Introduction

  • The purpose of an oil refinery is to transform Crude Oil which is a non-uniform mixture of hydrocarbon molecules, into fuel and chemical products that meet the needs of the consumer.

Significant Concepts

  • Refineries differ in their level of complexity. There are many different types of refining processes, different types of crude oils, and so each refinery is unique
  • A standardised measure of the complexity of a refinery is the Nelson Complexity, the more units a refinery has, the more capabilities it possesses, the higher Nelson Complexity number it is assigned
  • Refineries that have no cracking units are referred to as Hydro-skimming Refineries. They typically have Nelson Complexities of 2-3

Refining Processes

  • Petroleum refining processes and operations can be separated into five basic areas:

Fractionation

Conversion

Treatment

  • Treatment Processes to prepare hydrocarbon streams for additional processing and to prepare finished products.

Formulating and Blending

  • Formulating and Blending is the process of mixing and combining hydrocarbon fractions, additives, and other components to produce finished products with specific performance properties.
