How do you know whether your separation design is physically sound-or whether one hidden assumption about equilibrium, mass transfer, hydraulics, or energy will make it fail when the calculation meets real equipment?
You may have collected formulas for individual unit operations, yet still struggle to decide which model applies, whether the specification is feasible, or how an ideal-stage result becomes a preliminary equipment design. That uncertainty costs time, weakens your calculations, and makes it harder to defend decisions about purity, recovery, utilities, capacity, and cost.
Separation Process Principles Handbook gives you a unified method for analysing and developing separation systems from first principles. It begins with thermodynamics, balances, diffusion, and interphase transfer, then applies those foundations to major unit operations before connecting them through energy integration, control, safety, and economic evaluation. Worked examples show the assumptions, units, calculation sequence, and reasonableness checks behind each result.
With this handbook, you will be able to:
Select an appropriate separation method by matching feed properties, product targets, driving forces, and operating constraints.
Calculate flash conditions, phase fractions, equilibrium compositions, and feasible purity or recovery limits.
Determine stages, reflux, solvent rates, transfer units, membrane area, bed depth, filtration area, and other preliminary design requirements.
Evaluate mass-transfer resistance, stage efficiency, pressure drop, flooding, entrainment, fouling, breakthrough, and capacity limits.
Compare distillation, absorption, extraction, adsorption, membranes, evaporation, crystallization, drying, and mechanical alternatives.
Estimate utility demand, examine heat recovery, and compare capital and operating consequences.
Test a proposed design for controllability, safety, maintainability, environmental performance, and physical reasonableness.
Topics include vapour-liquid and liquid-liquid equilibrium, diffusion coefficients, film theory, stagewise and rate-based contacting, binary and multicomponent distillation, gas absorption and stripping, leaching, ion exchange, chromatography, membrane transport, humidification, solid-fluid separations, hybrid flowsheets, and numerical solution methods. Reference appendices provide unit conversions, property correlations, calculation workflows, and preliminary equipment-selection tables.
This handbook is written for upper-level chemical engineering students, graduate students, practising chemical and process engineers, and technical professionals who need a rigorous study aid or desk reference. It is especially useful when you must move beyond memorised equations and explain why a model, assumption, or equipment choice is appropriate.
If you want a disciplined path from separation objective to technically defensible preliminary design, add this handbook to your working library. Use it to calculate more carefully, compare alternatives more intelligently, and recognise the limits of your model before those limits become expensive problems.
