This in-depth revision provides a summary of current knowledge, updated based on the most recent literature in the field. The reader will find recommendations on the choice of correlations to apply, depending on the case, and useful references to the original documents on industrial processes. This practical user's guide is designed for engineers in industries involved with the problems of chemical transformations, and for professors and students of process engineering. Whether the reader is working in a design department, an engineering firm or an R&D department, or is managing production plants, he will find material here that is directly applicable to the solution of his problems.Contents: 1.
