General Overview
THIS INSTRUCTION MANUAL SHOULD BE USED IN CONJUNCTION WITH THE
MANUAL SUPPLIED WITH THE CEXC COMPUTER CONTROLLED CHEMICAL
REACTOR SERVICE UNIT.
This Manual provides the necessary information for operating the equipment in
conjunction with the CEXC Computer Controlled Chemical Reactor Service Unit, and
for performing a range of Teaching Exercises designed to demonstrate the basic
principles of Chemical Reactors theory and use.
The continuous stirred tank reactor in the form of either a single tank or (more often)
tanks in series, is used widely and is particularly suitable for liquid phase reactions. It
is particularly used in the organic chemicals industry. Advantages include consistent
product quality, straightforward automatic control and low manpower requirements.
The Armfield CEM MkII Continuous Stirred Tank Reactor is specially designed to
allow detailed study of this important process. It is one of five reactor types which are
interchangeable on the Reactor Service Unit (CEXC), the others being CET MkII -
Tubular Reactor, CEB MkIII – Transparent Batch Reactor, CEY Plug flow reactor and
CEZ Laminar Flow reactor.
Reactions are monitored by conductivity probe as the conductivity of the solution
changes with conversion of the reactants to product and by temperature.
