  1. Question 1

    What are the main refinery categories?
    • Simple, Semi-complex and Complex refining.
    • Basic and Advanced refining.
    • Primary and Secondary refining.
    • Low and High complexity refining.

  2. Question 2

    Thermal cracking: What is the main aim of this conversion process?
    • It is a method to increase the viscosity of the feedstock.
    • It aims to enhance the aromatic content of the feedstock.
    • It is used to separate different fractions of the feedstock.
    • It is a process designed to reduce the molecular size of a portion of the feedstock by the application of heat.

  3. Question 3

    What are the three major applications of the thermal cracking process?
    • Visebreaking, Thermal gas oil production and Coking.
    • Hydrocracking, Catalytic reforming and Distillation.
    • Alkylation, Isomerization and Dehydrogenation.
    • Cracking, Polymerization and Gasification.

  4. Question 4

    What does fuel oil from a fully complex refinery consist of?
    • Visebreaken residue (i. e. combination of residue and gas oil from the thermal cracker) diluted with cycle oil, cycle oil slurry and smaller amounts of other distillates.
    • Crude oil and natural gas.
    • Only gas oil and kerosene.
    • A mixture of gasoline and diesel.

  5. Question 5

    What is the main difference between ISO 8217-1987 and ISO 8217-1996 for MFO 380, RMG 35?
    • New limits: Aluminium plus silicone (mg/kg) max. 8.0 Total sediment, potential, % (m/m), max. 0.10.
    • Increased viscosity limits and lower flash point requirements.
    • Changes in sulfur content and density specifications.
    • Introduction of new additives and performance standards.
