The application of blending FCC slurry from the bottom of fractionating column into feedstock of 240×104 t/a delayed coking unit was introduced.The results show that,when operating parameters are as same as the original operating mode,the yields of dry gas,LPG,gasoline,kerosene and diesel oil ...
(FCC slurry)extracted with furfurol at different temperatures and in solvent slurry ratio were determined.The optimum conditions for solvent extraction are 50 ℃ and 2:1 solvent slurry ratio.The selectivity calculated shows that furfurol is an excellent extraction solvent for separating FCC slurry....
slurry oil component. To meet this specification,refineries often add lighter, solids-free saleable products to dilute the slurry oil. This limits the total revenue capability of the refinery since No. 6 fuel oil is a relatively low price product.2. It can be used as a feedstock to a ...
An FCC is used to convert low value gas oils to valuable products like naphtha and diesel and slurry oil. It increases the hydrocarbon ratio by carbon rejection in a continuous process. In this process, a hot “fluid” catalyst at 538°C cracks heavy gas oil feed into gas/LPG, FCC petro...
