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.
Process Design & Development
Bioreactor Design for Chemical Engineers
Gregory T. Benz
Fermentation processes are based on chemical engineering principles. Understand these concepts to achieve optimal bioreactor design.
Integrated Process Synthesis
As a chemical engineer, before you can make proposed process alterations you must consider the potential investment return. Yet, typically this involves detailed simulations and design work. Join process synthesis and integration experts Diane Hildebrandt and Bilal Patel and learn novel design and analysis techniques you can implement early on to avoid costly revisions to processes while reducing material and energy consumption and carbon dioxide emissions.
Select Heat-Transfer Fluids for Low-Temperature Applications
Satish C. Mohapatra
Consider such factors as thermophysical properties, toxicity, environmental concerns, and economics when choosing a fluid.
Optimize Pipeline Design for Non-Newtonian Fluids
Alejandro Anaya Durand, Cinthya Alejandra Anguilar Guerrero, Edgar Amaro Ronces
Use this graphical method to determine pipe diameter, fluid temperature and pressure drop for laminar and turbulent flow.
Shortcut Distillation Calculations via Spreadsheets
Jake Jevric, Muhammad E. Fayed
This method uses a numerical solution to the McCabe-Thiele diagram to find the theoretical number of stages for binary and pseudo-binary systems,then calculates the actual number of stages, reflux ratio and column dimensions.
Properly Employ Overhead Condensers for Vacuum Columns
David Greene, George G. Vago
Follow these guidelines for specifying, selecting and designing overhead vacuum condensers.
Prevent Caking During Solids Handling
Brian H. Pittenger, Gabriel I. Tardos , Herman Purutyan
Use these guidelines to avoid potential caking problems. The key steps are to select a material characterization method, identify the factors that can be feasibly controlled and conduct tests to confirm that process/handling changes yield the...
Increase Powder Flow via Gas Injection
Herman Purutyan, John W. Carson, Thomas G. Troxel
Fluidization and air-assisted discharge are two ways to optimize fine-solids handling. However, the choice of technology is as important as designing and operating the system properly.
Create Business Value Through Process Modeling
Bernard McGarvey
As businesses strive to improve productivity, process modeling can be a powerful tool. This article explores the role of modeling in enhancing the effectiveness and efficiency of process development and manufacturing.
Understanding Electromagnetic Flowmeters
Ronald W. DiGiacomo
Consisting of a flow tube, field-generating coils, electrodes, and a transmitter, a magmeter accurately measures the flowrate of conductive fluids over a wide range of conditions.
Designing Dust Collectors
Greg Mehos, P.E.
To assure reliable and safe operation of a dust collector, apply the basic principles of chute and hopper design — which are based on the dust's fundamental flow properties.
