EXAMPLES AND PROBLEMS
TO THE COURSE OF UNIT OPERATIONS
OF CHEMICAL ENINEERING

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.
