渣油泵Residual oil gear pumpConveying viscosity 380cst

原油经减压蒸馏所得的残余油。又称减压渣油。有时将从常压蒸馏塔底所得的重油称为常压渣油。色黑粘稠，常温下呈半固体状。其性质与原油性质有关。在石油炼厂中，渣油常用于加工制取石油焦、残渣润滑油、石油沥青等产品，或作为裂化原料。在石油化工生产中，渣油可通过部分氧化法生产合成气或氢气，或作为蓄热炉裂解制乙烯的原料。渣油另一重要用途是用作燃料油。

The residual oil obtained from vacuum distillation of crude oil, also known as vacuum residue. Sometimes, the heavy oil obtained from the bottom of the atmospheric distillation column is referred to as atmospheric residue. It is black, viscous, and semi-solid at room temperature, with properties related to those of crude oil. In petroleum refineries, residue oil is commonly used to produce products such as petroleum coke, residual lubricating oil, and petroleum asphalt, or as feedstock for cracking. In petrochemical production, residue oil can be processed via partial oxidation to produce syngas or hydrogen, or serve as feedstock for thermal cracking to produce ethylene. Another important use of residue oil is as fuel oil.

渣油的温度和粘度参数因类型和加工工艺不同而有所差异，以下是关键信息：

温度与粘度关系

渣油的储存和泵送需控制温度以降低粘度。通常储存温度需高于倾点10℃以上（约40-50℃），泵送时建议80℃左右。若需雾化燃烧，温度可能进一步升高。

具体粘度数据

减压渣油：100℃运动粘度约662.3 mm2/s，密度1.0121 g/cm3。

高黏度渣油：100℃运动粘度＞1000 mm2/s，属于高黏度残渣油。
