The reduced crude may then be processed by vacuum or steam distillation to separate the high-boiling lubricating oil fractions without the danger of decomposition, which occurs at high (>350℃, 660℉) temperatures.

由此，我们有可能获得石油产品，这些产品包括从蒸馏塔顶部得到的气态物质，包括比重较大的渣油或称“残渣”(一般而言挥发性较差)，以及从蒸馏塔中部得到的比重较小的其他相应物质。
