Total mark =75 Referring to the crude assay attached below and making use of class material, answer the following questions: 1) 1.a) What is the volume percentage of the cut boiling between 100 and 175C ? (10 marks) 1.b) Calculate the density of the cut boiling between 100 and 175C ? (15 marks) 2) To what type of distillation does cut 13 belong to? ( 2 marks) 3) What is the normal boiling point range of cut number 13 in C?(15 marks) 4) 4.a) Name two properties of the oil that determine its paraffinicity or aromaticity? Are these chemical or physical properties? Which one of these is usually available in the crude oil assay? ( 5 marks) 4.b) Is cut 3 of this crude oil more paraffinic or more naphthenic? (5 marks) 5) Does cut number 7 or cut number 5 have the higher sulfur content? Explain why ( 3 marks) 6) Calculate the mass of CCR in residue per volume of crude oil (20 marks) Page 1 of 2 DISTILLATION, BUREAU OF MENES ROUTINE METHOD Firat drea.
