Synopsis

A column floods at a feed rate it should handle. A pump will not deliver the flow the operator expects. A reactor temperature drifts upward faster than anyone predicted. In every case the answer lies in a small set of principles applied with care, and in the ability to move calmly between the plant-floor question and the mathematics that answers it.

That ability is harder to build than it should be. Many references present theory without the full calculation or tables without the reasoning behind them, and the most common errors in process calculations are errors of units, basis, and unstated assumptions rather than errors of algebra. Simulation software returns confident numbers whether or not the inputs were sound, and an engineer who cannot estimate the magnitude by hand has no way to judge the result.

This handbook was written to make the principles of chemical engineering usable. It is organized as a working reference and a teaching text at once: fifteen self-contained chapters, each opening with learning objectives, developing the theory from fundamentals, solving worked examples step by step with units carried through every line and every assumption stated, and closing with practice problems and answers so the method can be tested immediately.

Inside, you will learn to:

  • Set up material and energy balances on single units, multiple-unit flowsheets, and systems with recycle, bypass, purge, and reaction, using degrees-of-freedom analysis to confirm a problem is solvable before you begin.
  • Apply vapor-liquid equilibrium, flash calculations, and activity-coefficient methods to real mixtures, and recognize the common errors that make equilibrium calculations go wrong.
  • Size pipes, pumps, and heat exchangers, calculate friction loss and net positive suction head, and diagnose cavitation and loss of exchanger performance from plant data.
  • Derive rate laws from batch data, size batch, stirred-tank, and plug-flow reactors, and account for non-ideal flow, catalyst pellets, and heat effects in real reactors.
  • Design distillation, absorption, extraction, and adsorption units from equilibrium data through operating lines, stage counts, transfer units, and column diameter and height.
  • Tune feedback controllers, read piping and instrumentation diagrams, carry out hazard studies and layer-of-protection analysis, and estimate capital cost, operating cost, and profitability.

Nearly one hundred and fifty worked examples carry the teaching. Integrated case studies take a binary distillation from specification to equipment, analyze a reactor with recycle and purge, diagnose a heat exchanger losing performance, design an absorber removing a pollutant from a gas, and troubleshoot a pump and piping system. A systematic troubleshooting method, a glossary, five appendices of constants, conversion factors, and typical design values, and a complete index make the book a fast reference long after it has been read.

The handbook is written for upper-level undergraduate and graduate students, practicing chemical and process engineers who want a rigorous refresher or a dependable companion at the desk, and engineers from adjacent disciplines who work alongside them. SI units are used throughout, with US customary units shown where industrial practice still relies on them.

Open the handbook at the chapter you need today, follow the calculation line by line, and start building the habit of checking every number against physical sense before you accept it.
