Selecting a Membrane Filtration System
Frank Parma , Wu Chen
Proper design and scaleup of a membrane filtration system requires an understanding of the availability of membrane material, pore size and module configurations. These practical guidelines will help in the selection process.
Pervaporation Comes of Age
Nick Wynn
This membrane process has found growing use for dehydrating organics. Uses keep increasing, mostly due to development of new, high-temperature membranes.
Understanding RO Membrane Performance
Jane Kucera
Follow these guidelines to prevent fouling, scaling and degradation of reverse osmosis membranes.
Streamlining Crystallization Process Design
Christianto Wibowo, Ka M. Ng, Lionel O'Young
Use phase diagrams to develop reliable crystallization processes quickly and cost effectively.
Ionic Liquids for Aromatic Extraction: Are They Ready?
Sachin T. Anjan
Ionic liquids have already moved into the commercial arena as reaction solvents. This article compares them to conventional solvents and examines their potential for the extraction of benzene, toluene and xylene from reformate.
Can We Believe the Simulation Results?
Henry Z. Kister
Be careful of these key issues that may generate differences between a distillation-tower simulation and its actual performance. Simulations do not always square with nuts-and-bolts reality.
Designing Four-Pass Trays
Daniel R. Summers
Use this procedure to design four-pass distillation column trays and to balance the vapor/liquid ratio on each tray panel.
Catalyst Recovery Part 1: Recovering Precious Metals from Catalysts
Robert T Jacobsen
When selecting a precious metals refiner, it’s important to first understand the basics of sampling, assaying and environmental issues, as well as the concept of leasing metal.
Size Letdown Lines for Pressure Surges
Gianni Anci
A high-pressure gas flow in a letdown circuit can cause damage to piping and equipment. Here is how to design a system to avoid damage should a pressurized gas flow occur GianniAnci-
Effects of Design on Tray Efficiency in Commercial Towers
Henry Z. Kister
When designing a new distillation column or revamping an existing one, it is important to understand the factors that affect overall tray efficiency.
Properly Employ Overhead Condensers for Vacuum Columns
David Greene, George G. Vago
Follow these guidelines for specifying, selecting and designing overhead vacuum condensers.
Addendum to Realistically Predict Capacity and Pressure Drop for Packed Columns -- Original Paper as presented at the 2007 Spring National Meeting
GPDC Interpolation: Use, Misuse and Updates
Dividing-Wall Columns Find Greater Appeal
Gerald Parkinson
Conceived more than seven decades ago, dividing-wall columns are now only gaining widespread acceptance. The reasons— the drive to save energy and advances in computer technology that have overcome the burden of doing complex column internal designs.
Teach Yourself the Basics of Aspen Plus
January, 2011
Aspen Plus is on of the most popular process simulation software programs used industrially and academically. Though the software is available at many corporations and universities, there are no textbooks which are dedicated to teaching the step-by-step use of the software. This book is designed to...
Reactive Distillation Design and Control
October, 2008
After an overview of the fundamentals, limitations, and scope of reactive distillation, this book uses rigorous models for steady-state design and dynamic analysis of different types of reactive distillation columns and quantitatively compares the economics of reactive distillation columns with...
