Batch Process Systems (APO03)

Learn about batch process steps, types, and operation as well as batch process control strategies.

Prerequisites

This lesson is designed for participants familiar with process control. A knowledge of standard symbols used in process control diagrams, PID control systems, and various process control strategies is also recommended.

Description

This lesson introduces industrial batch process systems. The lesson includes batch process steps, types, and operation as well as batch process control strategies.

Objectives

Describe the operational differences between batch and continuous processes. Identify components, functions, and control requirements of a batch process. Describe control variables and strategies for temperature control. List batch process steps in correct operational sequence. Describe the purpose of polymerization. Describe how the effects of disturbances and load changes can be minimized. Describe how the control system would respond to an increase in reaction rate in an exothermic batch process. Describe the heat transfer principles that contribute to batch process control. State the advantages of using a closed system of heating and using a heating or cooling coil. Describe the operation of a single feedback control loop and a cascade control loop. Describe the operation and control of a batch process using split range valves. Describe how pressure can be controlled.
