OVERVIEW

            The purpose of this unit is to examine reactor princi­ples, basic reactor design, various types of reactors (stirred tank, tubular, and catalytic bed), plant batch and continuous reactor operations, and reactor applica­tions. Basic operator responsibilities  for reactor operations are also covered.

OBJECTIVES

Reactor Principles

·          Describe the effects of temperature and pressure on reactor operations.

Basic Reactor Design

·          Describe the basic components of a reactor.

·          Describe auxiliary equipment commonly associated with a reactor.

Stirred Tank Reactors

·          Describe batch and continuous stirred tank reactors.

·          Describe the general operation of a batch stirred tank reactor system.

·          Describe the general operation of a continuous stirred tank reactor system.

Tubular Reactors

·          Identify a tubular reactor.

·          Describe the general operation of a jacketed tubular reactor.

·          Describe the general operation of a fired-tube reactor.

Catalytic Bed Reactors

·          Describe the general operation of a fixed bed reactor.

·          Describe the general operation of a fluidized, moving bed reactor.

Reactor Operations

·          Describe general operator responsibilities associated with reactor system operation.
