The unit is a self-contained and fully instrumented distillation facility, suitable for practical laboratory work relevant to the teaching of unit operations. The equipment employs galvanically isolated intrinsically safe circuits and flameproof devices as appropriate, to enable safe distillation of standard test mixtures such as methylcyclohexane-toluene, methyl alcohol-water etc. The equipment consists of two interconnected units: a floor standing process unit and a bench-mounted control console.Specification:
The apparatus comprises a clear acrylic mixing vessel mounted on a stainless steel base. Above this is mounted a variable-speed electronic mixer with electronic torque measurement incorporated.
A set of PVC baffles can be fitted into the mixer with a simple screw mechanism to hold them in place. Under the stainless steel base is a storage compartment for the various small mixer components and the simple tools (hexagonal keys) required to change them. The larger mixer components are stored on pins behind the vessel.
The Rushton turbine impellor is a one-piece stainless steel fabrication with eight alternate upward and downward-pointing blades. The flat-blade impellor comes with six sizes of blade, each of which can be fitted in seven positions (vertical, plus 30/45/60 degrees leading and trailing edge). The blades are simple to configure and position accurately in place using a single screw. A propeller-type stirrer is also included for comparison.
The CEU unit introduces students to the fundamentals of packed-bed catalytic reactors. It is a benchtop unit available with either two or three reactor columns. Using two columns with a chemical catalyst allows a different particle size exchange resin to be used in order to study the effect of particle size on reactor kinetics. It is possible to use a third column to investigate biological catalysis, using the enzyme invertase, and compare this with chemical catalysis.

The Basic Water Cooling Tower is completely self-contained and includes both the simulated heating load and the circulating pump. It has much the same configuration as a full size force drought cooling tower, has the same characteristics and stabilizes quickly.
In this unit a fan is placed at the base of the tower to drive air upwards through the packing. Natural buoyancy assists the fan and helps dissipate the humid air from the top of the tower.
The packing in the cooling tower breaks the water into thin films or droplets which present a large surface area to the air stream and thereby assist the cooling process. The water is cooled largely by evaporation and, to a small extent, by direct contact cooling. Due to the evaporation of some of the water into the air stream, a continuous supply of fresh water must be added to the system. This ‘make-up’ is normally less than 5% of the cooling water flow rate. A float valve is provided to allow accurate measurement of ‘make-up’. When the cooled water falls to the load tank it is reheated before circulation.Technical Details:
