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.
O B J E C T I V E S
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.
