I’ve heard that some factories and refineries mix solvent oil into gasoline in order to increase profits. What impact does mixing solvent oil into gasoline have on the quality of the gasoline? Basic knowledge of solvent oils
There should be one. We don’t have one here
It can be incorporated. 200# and 120# solvents can be mixed into gasoline, and even naphtha can be added. It’s just that the octane number of the solvent oil is low, so high-octane components need to be added.
It can be adjusted by adding some flavor enhancers, MTBF, etc.; however, the thiols and other such substances need to be dealt with.
4# wgfhao: The addition of solvent oil reduces the octane rating of gasoline; it can be used as a catalytic terminator in gasoline.
This forum has information on solvent oils; search for it by yourself
Specifically, the solvent oil processing processes fall within the scope of the gasoline processing process; since the gasoline processing process has a wider range, more gasoline can be mixed during distillation, which affects the quality of the solvent oil.
Solvent oils generally have a very low octane rating, making them unsuitable as components for blending into automotive gasoline. Of course, if there is a large margin in gasoline octane rating, it is also possible to add some solvent oil.
It can be added, but the amount depends on the properties of the raw material.
Adding solvent oil to gasoline is not something new; generally, a certain proportion of solvent oil is added according to sales requirements. You can take a look at “Oil Blending Technology”.
Solvent oils are classified by boiling range into 60# solvent oil, 120# solvent oil, 200# solvent oil, and heavier grades such as 150#. They are usually obtained through atmospheric distillation (with some also coming from reformation residue oil), and their octane rating is generally low. Solvent oils do not sell well in the market, as quantities purchased are usually small. Atmospheric distillation units can produce large volumes of these oils, and those with the capability can modify them. Most small refineries sell them after blending them with cracked gasoline. The octane rating of straight-run gasoline (solvent oil) is very low; in the past it was used to blend into 74# gasoline, with a high blending ratio. After 74# gasoline was banned, it was generally used to blend into 90# gasoline (blending it into 93# gasoline was difficult). The typical blending ratio is below 1:3, and a significant amount of anti-knock agents must be added. Attention must also be paid to the metal content during blending
