National Exam 04-Chem-B6, Petroleum Refining and Petrochemicals — December 2016. 3 hours, OPEN BOOK (any non-communicating calculator permitted). Per the exam notes, FIVE questions constitute a complete paper — Question 1 is multiple-choice and Questions II–V require essay-format answers of equal value (10 marks each); clarity and organisation are explicitly marked. This paper contains exactly five questions, so all five are answered here in full. The exam is almost entirely qualitative; the only computed quantities are the two standard crude-characterisation relations used to justify the multiple-choice answers.
