CHAPTER 16
SEPARATION MODEL
OBJECTIVES
• Apply the scientific principles associated with chemical separation processes
• Describe the operation of the separator 600 system
• List the composition of the separator feedstock.
• Draw the separator 600 system
• Identify the simple instruments used to operate the separator system
• Draw each of the control loops in the separator system and list typical set points.
• Operate the separator system
• Troubleshoot problems associated with the operation of the separator system.
REVIEW QUESTIONS
1. List the basic equipment associated with the separation unit.
