Residue hydrocracking and fractionation
Thread Content
What does HAGO side line mean? The vacuum tower is HVGO. What does all this mean? There’s also an AGO
One is atmospheric pressure paraffin oil and the other is reduced pressure paraffin oil
In the distillation composition of crude oil, the fraction obtained at temperatures up to 200°C (180°C) is referred to as the gasoline fraction, or light oil, naphtha； The fraction ranging from 200°C to 350°C is known as the coal diesel fraction, or atmospheric gas oil – abbreviated as AGO ； The fractions ranging from 350°C to 500°C are referred to as lubricating oil fractions, or vacuum gas oil – abbreviated as VGO ； (Compared to the fractions at temperatures above 500°C, this fraction is also known as atmospheric residue – abbreviated as AR; whereas the fractions at temperatures above 500°C are called vacuum residue – abbreviated as VR.) ；
What are those stress-relieving LVGO and HVGO called?
Is it the initial boiling point or the final boiling point, for gasoline?
Atmospheric pressure gas oil – abbreviated as AGO； Reduced pressure gas oil – abbreviated as VGO; H indicates that it has been hydrogenated.
