Chemical Engineering EquipmentBatch Distillation Unit
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, vacuum pump, measuring instruments, and other accessories.
The liquid mixture is added to the boiler where the mixed 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 the reflux tank. Part of the condensate in the reflux tank is fed back to the top of the column where heat exchange is taken place with the rising vapor. This results in vapor phase being richer in lower boiling point component, and the liquid phase being richer in higher boiling point component. The liquid phase moves down to the boiler. Thus, the mixture in the boiler is richer in the higher boiling point component with time.
Two columns, sieve plate column and packed column with Rasching rings, can be interchanged simply by valve control. Lagging is provided for reboiler, sieve plate column, and condenser.
The unit is installed on a stainless steel frame.
Instruction manual is also included.
TYPICAL EXPERIMENTS- Comparison of plate column and packed column performance
- Pressure drop across column vs boil up rate
- Column efficiency vs boil up rate at total reflux
- Top product composition vs time at constant reflux ratio
- Manual control of reflux ratio
- Plate to plate temperature profiles
- Mass balance across the system

Chemical Engineering EquipmentContinuous 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.

Chemical Engineering EquipmentDeep Bed Filter Column
The deep bed filter is a demonstration unit for treatment of water with suspended particles by sand filtration.
The unit consists of a filtration column is fitted with vertical row of pressure tapping points on one side and similar sampling points on the other side. Both ends of the column are closed with flanges for liquid inlet and outlet. A pump delivers raw water from the raw water tank to the top of the column. Suspended particles are trapped in the sand filter as water flow down through the column to the bottom via filter. The treated water is collected from the bottom in a treated water tank. Hoses connect pressure from the tappings along the side of the column to a manometer bank. Samples of raw water is collected from the sampling points on the side of the column. A manometer bank is provided for measurement of pressure along the column.
Overtime more particles are deposited in the filter which increases the pressure drop across the filter and flow rate decreases. Backwashing is required using treated or clean water and pressure drop is reduced again. Required pipings are provided. The filter unit is on a steel frame.
Instruction manual is also included.
TYPICAL EXPERIMENTS- Understanding the principles of depth filtration by sand filter.
- Measurement of filter differential pressure vs flow rate.
- Observation of pressure drop with time.
- Measurement of suspended particles at different height.

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.

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.
