Distillation, part of the Industrial Equipment for Chemical Engineering set, includes thirteen independent volumes that define how to perform the selection and calculation of equipment involved in the thirteen basic operations of process engineering, also offering reliable and simple methods.Throughout these concise and easy-to-use books, the author uses his vast practical experience and precision knowledge of global research to present an in-depth study of a variety of aspects within the field of chemical engineering, with this volume focusing on the process of distillation.Using both practical and theoretical examples, the author describes the various reactions and steps involved in separating out the components of a mixture to attain predefined levels of purity. By investigating different types of liquids, an array of column sizes, and the plates involved in distillation, readers will gain a wide understanding of the physics of liquids.The book also details the methods needed to understand the machinery used in applied thermodynamics in the hopes of encouraging students and engineers to manually build the programs they need. Chapters are complemented with appendices that provide additional information and associated references.- Contains a practical and theoretical focus on the process of distillation- Provides a clear analysis on the topic that includes practice applications in process engineering- Uses both practical and theoretical examples to describe the various reactions and steps involved in separating out the components of a mixture to attain predefined levels of purity

Theoretical Plates in Distillation, Absorption and Stripping – Choice of Type of Column

Abstract

A theoretical plate is characterized by the fact that the vapor and the liquid it leaves behind are at equilibrium in terms of pressure, temperature and composition. Each theoretical plate is a point on the equilibrium curve y_i = f(x_i). The vapor leaving the plate is always richer in lightweight substances than the liquid left behind. Thus, at the top of the column, light weights are found in the distillate, and at the bottom, heavier materials are recovered in the residue.
