is used extensively in industrial processing of metals and concentrating of some ore s; in boiler scale removal, food processing, metal cleaning, and pickling; and as a chemical intermediate, laboratory reagent, and alcohol denaturant.

工业上广泛使用盐酸来处理金属和提炼某些矿物，或用于锅炉除垢、食品加工、金属清洁和酸洗，还可作为化学中间体、实验室试剂以及酒精变性剂。

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。
