CEXC – Computer Controlled Chemical Reactors Training Equipment

The Armfield CEXC Computer Controlled Chemical Reactors Teaching Equipment demonstrates the characteristics of the important types of chemical reactors.

The self-contained benchtop service unit is designed to provide services for up to five different chemical reactors. Continuous stirred tank reactor, Tubular reactor with plug, Transparent batch reactor, Plug flow reactor and laminar flow.

CEM-MkII – Continuous Stirred Tank Reactor

The continuous stirred tank reactor is used widely and is particularly suitable for liquid phase reactions. It is particularly used in the organic chemicals industry. Advantages include consistent product quality, straight forward automatic control and low manpower requirements.

The Armfield CEM MkII Continuous Stirred Tank Reactor is specially designed to allow detailed study of this important process. It is one of five reactor types which are interchangeable on the Reactor Service Unit (CEXC).

Reactions are monitored by conductivity probe as the conductivity of the solution changes with conversion of the reactants to product and by temperature.

Chilled Water Circulating Unit – CW-17 (Optional)

CET-MkII – Tubular Reactor

Tubular reactors are often used when continuous operation is required but without back-mixing of products and reactants.

The Armfield CET MkII Tubular Reactor is specially designed to allow detailed study of this important process. It is one of five reactor types which are interchangeable on the Reactor Service Unit (CEXC).

Reactions are monitored by conductivity probe as the conductivity of the solution changes with conversion of the reactants to product. This means that the inaccurate and inconvenient process of titration, which was formally used to monitor the reaction progress, is no longer necessary.

CEB-MkII – Transparent Batch Reactor

Batch reactors are used widely in industry at all scales. Batch reactors are tanks, commonly provided with agitation and a method of heat transfer (usually by coils or external jacket). This type of reactor is primarily employed for relatively slow reactions of several hours’ duration, since the downtime for filling and emptying large equipment can be significant. Agitation is used to maintain homogeneity and to improve heat transfer.

The Armfield CEB MkIII Transparent Batch Reactor is specially designed to allow detailed study of this important process. It is one of five reactors types which are interchangeable on the Computer Controlled Reactor Service Unit (CEXC).

Reactions are monitored by conductivity probe as the conductivity of the solution changes with conversion of the reactants to product and visually due to the use of indicators.

CEY – Plug Flow Reactor

The Armfield CEY-Plug Flow Reactor is an example of an ideal tubular reactor.

The CEY Plug Flow Reactor demonstrates step and pulse changes for plug flow characterisation and steady-state conversion for a second order reaction. It is a tubular packed column reactor made of clear acrylic and mounted on a steel frame. A static premixer at the bottom of the column provides premixing of the reagents entering the reactor and improves the flow distribution. It is one of five reactor types which are interchangeable on the Computer Controlled Reactor Service Unit (CEXC).

Reactions are monitored by conductivity probe as the conductivity of the solution changes with conversion of the reactants to product. In addition, all the experiments are followed visually by means of the reactor transparency and the use of colour indicators in all the experiments. Shown with CEXC

CEZ – Laminar Flow Reactor

The Armfield CEZ-Laminar Flow Reactor is an example of an ideal tubular reactor.

The CEZ Laminar Flow Reactor (shown with CEXC) demonstrates step and pulse changes for plug flow characterisation and steady-state conversion for a second order reaction. The Armfield Laminar Flow Reactor is a tubular reactor made of clear acrylic and mounted on a floor standing steel frame, with two diffusers packed with glass beads located at the ends. A static premixer at the bottom of the column provides premixing of the reagents entering the reactor and improves the flow distribution. It is one of five reactor types which are interchangeable on the Computer Controlled Reactor Service Unit (CEXC).

Reactions are monitored by conductivity probe as the conductivity of the solution changes with conversion of the reactants to product. In addition, all the experiments are followed visually by means of the reactor transparency and the use of colour indicators in all the experiments. Shown with CEXC

CEP-MkII – Stirred Tank Reactors in Series

The Armfield Stirred Tank Reactors in Series unit is designed to follow the dynamics of the perfectly mixed multi-stage process. Dynamic behaviour can be studied as can multi-stage chemical reaction.

Catalytic Reactors – 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.

Flow Injection Analysis – CEU-3 (Accessory)

Third Reactor Column – CEU-5

Fixed and Fluidised Bed Apparatus – CEL-MkII

The unit has three columns, one for use with water and two for use with air. The separate air and water columns enable the difference between ‘aggregative’ and ‘particulate’ fluidized bed characteristics to be demonstrated. The two air columns enable the effect of different packing material sizes to be demonstrated without having to remove, empty and repack a column.

Fluid Mixing Studies – CEK-MkII

Mixing of liquid / liquid or solid / liquid systems is a complex operation to analyse and subject to many variables. The choice of mixer for a particular application depends on the degree of bulk movement or shear mixing required by the process. This liquid mixing apparatus has been developed to demonstrate the factors affecting mixing using visualisation and measurement techniques as appropriate.

CEK-MKII – Fluid Mixing Studies

Solids Handling Study Bench – CEN-MkII

The flow and handling characteristics of granular materials are relevant to many process industries, particularly in the handling of powders, pellets, crystals and aggregates. The CEN-MKII introduces students to the behaviour of granular materials. The various teaching exercises are split between three units that can be purchased separately or as a complete set allowing only relevant equipment to be purchased. The following equipment is available: CEN-MKII-11 Solids Handling, CEN-MKII-12 Powder Handling, CEN-MKII-13 Vibratory shaker and sieves.

Corrosion Studies Kit – CEQ

The Armfield CEQ provides an introduction to corrosion, a significant factor in determining durability and safety of industrial processes. The CEQ allows students to recognise and make provisions for potentially corrosive situations. The equipment allows for the simultaneous study of up to eight corrosion cells. A pH meter and electrode are supplied to ensure the correct strength of initial test solutions. For the study of electro-chemical corrosion effects, a low voltage supply is included, together with all necessary electrical connections.

Mass Transfer and Diffusion Coefficients – CERa-MkII & CERb

Two separate items of laboratory equipment have been designed to enable measurement of molecular diffusitives, to familiarise students with the basic notions of mass transfer theory. The Gaseous Diffusivity Apparatus (CERa-MkII) involves diffusion with bulk flow, while the Liquid Diffusivity Apparatus (CERb) relates to equimolar counter-diffusion.

Wetted Wall Gas Absorption Column – CES

Wetted wall columns may be used to determine gas/liquid mass transfer coefficients, essential when calculating the design of absorption towers. Such coefficients form the basis of correlations used to develop packed towers.

CES examines the absorption of oxygen from air into deoxygenated water (prepared by nitrogen sparging). This is an example of liquid-film controlled absorption. The liquid-film mass transfer coefficient can be determined at various mass flow rates of water.
