Choose the Right Elastomer
William M. Stahl
Match a material's performance to process conditions to reduce leaks, improve safety and extend the mean time between failures (MTBF).
Chemical Engineering Practice
Improve Flange Joint Reliability
John Ludman, Mike Emery, Thomas Sandbrook
Proper design, installation, and maintenance of flanged connection systems can prevent loss of containment and process interruptions. Follow this seven-step approach to ensure reliability of this critical process equipment.
Inhibiting and Monitoring Corrosion
Gary Geiger, Mel J. Esmacher, P.E.
Understand corrosion and ways to control it, and implement these monitoring techniques to improve cooling water system efficiency and reliability and reduce energy consumption.
Take Another Look at Steam Traps
S. Raghavi Chari
Think twice before installing a steam trap. In the case of superheated lines, steam traps may prove to be a waste of time, effort, and money
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.
Evaluating Dryers for New Services
Charles G. Moyers
Continuous dryers are accurately and easily evaluated using laboratory-scale simulators combined with the specific drying rate approach.
Effectively Manage the Lifecycle of a Product
Baha Korkmaz, Marty Martin
By incorporating the batch standards S88 and S95 into the entire product lifecycle, companies can optimize their processes and project management. This enables them to rapidly get their products to market — a critical factor in staying competitive.
Minimize Scale-Up Risk
Bertil Stromberg, J. Brad Cort, Thomas Pschorn
Proven commercial-scale equipment already exists for many operations involved in producing biofuels from lignocellulosic feedstocks.
Reduce Piloting Time and Cost
David A. Berg, Michael T. Cleary
Pilot-scale experimentation is essential to establish a sound foundation for a new chemical processing unit. These best practices can reduce the time and cost involved in process development.
Use the Correct Constant-Volume Specific Heat
John Garvin
The common assumption that for real liquids cv can be approximated by cp is not correct. To get accurate cv values, use equations of state.
Increase Capacity and Decrease Energy for Existing Refinery Distillation Columns
Mamdouh Gadalla, Megan Jobson, Robin Smith
This method optimizes the existing distillation system and its heat-exchanger network simultaneously, lowering energy consumption and freeing up capacity at a minimum capital investment.
Implementing an EHS Management Information System
Jill Barson Gilbert
Information technology issues are just as important as business and environmental, health and safety considerations. Follow these ten tips to deply an effective EMIS with a positive return on investment.
Eliminate Iteration from Flow Problems
John D. Barry
This article introduces a novel approach to solving flow and pipe-sizing problems based on two new dimensionless quantities that are independent of line size and flow.
Predicting Emissivities of Combustion Gases
Alireza Bahadori, Hari B. Vuthaluru
Use this new correlation, which employs easy-to-solve algebraic equations to estimate gas emissivities, to simplify the design and optimization of boilers, furnaces and other combustion equipment.
Learn to Effectively Operate and Maintain Pumps
Daniel Kernan
Centrifugal pumps play a central role in chemical processing. Proper pump operation and maintenance can improve a facility's productivity, reduce downtime, and trim costs.
Uncovering the Realities of Simulation
Andrew Vieler, Marco S. Satyr, Oscar Santollani , Rajeev Agarwal, Yau-Kun Li
Running sophisticated process simulations does not guarantee correct results. You need to understand the thermodynamic assumptions underlying the program and how to ensure proper applications.
