Color of hydrocracking tail oil
Thread Content
Everyone: What color is the hydrocracking tail oil in your units? Could you provide the specific metrics? Thank you first.
Yellow, mainly used for boiling range and PONA value
Green: mainly engaged in BMCI; distillation range is also carried out if necessary
Light yellow, used to determine the boiling range and aromatic content.
Pale yellow, used for analyzing boiling range, group composition, and aromatic content.
The device was white when it first started operating, but it is now light yellow. Tail oil analysis includes boiling range, BMCI value, sulfur, and nitrogen; sometimes the family composition is analyzed, while other parameters are not analyzed very often.
7# net2002163: White in color; the main parameter to be analyzed is the boiling range. If it is to be used as a base oil for lubricants, viscosity, flash point, etc. also need to be analyzed
Yellow is mainly related to the BMCI value, as it is used as a raw material for ethylene
Yellow color, density, boiling point, and BMCI values
