Exercise 6: Prediction of Visbreaking Yields A vacuum residue is fed into a coil visbreaker at a rate of 150lbh. it has an APi=12 and sulphur content of 5%. Assume 10 wt\% conversions. 1. Make a material balance for the visbreaker E. Calculate sulphur in the products ii. Calculate the API and SG of the products Additional information: Prediction of Visbreaking Yields Gas wt%=0.189825% Conv +0.677163 Gasoline wt W0=0.73821 \% Conv +0.260174 Residue we\% =0.146669(%Contv)22.20364496 Conv +98.677947 H2S in Gas wt\% =0.02023 consw +0.06043 whis Sy0.156 Gas oll wt =100 - Gas wtob - Gasoline wth - Residue wtoc - H. s wt % where Sf refers sulphar content in feed Sulphur in Visbsreaker Products S in H2S in Cas=(H2S3432) wt\%s S in Gasoline =0.260112w1wssf writes in Ges off =0.539924 wrysg S in Residue =S in Feed S in gasoline S in GOS in H2S where Sy refers sulphur content in feed Gravity of Visbreaking Products Gasoline API =0.262156 Conv +0.315121APff+56.83723 Gas oll API =0.052919% Conz +0.52228042APIf+12.9318914 Residue API=0.74621839 Conv +1.29131825APlf2.6831388 where APlf refer feeat APl grawity Additional Information: Specific heat of steam =2.13kJ/(KgC) Heat of carbon combustion =32,770kJ/Kg Heat of sulphur combustion 9300kJ/Kg
