Description:

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:
  • Self-contained sieve plate distillation column unit including reboiler, condenser and reflux tank, suitable for use with flammable solvents and fully instrumented for batch operation.
  • Temperatures throughout the process including those on each and every sieve plate are monitored and displayed on a bench mounted control console, via a selector switch. The console also houses controls for the power supplied to the reboiler heater and for reflux ratio settings between 0 and 100%.
  • The console front panel connections enable the use of standard laboratory recorders and data loggers and of industry-standard PID and PLC controllers (not supplied).
  • A U-tube manometer is incorporated to measure pressure drop over the distillation column.
  • The 50mm diameter sieve plate column may be readily interchanged with a packed column supplied as an alternative.
  • A vacuum system enables operation at reduced pressures down to 200mbar(abs).
  • The unit is supplied completely assembled including lagging, and a comprehensive instruction manual describes commissioning, maintenance and instructional assignments.

Description

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.

  • Visualisation of mixing and flow patterns
  • Torque/power/speed characteristics of different impellors
  • Mixing of solid-liquid suspensions
  • Mixing using immiscible liquids

  • The flat blades are attached to a common mounting hub with a simple mechanism providing a precise blade angle. Seven different blade angles can be set for each blade size

Description

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.

Instructional Capabilities

  • Understanding the principles of packed-bed catalytic reactors
  • Mass balancing
  • Examination of steady and unsteady-state catalysis
  • Comparison of chemical and biological (enzymic) catalysis
  • Flow characterisation in a packed bed
  • Understanding the principles of flow injection analysis (FIA)

Overall Dimensions

  • Height: 0.60m
  • Width:  1.00m
  • Depth:  0.50m

Gaseous Diffusion Coefficient Apparatus


Description:
  • A small quantity of the volatile liquid to be investigated is placed in a capillary tube, which is positioned in a heated metal block. The block is heated by an electric cartridge
  • heater and kept at a constant temperature using an electronic control loop.
  • A stream of air is passed across the top of the capillary tube, with a stationary layer of air above the liquid surface, creating a partial pressure difference between the liquid surface and the flowing air stream. As vapour diffuses from the liquid into the air stream, the amount of liquid in the tube reduces and the phase boundary between the liquid and the air drops. Measurement of how this phase boundary changes with time enables the molar mass transfer rate to be determined.
  • A slot in the heater block enables the phase boundary to be observed using a high definition microscope. This micro-scope produces high definition images onto a standard windows computer (not supplied).
  • The software provided with this microscope includes highly accurate measurement and an automated time lapse facility (either as video or multiple still images).
Instruction Capabilities:
  • Direct measurement of mass transfer rates in the absence of convective effects
  • Use of gas laws to calculate concentration differences in terms of partial pressures
  • Use of Fick’s Law to measure diffusion coefficients in the presence of a stationary gas
  • Measurement of the effect of temperature on diffusion coefficients
  • Gaining familiarity with the use of laboratory instruments to achieve accurate measurements of data required for industrial process design
  • Investigation into diffusion coefficients of  alternative fluids

    Basic Water Cooling TowerSpecification:
    • Bench top unit to demonstrate operation of a forced draught cooling tower, comprising tower base with air circulation, water reservoir with heater and make-up tank, and a control console with recirculation pump and instrumentation
    • Supplied with one standard packed column, dimensions 150mm x 150mm x 600mm, comprising 10 plates giving 110m²/m³
    • Three additional columns are available as options for comparison (bare column, 7 plates and 18 plates)
    • The columns are manufactured from clear plastic to allow viewing of water flow through the system
    • The columns are easily interchangeable without the use of tools
    Description:

    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:
    • Maximum working temperature: 50°C
    • Centrifugal fan, maximum air flow: 0.06kg/s-1
    • Packed columns: 150mm x 150mm x 600mm high
    • Variable area flow meter: 0 – 50g/s-1 with control valve for water flow rate to packings
    • Temperature measurement using Type K thermocouple displayed on 199.9 digital meter to measure terminal water temperatures and wet and dry bulb air temperatures.
    • Inclined tube manometer: 0 – 40mm H2O to measure orifice differential pressure or packing resistance.
