Continuous Distillation
This equipment demonstrates a process for separation of a mixture (one soluble in another) of two liquids of different boiling points.
The unit consists of boiler, two distillation columns, condenser, reflux tank, top product tank, feed tanks with feed pump, feed preheater, bottom product tanks, measuring instruments, and other accessories.
An initial feed is added to the boiler where the vapor with higher concentration of the lower boiling point component rises in the distillation column. The vapor leaves the top and is condensed in the condenser and collected in the reflux tank. Part of the condensate in the reflex tank is fed back to the top of the column where heat exchange is taken place with the rising vapor. This results in the vapor phase being richer in the lower boiling point component, and the liquid phase being richer in the higher boiling point component. The liquid phase moves down to the boiler.
The feed is pumped from feed tanks, preheated in a heat exchanger, before delivery to the distillation column. The feed is partially evaporated in the column on its way to the bottom where it is heated to boiling.
The hot mixture in the boiler is rich in higher boiling point components is used to preheat the feed and collected in the bottom product tanks.
Two columns, sieve plate column and packed column with Rasching rings, can be interchanged simply by valve control. Lagging is provided for boiler, sieve column, condenser, and preheater.
The unit is installed on a stainless steel frame.
Instruction manual is also included.

Chemical Engineering EquipmentGas Absorption Collumn
This equipment is for demonstration of gas absorption principles.
The unit consists of two packed absorption columns, one on top of another. The two columns are held together by steel frame and are packed by Raschig glass rings. A centrifugal pump draws a liquid from a feed tank underneath the column and delivers to the top of the column where it falls down through the packing and to the storage tank. Flow rate is indicated on a variable area flow meter.
A gas to be absorbed such as carbon dioxide is drawn from a pressure cylinder through a flow meter and is mixed with an air stream supplied through an air blower. Air flow rate is measured by a flow meter. The mixed gas enters the column at the bottom of the column and rises up to the top.
Pressure tappings and gas sampling points are provided at the bottom, middle and top of the column to measure pressure drops by manometers. Carbon dioxide content is determined by a Hempl apparatus. All instruments are mounted on a panel.
Instruction manual is also included.

- Methods of gas and liquid analysis.
- Determination of mass transfer coefficient.
- Mass balancing over the packed absorption column.
- Hydrodynamic characteristics of a packed column.

Chemical Engineering EquipmentFluidization and Heat Transfer
This bench top equipment is for studying the behavior of a fluidized bed and heat transfer coefficient of a hot surface in a fluidized bed.
The unit consists of a glass cylinder with a bottom chamber and a top assembly. The bottom chamber has as a built-in air distributor. The distributor can be replaced by a locally designed one for students and other investigations. The top assembly consists of an air filter and a heating element, temperature probes and a pressure probe. The glass cylinder assembly is attached to a panel through the top assembly and can be easily removed and installed.
The glass cylinder is partially filled with granular bed material. Air is supplied to the bottom chamber. The air fluidizes the bed material and escapes to the atmosphere through the top filter.
A small air compressor is provided. The air flow rate is measured by a rotameter. A heating element is provided in the glass cylinder. Temperature probes are provided for measurement of heating element surface, fluidized bed and air inlet to the bottom chamber. A water manometer measures pressure drop in the fluidized bed. The heating element, temperature probes and pressure probe can move up and down at any position in the glass cylinder.
Safety features include overheating and overpressure. A second temperature probe on the heating element limits heating element maximum temperature by a controller. A pressure relief valve is provided at inlet airline to limit maximum pressure in the glass cylinder due to blocked filter.
Instruction manual is also included.
TYPICAL EXPERIMENTS- To study the behavior of a fluidized bed for various types of granular materials.
- To study changes in pressure drop vs air flow for various granular materials, both pack and fluidized beds.
- To study the effect of superficial velocity, depth of immersion, and granular size on the surface heat transfer coefficient by a hot surface in a fluidized bed.
- To investigate the effect of distributor design on the bed behavior.
- To demonstrate separation by particle size and density.
