Fluid Catalytic Cracking Operations

3.5 2 Reviews SKU: ROFCCO0CENDuration: 60 Minutes

A typical petroleum refinery includes many different units that are associated with a variety of processes. One of the important units in a refinery is a fluid catalytic cracking unit, or "cat cracker." This course describes the basics of fluid catalytic cracking operations, with emphasis on the equipment that is used, the process variables that are involved, and operator responsibilities.

Learning Objectives

  • Topic I: Introduction to Fluid Catalytic Cracking
  • • Describe the purpose and basic operation of a fluid catalytic cracking unit.
  • • Define the following terms: conversion, yield, and catalyst.
  • • Identify and describe the functions of the major pieces of equipment in a typical fluid catalytic cracking unit.
  • • Explain how the principle of heat balance applies to cat cracker operation.
  • Topic II: Catalysts and the Cracking Reaction
  • • Explain the role of the catalyst in fluid catalytic cracking operations.
  • • Define the terms "selectivity" and "activity" in relation to catalysts.
  • • Describe the cracking reaction and explain how it can be controlled.
  • • Define the terms "over-cracking" and "severity."
  • Topic III: Fluid Catalytic Cracking Reactors
  • • Identify and describe the function of risers in a typical fluid catalytic cracking unit.
  • • Describe the design and function of a typical fluid catalytic cracking unit reactor.
  • • Explain the process of recovering spent catalyst from a reactor and describe the equipment that is typically used.
  • Topic IV: Catalyst Regeneration
  • • Identify the major parts of a typical fluid catalytic cracking unit regenerator and describe the function of each part.
  • • Describe a typical process for handling the flue gas from cat cracking operations.
  • • Define the following terms: dense phase, dilute phase, afterburning, and snowballing.
  • • Explain what the color of a regenerated catalyst sample typically indicates.
  • Topic V: Fractionation
  • • Identify the major pieces of equipment in a typical fractionation system and describe the basic operation of the system.
  • • List the products typically obtained from a fluid catalytic cracking unit's fractionation system.
  • Topic VI: Catalyst Circulation
  • • Explain how catalyst circulation may be controlled.
  • • Describe two conditions that may result from improper catalyst circulation.
  • Topic VII: Process Variables
  • • Define the term "catalyst-to-oil ratio."
  • • Describe how yield, conversion, severity, catalyst-to-oil ratio, and charge rate are related.
  • • Describe how a change in product yield can affect other process variables.
