7.3. Coker naphtha is hydrotreated to remove of the sulphur, of the nitrogen and all the olefins. Sulphur is present as thiophene and nitrogen as pyrrole. The naphtha has the following properties: Specific gravity: 0.763 , sulphur: , nitrogen: , propylene: , butanes: and butadienes: . (a) Find the chemical hydrogen requirement for one barrel of naphtha. (b) Make a material balance around the hydrotreater and find the hydrotreated naphtha API.

Expert Answer


To find the chemical hydrogen requirement for one barrel of naphtha, we need to calculate the amount of hydrogen required to remove sulfur and nitrogen from the naphtha.
(a) Chemical hydrogen requirement:
Calculate the molecular weight of hydrogen:
Hydrogen   
Calculate the molecular weight of sulfur:
Sulfur   
Calculate the molecular weight of nitrogen:
Nitrogen  
Calculate the moles of sulfur in one barrel of naphtha:
Moles of sulfur = (sulfur content in wt% /   ) * (barrel weight / naphtha specific gravity) / molecular weight of sulfur
Moles of sulfur
