The main objective of laboratory courses in chemical engineering is to familiarize
undergraduate students with the theory that they learn during their course and to verify the consistency of experimental results with those of the theory. Laboratory practice plays an important role in chemical engineering curricula. Due to this there is a need to expose undergraduates (UGs) to experiments that explain important concepts. Although a large number of experiments are available in chemical engineering literature, they are scattered and there is a need to collect them in one book; hence I have undertaken the task of writing a book on a laboratory course in chemical engineering. Generally about three hours is allotted for an experiment in the laboratory, hence the aim of the present book is to give experiments that can be performed within three hours.
An important aspect in laboratory courses in chemical engineering is the cost of the experiments. The cost of an experiment consists of two components, namely the fixed cost and the running cost. In all experiments, discussed in this book care has been taken to minimize these costs. The development of cost effective laboratory teaching tools is an imperative task in all institutions of higher education, particularly in the light of recent cost cutting initiatives. Therefore, throughout the book emphasis is laid on low-cost experiments. In addition to cost minimization, an attempt has been made to give the maximum information on the experiments chosen along with the possible systems that can be used for the laboratory experimentation. In this book I have selected various experiments from core chemical engineering subjects such as unit operation, reaction engineering and process control. Unit operations include momentum transfer operations, heat transfer operations, mass transfer operations and mechanical operations. The book has been prepared essentially for students and junior faculty members of various newly established colleges, where there may be a need for experimental details for instruction.
All experiments are broadly discussed under eight subtitles. Overall details are as follows. First subtitle introduces the aim of the experiment, the second subtitle gives an introduction to the experiment, the third subtitle discusses the theory related to that particular experiment, the fourth subtitle describes the experimental set-up, the fifth subtitle explains the experimental procedure, the sixth subtitle presents the calculations required in the experiment along with possible systems, the seventh subtitle represents the results and the eighth subtitle gives references related to the experiments.
The experimental apparatus discussed in this book is made out of materials such as glass and stainless steel (SS). These experiments use simple auxiliary devices such as thermometers, digital balances, measuring devices such as measuring cylinders,separating funnels, digital watches, tap connecters, plastic tubes, conductivity meters etc.
Further viva voice questions along with the answers are also included in the last section.
The book is intended for students, professionals and academicians in the ChemicalEngineering, Mechanical Engineering, Biochemical Engineering, Biotechnology, Food Engineering, Petrochemical Engineering, Polymeric and Pharmaceutical Engineering streams.
