The book "Technological calculation of the extraction column" by the authorship of the team of authors under the guidance of T. In. Prokofiev is an indispensable manual for students, graduate students, engineers and anyone interested in technological processes in the chemical and food industry. This work provides in-depth research and practical guidance on the calculation of extraction columns, which play a key role in the process of separation and purification of substances. Extraction is an important process used to extract valuable components from raw materials, and the correct calculation of the column is the key to the efficiency and economy of the entire production cycle. The book discusses in detail the theoretical foundations of extraction, methods of calculation and design of columns, as well as the practical aspects of their operation. The reader will find here not only theoretical calculations, but also examples of calculations, which makes the material accessible and understandable. The book will be of particular interest to engineering students studying chemical technology, as well as practicing engineers who want to deepen their knowledge in the design and optimization of technological processes. If you are looking for information on how to properly design an extraction column, how to choose the optimal parameters to achieve maximum efficiency, then this publication will become your reliable assistant. The topics raised in the book cover a wide range of issues, such as the choice of solvents, the effect of temperature and pressure on the extraction process, as well as methods for optimizing the work of columns. The authors focus on current trends in the field of extraction, including the use of new technologies and materials, which makes the book relevant and useful for professionals working in this field. The style of the authors is distinguished by the clarity and accessibility of the presentation, which makes it easy to assimilate even the most complex concepts. The book is written taking into account the latest achievements of science and technology, which makes it not only a textbook, but also a guide for practitioners. The team of authors, including experts in the field of chemical technology, shares their experience and knowledge, which adds value to each section. If you are interested in such topics as “extraction technology”, “column design”, “chemical technology” or “optimization of production processes”, then this publication will be a real find for you.
