Each chapter starts with an introduction Various operations and their fundamental principles are explained Text is complemented by 153 worked examples 169 exercise problems are provided with solutions Mass transfer involves the use of various operations to separate a mixture into its individual components—a frequent requirement in chemical industries. The differences in the physical properties of the components to be separated – such as the vapour pressure, solubility or diffusivity – are utilised to transfer material from one homogenous phase to another. Techniques such as gas absorption, distillation, leaching, extraction, crystallisation, humidification, drying, adsorption and membrane based separation processes involve mass transfer and can be carried out due to the existence of a concentration gradient within the system. Mass Transfer Concepts equips an engineer with knowledge of all these operations.
Dr K Asokan is Deputy Director and Head, Chlor-Alkali Division, Central Electro Chemical Research Institute (CECRI), Karaikudi. He has been teaching mass transfer, heat transfer and chemical process calculations since 1988. He is involved in the development and commercial exploitation of titanium substrate insoluble anodes – a substitute for the conventional graphite anodes – which revolutionised the Indian chlor-alkali industry during the 1980s. Dr Asokan has published several research papers in national and international journals of repute in the area of electrolytic production of organic and inorganic chemicals based on membrane cell technology. He has four Indian patents and one US patent to his credit. He has earlier authored a book, Chemical Process Calculations (Universities Press, 2007)
