Description
CEM-MKII Continuous Stirred Tank Reactor (CSTR) Didactic Equipment Vocational Education Equipment Chemical Engineering

DESCRIPTION
The CEM-MKII Continuous stirred tank reactor is probably the most common type of reactor found in industry. The CEM-MKII is a small-scale demonstration version for educational use. It is extremely flexible in use and can be used for both continuous and batch reactions.
The volume of the reactor is adjustable to between 0.4 and 1.5 litres using an adjustable standpipe allowing different hold-up volumes and residence times to be investigated. The temperature probe and conductivity probe (supplied with the CEXC) can be positioned in the reactor vessel.
A stainless steel coil is used for temperature control of the reactor from the hot water supply on the CEXC (or cold water from such as the CW-17 Chilled Water Circulating Unit).
A variable-speed mixer/agitator is included (controlled by the CEXC) together with baffles to improve the mixing.
The CEM-MKII uses the saponification reaction and uses conductivity to measure the progress of the reaction. It also uses a step input change experiment to obtain the residence time distribution.


EXPERIMENTAL CONTENT
To find the reaction rate constant in a Continuous Stirred Tank Reactor
Effect of varying the temperature on reaction rate
Effect of varying the reactor volume
Effect of varying the mixing speed
Effect of varying the feed rate
Effect of varying the flow rate on conversion
Determination of the Residence Time using tracer techniques
To determine the effect of inadequate mixing on the reaction rate
