Multistage Separation Processes

The development of computer-aided simulation programs for separation processes provides engineers with valuable tools to make more reliable qualitative and quantitative decisions in plant design and operation. Written by a specialist in modeling and optimization, Multistage Separation Processes, Third Edition clarifies the effective use of simulators by giving a conceptual analysis of the material and explaining various computation techniques.

The book accentuates performance prediction, an essential component of the efficient design and operation, of multistage separation processes. Unlike other textbooks, this book emphasizes computer modeling, expert interpretation of models, and it discusses modern simulation techniques. It presents rigorous mathematical models of separation processes, illustrated by numerous examples from a variety of applications, and demonstrates their performance under varying conditions and different operating variables. The author also shows how shortcut and graphical methods can be used to make preliminary and reliable decisions on action plans. He explains the major algorithms used for solving multi-component separations and features techniques used to combat factors that affect control and optimization of separation processes.

This third edition presents a significant amount of new information, including new material on column dynamics, batch distillation, membrane separations, dialysis, reverse osmosis, dynamic behavior, and multivariable control issues. Organized in self-contained chapters that follow a logical flow of ideas, the new edition of Multistage Separation Processes is an ideal textbook for advanced university students and a valuable reference for practicing engineers in the process industry and in engineering process design, particularly in the petroleum, petrochemical, and chemical industries.

Separation, Preconcentration and Spectrophotometry in Inorganic Analysis

Spectrophotometry enables one to determine, with good precision and sensitivity, almost all the elements present in small and trace quantities of any material. The method is particularly useful in the determination of non-metals and allows the determination elements in a large range of concentrations (from single % to low ppm levels) in various materials.

In Separation, Preconcentration and Spectrophotometry in Inorganic Analysis, much attention has been paid to separation and preconcentration methods, since they play an essential role in increasing the selectivity and sensitivity of spectrophotometric methods. Separation and preconcentration methods have also been utilised in other determination techniques.

Spectrophotometric methods which are widely used for the determination of the elements in a large variety of inorganic materials are presented in the book whilst separation and preconcentration procedures combined with spectrophotometry are also described.

This book contains recent advances in spectrophotometry, detailed discussion of the instrumentation, and the techniques and reagents used for spectrophotometric determination of elements in a wide range of materials as well as a detailed discussion of separation and preconcentration procedures that precede the spectrophotometric detection.

A Marine Affair (Always a Marine series Book 13)

Secret lovers for years, Commander Rick McConnell and Colonel Elijah Masters have nurtured their very private relationship with planned vacations and leaves, always meeting somewhere different—always escaping off the grid. It worked for them—career officers with a desire to serve their country and a passion for each other.

The repeal of the military’s policy, Don’t Ask, Don’t Tell, provides them with the tremendous opportunity to come out to their friends and loved ones. Rick wants to seize the day, but Eli isn’t so certain. His hesitation leads to a fight, an ultimatum, and a breakup. Rather than confront their issues, Eli takes a foreign assignment.
