原油經減壓蒸餾所得的殘余油。又稱減壓渣油。有時將從常壓蒸餾塔底所得的重油稱為常壓渣油。色黑粘稠，常溫下呈半固體狀。其性質與原油性質有關。在石油煉廠中，渣油常用于加工制取石油焦、殘渣潤滑油、石油瀝青等產品，或作為裂化原料。在石油化工生產中，渣油可通過部分氧化法生產合成氣或氫氣，或作為蓄熱爐裂解制乙烯的原料。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.

渣油的溫度和粘度參數因類型和加工工藝不同而有所差異，以下是關鍵信息：

溫度與粘度關系

渣油的儲存和泵送需控制溫度以降低粘度。通常儲存溫度需高于傾點10℃以上（約40-50℃），泵送時建議80℃左右。若需霧化燃燒，溫度可能進一步升高。 

具體粘度數據

減壓渣油：100℃運動粘度約662.3 mm2/s，密度1.0121 g/cm3。 

高黏度渣油：100℃運動粘度＞1000 mm2/s，屬于高黏度殘渣油。 

重質燃料油：黏度范圍50-2000 mm2/s，密度0.94-1.06 g/cm3。

The temperature and viscosity parameters of residue oil vary depending on the type and processing method. The key information is as follows:

The relationship between temperature and viscosity

The storage and pumping of residual oil require temperature control to reduce viscosity. The storage temperature should typically be at least 10°C above the pour point (approximately 40-50°C), while pumping is recommended at around 80°C. For atomization combustion, the temperature may need to be further increased.  ?

Specific viscosity data

Deasphalted oil: kinematic viscosity at 100°C approximately 662.3 mm2/s, density 1.0121 g/cm3.  ?

High-viscosity residue oil: kinematic viscosity at 100°C > 1000 mm2/s, classified as high-viscosity residual oil.  ?

Heavy fuel oil: viscosity range 50-2000 mm2/s, density 0.94-1.06 g/cm3.
