编辑同志: 在油品经营活动中,经常听到“三线油”、“润滑油料”、“润滑油基础油”这些名词。请问这些名词是什么意思? 辽河油田郝文郝文同志: 要回答你提出的问题,首先要从常减压蒸馏讲起。大家知道,在通常情况下,一壶水加热到100℃,水就沸腾了,无论再怎么加热,水都保持100℃继续蒸发,一直到水烧干为止。但在同样的条件下,把石油加热,使它保持连续蒸发状态,就必须不断提高加热温度。这是为什么呢?这是因为水是由氢、氧原子化合而成的化合物,它只具有一个100℃的沸点。而石油却不相同,它
Editor comrades: In the oil business activities, we often hear “three lines oil ”, “lubricant material ”, “lubricant base oil ” these terms. What do these terms mean? Hao Wen, Liaohe Oilfield Comrade Hao Wen: To answer your question, we must first talk about distillation from atmospheric and vacuum distillation. We all know that, under normal circumstances, a pot of water heated to 100 ℃, the water will boil, no matter how heated, water is maintained at 100 ℃ continue to evaporate, until the water until dry. However, under the same conditions, the heating oil, so that it remains a continuous evaporation of state, we must continue to increase the heating temperature. This is why? This is because water is a compound of hydrogen and oxygen atoms that has only a boiling point of 100 ° C. The oil is not the same, it
