Petroleum Chemistry is a course that addresses the chemical composition and physical properties of petroleum, methods of fractionation and analysis and the chemical basis for the most common refinery processes. It also provides and an overview of the products from oil refining. Some additional subjects will be included. These are typical unit operations and historical tendencies in the fields of petroleum processing.

After completing Petroleum Chemistry, students will be equipped with a basic understanding of the following:

  1. The overall chemical composition of petroleum, including the phase composition of generalized oil types
  2. Physical parameters for evaluation of oil quality
  3. Principles of major refining processes
  4. Methods of fractionation and analysis of crude oil and fractions
  5. World oil and gas resources
  6. Potentials and processes for production of renewable liquid fuels from biomass sources
  7. Important secondary unit operations


A basic understanding of chemistry is required.


 Students will be assigned 5 homework assignments, and 1 final exam.
