Feedstock and products of diesel and gasoline hydrogenation units
Thread Content
The unit is a diesel hydrogenation plant; its feed materials are gasoline and diesel, as well as coker gasoline and regular diesel. The flow rate of gasoline is 30 tons per hour, while that of diesel is 20 tons per hour. Yet, the output from the distillation tower is approximately 40 tons per hour for refined diesel and around 10 tons per hour for gasoline. Looking at the raw materials, there’s plenty of gasoline; shouldn’t the resulting products also be mostly gasoline? Please share your thoughts, thank you
Depending on the raw materials used in processing, the types and quantities of products obtained from the distillation tower will also vary. Due to the different boiling point ranges of gasoline and diesel during the fractional distillation process, gasoline and diesel are produced at different temperatures. Furthermore, the hydrogenation process may alter the composition and properties of the feedstock, affecting the separation efficiency of the distillation column and also leading to changes in product yield and proportions. Therefore, just because there is more gasoline in the raw materials does not necessarily mean that the final product will also contain more gasoline. -
If the coker gasoline constitutes the entire gasoline range, I don’t think that’s likely; take a look at what the final boiling point of your coker gasoline is.
Is the boiling range of coker gasoline similar to that of diesel? In reality, gasoline doesn’t have such a wide boiling range
