The gaining of skill in solving practical engineering problems is very important for students of the course in unit operations. The Department of Unit Operations of Chemical Engineering at the Leningrad Technological Institute places great emphasis on this aspect, and the present book contains many examples and problems in the course that are the result of many years of instructional experience.

Great attention is devoted to the independent work of students, and problems are provided on all sections of the course:

Fundamentals of applied hydraulics
Pumps, fans, compressors
Hydromechanical separation methods
Hydrodynamics of a fluidised bed
Agitation in a liquid medium
Heat transfer in chemical apparatus
Evaporation, crystallisation
Mass transfer, absorption
Distillation and rectification
Extraction and leaching
Adsorption
Drying
Moderate and deep refrigeration
The basic formulas and equations needed for solving the problems are given at the beginning of each chapter. The appendices contain numerous reference tables and diagrams.

The present book, edited by Associate Member of the USSR Academy of Sciences, P. G. Romankov, is intended as a training aid for students of chemical engineering and related specialities in day, evening, and correspondence faculties. It will also be a useful aid in course and diploma designing.

About the Authors

Konstantin F. Pavlov (1895–1944)
Konstantin F. Pavlov was an outstanding specialist in the separation of natural and industrial gases. In 1934, he received his doctorate and the rank of professor. He headed the departments of Chemical Engineering of Inorganic Substances and General Chemical Engineering at the Leningrad Technological Institute, where, in 1936, he founded the first training laboratory in unit operations of chemical engineering in the country (now named after him).

He is the author of several training aids in chemical engineering and original research works (e.g., the rule of linearity of chemical engineering functions). During his final years, he worked in Moscow at the Institute of Physical Problems of the USSR Academy of Sciences.

Pyotr G. Romankov, D.Sc.
Professor Pyotr G. Romankov worked for many years as a chemical engineer and instructor at various chemical institutes. Since 1941, he has been the head of the Department of Unit Operations of Chemical Engineering at the Leningrad Technological Institute. Together with his pupils and collaborators, he has published over 250 scientific works, including several monographs on the theory and application of hydromechanical, heat, and mass-exchange processes of chemical engineering.

In 1964, Pyotr Romankov was elected an associate member of the USSR Academy of Sciences. He is an Honoured Scientist of the RSFSR and has received numerous government awards. He is also a Doctor honoris causa of several foreign higher educational establishments.

Anatoli A. Noskov (1904–1977)
Anatoli A. Noskov worked for many years as an engineer in gas separation under the guidance of Prof. Konstantin Pavlov. He was later invited to work at the Department of Unit Operations of Chemical Engineering at the Leningrad Technological Institute, where he advanced from lecturer to professor.

Anatoli Noskov is well known for his contributions to improving rectification processes and methods for calculating standard operations of chemical engineering.
