Background information, procedures used, and typical results obtained are provided for an experiment which: (1) examines the effect of residence time on conversion in a tubular flow reactor; and (2) compares the experimental conversions with those obtained from plug-flow and laminar-flow reactor models. (JN)

Describes a semester-long project in which students designed, built, and operated an apparatus to separate particles by fluidization principles. Each laboratory group worked on a separate step of the design in a sequence selected by the instructor in a manner similar to the way a design team might function. (JN)

Describes a drying experiment useful in presenting the concept of simultaneous heat and mass transfer. Background information, equipment requirements, experimental procedures, and results are provided. The reasonably good agreement in the calculated rate of drying and that observed experimentally makes students feel confident in applying…

Discusses features of experiments (conducted during 1980-81 in the University of Edinburgh's third-year chemical engineering laboratory) which might make them attractive for wider use. Experiments focus on convective mass and heat transfer, diffusion, heat transfer to a jet, and adiabatic batch reactors. (JN)

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)

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)

Described is an experiment which uses an autotrophic bacterium to anaerobically oxidize hydrogen sulfide to sulfate in a batch-stirred tank reactor. Discusses background information, experimental procedure, and sample results of this activity. (CW)

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)

Discusses the use of an individually designed experiment for a chemical engineering laboratory course. Lists main ideas of the method. Provides an example of the experiment including ways to answer the questions and extensions. (YP)

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)

This article focuses on the changes made in the undergraduate laboratory program of the first degree course in chemical engineering at the University of Bath (England). Describes experiments relating to the Engineering Applications 1 (EA1) requirements set by the Engineering Council. (YP)

Describes a course entitled "Biotechnology Laboratory" which introduces a variety of laboratory methods associated with biotechnology. Describes the history, content, and seven experiments of the course. The seven experiments are selected from microbiology and molecular biology, kinetics and fermentation, and downstream…
