Wetted Wall Gas Absorption Column

Code: CES

CES demonstrates the absorption of oxygen from air into deoxygenated water, as an example of liquid film controlled absorption. The liquid-film mass transfer coefficient can be determined at various mass flow rates of water.

Catalytic Reactors

Code: CEU

The Armfield Catalytic Reactors unit (CEU) utilises the sugar inversion reaction (Sucrose ➞ Glucose + Fructose) to study the performance of packed-bed chemical and biological catalytic reactors. A colorimetric assay is used to determine the degree of conversion using an optical sensor. Assays may be automated using optional flow injection analysis.

Computer Controlled Chemical Reactor Teaching Equipment

Code: CEXC

The Armfield CEXC family is a range of chemical reactors specifically developed for the teaching and demonstration of chemical reactor capabilities to chemical engineering students. Real chemical reactions take place within the reactors, and Armfield have developed a number of representative reactions which are easy and safe for students to use in the laboratory environment.

Fixed and Fluidised Bed Apparatus

Code: CELMkII

The CELMkII is designed to facilitate the study of flow through fixed and fluidised beds of solid particles.

 

Solids Handling Study Bench

Code: CENMkII

The CEN comprises a variety of items which introduce different aspects of solids behaviour. The characteristics of the flow of solid materials are relevant to many process industries, particularly in handling powders, pellets, crystals and aggregates.

Gaseous Diffusion Coefficient Apparatus

Code: CERaMkII

Apparatus for investigation of mass transfer and gaseous diffusion has traditionally used a capillary tube in a hot water bath, with a travelling microscope used to measure the rate of diffusion over a period of time. Although capable of giving good results, this type of apparatus was not without its disadvantages, particularly ease of use.

Distillation Columns

Code: UOP3

  • Distillation Engineering Teaching Equipment. The UOP3 laboratory-based distillation columns allow safe hands-on practical training for student engineers and plant operators. Available as either a continuous distillation column or a batch-only version for teaching the fundamentals.

Laboratory Steam Generator

Code: UOP10

The UOP10 is an advanced boiler, providing a constant, steady supply of steam. The compact unit requires only connection to water and electrical supply for operation.

Filtration Unit

Code: UOP12

The UOP12 demonstrates the principles of batch filtration, using a fully functional plate and frame filter system. A continuous, tangential flow microfiltration unit using a hollow fibre filtration cartridge is available as an option.

Fixed Bed Adsorption Unit

Code: UOP15

The UOP15 demonstrates the adsorption of a solute, carbon dioxide, from a binary gas mixture onto the surface of a solid adsorbent, activated carbon. Adsorption and desorption processes take place within a fixed bed adsorption column.

3-Phase Horizontal Separator

Code: UOP30

The Armfield 3-Phase Horizontal Separator is a small-scale unit capable of demonstrating the principles and operation of gravity separation and the effect of viscosity, flow characteristics and density difference on separation. The Armfield UOP30 comes with two horizontal separator configurations making the UOP30 a versatile teaching unit.

Modular Evaporator Family

Code: UOP20X

The UOP20X is a modular system of evaporators for teaching chemical engineering. Using the various modules a wide range of configurations can be implemented: rising or falling film; single or double effect; forward, backward or parallel feed. The evaporators are fully
computer compatible, supplied with educational software including process control and data logging facility.

Solid/Liquid Extraction Unit

Code: UOP4MkII

The UOP4-MkII is a laboratory-scale solid/liquid extractor system for teaching the fundamentals of this important unit operation to chemical-engineering students. The equipment utilises a sophisticated, continuous feed, counter-current flow, multiple-stage, rotary extractor system of the type frequently seen in industrial applications.

Liquid/Liquid Extraction Unit

Code: UOP5MkII

Liquid/liquid extraction is a valuable process where separation of one or more components of a liquid mixture is required. The UOP5MkII demonstrates this process in the laboratory so that students may gain a thorough understanding of the technique.

Basic Water Cooling Tower

Code: UOP6MkII

The Armfield Computer Controlled Water Cooling Tower has been designed to give students an appreciation of the construction, design and operational characteristics of a modern evaporative cooling system. The unit is also an excellent example of a specialized heat exchanger, where two streams of fluid flow (water and air) are brought into direct contact and in which there is a mass transfer from one stream to the other.

 

Gas Absorption Column

Code: UOP7MkII

The Armfield Gas Absorption Column has been designed to demonstrate the principles of gas absorption, and to provide practical training in the operation of a gas absorption plant.

Computer Controlled Tray Dryer

Code: UOP8MKII

This small-scale benchtop tray dryer dries solids by passing a stream of hot air over trays of wet material, a method commonly used in industry. It is applicable to the unit operations laboratory and also to food technology education and research.

Crystallisation Unit

Code: UOP14MkII

The UOP14MkII enables laboratory demonstration of crystallisation, where the separation of one or more components of a liquid is required. The unit demonstrates an industrially important type of crystallisation, solution cooling crystallisation.
