Engineering to Business: Optimizing Asset Utilization Through Process Engineering
Andy Howell, Kevin Hanson, Vikas Dhole, Wayne Sim
Asset owners who integrate the process engineering, operations and business lifecycles of their facilities can improve return-on-capital by up to 4%. Use this virtual-asset model (VAM) to optimize your business assets.
Real World Modeling of Distillation
Harry Kooijman, Rajamani Krishna , Ross Taylor
Previously, simulations based on nonequilibrium, or rate-based, models were considered impractical due to their complexity. However, with ever-increasing computing power, these simulations are not only feasible, but in some circumstances they should...
Clarifying Centrifuge Operation and Selection
Victor Norton , William Wilkie
Before selecting a centrifuge for your application, understand its principles of operation and investigate the key process variables.
Integrate Process Simulation and Process Synthesis
Dominic Chwan Yee Foo, Michael Lynn McGuire, Murugan Selvan, Zainuddin Abdul Manan
The design of a new process using computer simulations to analyze a process flowsheet based on the onion model can save time, effort and, ultimately, money.
Improve Control of Liquid Level Loops
Douglas J. Cooper, Robert Rice
Use this tuning recipe for the classic integrating process control challenge.
Uncovering the Realities of Simulation, Part 2
Andrew Vieler, Marco S. Satyro, Rajeev Agarwal, Yau-Kun Li, Oscar Santollani
Simulation software is a commonly used design tool, thanks mainly to its availability on the desktop. However, one has to understand thermodynamic basics before accepting the desktop's final answer.
Prevent Fires in Thermal Fluid Systems
Jim Oetinger
Follow these design and operating guideines for a safe heat-transfer-fluid system.
Troubleshooting Bins, Hoppers and Feeders
Jerry R. Johanson
By understanding solids' properties and what promotes flow, problems faced in the plant can be remedied
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.
Streamlining Crystallization Process Design
Christianto Wibowo, Ka M. Ng, Lionel O'Young
Use phase diagrams to develop reliable crystallization processes quickly and cost effectively.
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.
Designing a Facility for API Development
Terrence Fay, Yasha Zelmanovich
Kilo labs are instrumental in scaling up the production of active pharmaceutical ingredients. This article discusses the critical factors that must be considered to design such a facility.
Selecting Laboratory Reactors
Francesco Picciotti, Marcello Picciotti
This article outlines some of the considerations involved in selecting and specifying a reactor system for research and development applications.
Developing Screening Cost Estimates
Richard P. Palluzi, P.E.
Making decisions based on estimates derived from weak data is counterproductive. Use this established methodology to prepare scoping and screening cost estimates for pilot plants quickly and accurately.
Effectively Control Column Pressure
Andrew W. Sloley
Maintaining proper pressure can play a crucial role in the stable operation of a distillation column. Here’s how to select the most appropriate pressure-control scheme.
