NEUTRALIZATION
(RCNEU)
Format: Video

O V E R V I E W
This unit introduces trainees to the principles of neutralization and neutralization reactions. After completing the unit, trainees should be able to describe what occurs during neutraliza¬tion reactions and how neutraliza¬tion reactions are used in industry. Trainees should also be able to describe operator responsibilities associated with batch and continuous processes that contain neutralization reactions.

Introduction
  • Define the terms acid, base (alkali), neutralization reaction, salt, and pH.
  • Identify what goes into a typical neutralization reaction and what comes out of the reaction.
  • List and explain three basic purposes of neutralization reactions in industry.

pH Control
  • Describe a typical system that controls the pH of a chemical product.
  • Describe a typical feed pH injection system.

Product Manufacturing
  • List and explain the purposes of the three steps in a typical soap manu¬facturing process.
  • List and explain the purposes of the two steps in a typical detergent manufacturing process.
  • Describe neutralization reactions associated with the manufacture of soaps and deter¬gents.

By-Product Neutralization
  • Explain how an alkaline catalyst can be neutralized and describe a typical ammonia neutralization process.

Neutralization in Batch Processes
  • Describe operator duties typically associated with a batch process containing neutraliza¬tion reactions.

Neutralization in Continuous Processes - Part 1
  • Describe typical operator duties that apply to a reactor startup in a process containing neutralization reactions.

Neutralization in Continuous Processes - Part 2
  • Describe typical operator duties that apply to a feed pH system in a continuous process.
