The relationship between the residue carbon of atmospheric and vacuum distillation units and that of crude oil
Thread Content
Is there a necessary relationship between the desulfurization residue carbon of atmospheric and vacuum distillation units and that of crude oil? The residual carbon of crude oil is around 3.6, while that of the slag-reducing agent is 14.0. Please provide guidance
To give an example, if 3.6% of crude oil is carbon residue, that means there are 3.6 grams of carbon residue. After normal pressure and vacuum processing, 25.71 grams of alkaline residue remain in 100 grams of crude oil. Since carbon residue consists of heavy components that hardly evaporate, its amount remains at 3.6 grams; therefore, its proportion increases to 14%. If X represents the amount remaining after vacuum processing for 100 grams of crude oil, then 100×3.6% = 14%×X, which gives X = 25.71
