Provides background information, apparatus needed, and procedures for an experiment to measure transient response of a stirred vessel. The inexpensive apparatus can be used for two different experiments, reducing cost per experiment. Both experiments use salt dilution as the method of demonstration. (Author/JN)

Ethylene hydrogenation on a platinum catalyst, electrolytically applied to a tube wall, is a good system for the study of the interactions between diffusion and surface reaction in heterogeneous catalysis. Theoretical background, apparatus, procedure, and student performance of this experiment are discussed. (BB)

An engineering hardware display, slide-tape show, selected readings, and tests are used to help students become familiar with values, fitting, tools, and instruments. Sample exam questions and a list of hardware are given. (BB)

Discusses a simple method for following the movement of a solute in an adsorption or ion exchange system. This movement is used to study a variety of operational methods, including continuous flow and pulsed flow counter-current operations and simulated counter-current systems. Effect of changing thermodynamic variables is also considered. (JM)

This paper describes an experiment designed to reveal the consequences of the development of a concentration boundary layer. The rate of a mass transfer limited electrochemical reaction is measured and used to obtain the dependence of average Sherwood number on Reynolds number and entrance length. (Author/BB)

Describes a reaction system experiment utilizing saponification of ethyl acetate by sodium hydroxide. The activity is part of an undergraduate chemical engineering course. (SL)

Considers the deviation from the ideal flows of both a backmix tank and a backmix tank followed by a flow vessel. Background information, apparatus used, and experimental procedures are provided. Typical results are also provided and discussed. (JN)

Principles, experimental procedures, results, and discussion of this method are included here. The method was used in undergraduate laboratory courses in Toulouse, France. (BB)

Previously described a class experiment which employs the hydraulic analog to represent systems of first order reactions in batch reactors. The hydraulic experiments are extended to represent reaction systems with nonlinear systems. (JN)

As part of a project focusing on techniques in industrial chemistry, students carry out experiments on separating copper from cobalt in chloride-containing aqueous solution by liquid extraction with triisoctylamine solvent and search the literature on the separation process of these metals. These experiments and the literature research are…

Describes an experiment in which a microcomputer was programed to function as a transfer function analyzer to investigate the dynamics of stirred vessels. The main objective of the experiment is to illustrate the theory and application of the pulse test (a method of determining the transfer function of a process). (JN)

For this 12-hour laboratory project students examine a model and explain why equipment is placed where it is, and then install some piping on the model. (BB)

Introduces a procedure for a whole class of experiments which require very simple and inexpensive equipment and which illustrate one of the basic problems of chemical reaction engineering. The reactions are designed to allow development of a kinetic rate equation from laboratory data. (JM)

Described is a laboratory experiment designed to expose students to problem-solving methods individually and as a group. Included are background information, a list of materials, laboratory procedures, analysis methods, and probable results. (CW)

Described is a project where students gain experience in handling large volumes of hazardous materials, process start up and shut down, equipment failures, operational variations, scaling up, equipment cleaning, and run-time scheduling while working in a modern pilot plant. Included are the system design, experimental procedures, and results. (KR)
