Mechanical unit operations

This brief summary of the state of current instrumentation for the total automation of pesticide analyses will hopefully entice the reader to apply these principles of mechanized unit operations to his own analytical problems. There are enough creative scientists in this field, each trying to lighten his workload, that it seems safe to make this prediction by 1984 we ll have a pesticide analyzer which will take our unmeasured, untreated sample into one end of the instrument and give us final answers, printed in correct concentration units, twice as fast as today, with one tenth the sample size, and with half the CV s. If an analyst makes up his mind to do so, he can likely automate anything. [Pg.29]

The book is divided into three parts. Part I surveys concepts for heat-integrated chemical reactors, with special focus on coupling reactions and heat transfer in fixed beds and in fuel cells. Part II is dedicated to the conceptual design, control and analysis of chemical processes with integrated separation steps, whilst Part III focuses on how mechanical unit operations can be integrated into chemical reactors. [Pg.557]

The particle size range of mechanical processes and of all mechanical unit operations (see Chapter 1, Fig. 1.1) now extends down to nano meters. Although, in comparison with the atomic scale, ultra-fine particles <0.1 pm or <100 nm are still large... [Pg.101]

The active components are dissolved and then precipitated under certain conditions (T, pH, stirring speed, etc.). The resulting precipitate is dried and subjected to a series of mechanical unit operations (filtration, drying, shaping, calcination, etc. Figure 2.1-6). The catalyst mass thus obtained can be shaped in pure form by pressing or extrusion or applied as a thin layer on steatites (magnesium silicate) spheres (shell catalysts). [Pg.25]

This book covers all four disciplines chemical aspects in Chapter 2, thermal and mechanical unit operations (Chapter 3), reaction engineering (Chapter 4), and general chemical technology (Chapter 5). In addition, 20 industrial processes are inspected in detail (Chapter 6). [Pg.2]

In Chapter 3, the following thermal and mechanical unit operations will be... [Pg.39]
