4. Distilling

Question 1

■ Feedstock and output of distilling column?
■ Cut Points of Fractures?
■ Futher Processing (Product Disposition)?
■ Farenheit to Celsius formula?

Answer 1

Feedstock - Curde Oil
│
Output:
▪ Butane (C4H10) and lighter [<90ºF] — Gas Processing
▪ Straight Run Gasoline (SRG) [90º-220ºF] — Motor Gasoline Blending
▪ Naphta [220º-315ºF] — Cat Reforming
▪ Kerosene [315º-450ºF] — Hydrotreating
▪ Light Gas Oil (SRLGO) [450º-650ºF] — Distillate Fuel Blending
▪ Heavy Gas Oil (SRHGO) [650º-800ºF] — Cat Cracking
▪ Straight Run Residue [800º+] — Flashing

ºC=(ºF-32)*5/9
