Using High-Fidelity Dynamic Simulation to Model Compressor Systems
Abhilash Nair, Ian Willetts
Enjoy the benefits of “20-20 hindsight” even before commissioning a new compressor or new compressor controls.
Process Control
Reduce Thermal Risk in Industrial Synthesis
Richard C. Wedlich
Knowing the safe operating conditions for a reaction allows us to select appropriate safety measures and thereby lower both the likelihood and the severity of a thermal runaway.
Using Automation to Produce Quality Pharmaceuticals
Joseph S. Alford, P.E.
Automation can pay large dividends in the form of reduced process cycle times, lower operational costs, and more-consistent processes for manufacturing high-quality pharmaceutical products.
Dynamic Simulation - Modeling Processes, the Environment, the World
Irving J. Dunn, Ronald A. Shelden
Simulation methods offer a way to study the influence of control algorithms and their parameters
The Chemical Industry Phoenix
Terry McMahon
Seven years ago, I wrote a column for another publica tion entitled “The U.S. Chemical Industry: R.I.P.” This pillar of American economic strength, which a few years earlier was the leading exporter among U.S. manufacturing sectors (with net exports of $15–20 billion annually), was shriveling due in large part to policy blunders and regulatory mistakes.
Optimize Process Regulation
Phillip D. Schnelle
Laboratory feedback proportional-integral control integrates statistical process control with automatic process control to minimize process variability.
Implement an Effective Loop Tuning Strategy
Norman Ito, Timothy Olsen
Use these loop tuning guidelines to improve process control and enhance product uniformity Many undergraduate chemical engineering programs teach the Ziegler-Nichols tuning methods, developed by John G. Ziegler and Nathaniel B. Nichols in the 1940s...
Tune Control Loops for Minimum Variability
Lanny A. Robbins
The Robbins tuning rules can reduce the variability of control loop response to about 60% of that observed with Ziegler-Nichols tuning rules.
Step into the Virtual Plant
Gregory K McMillan, Mark S Sowell III, Michael M Mansy
The ability to warehouse process and control system knowledge offers a vast potential for improved operations by sharing a common source of information and avoiding data duplication.
Tracing Process Problems
John E. Hoots
In water chemistry control, fluorescent tracing technology can quickly and effectively determine and deal with the root cause of a problem.
Fuels Blending Technology and Management
In today’s highly competitive marketplace, the economic and efficient management of blending operations and automation can give you that critical edge over competitors. Join refinery offsite automation expert Suresh S. Agrawal for an overview of the principles of operation and decision-making involved in the management, operation, control, optimization and scheduling of gasoline, diesel, fuel oil products and crude oil.
Analyzing APC Performance
To reap the most benefit from an advanced process control (APC) system, users need to know how to analyze and monitor the APC's performance.
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.
Ease Control Valve Selection
Kiran Nair, Liyakat Jaffer, Meredith Chapeaux, Sheetal Patel, Trevor Bishop
With so many types and options available, choosing the right control valve can seem daunting. Selection can be simplified by considering the process fluid, the service requirements, how the various valves function, and seeing how each valve will...
Control System Techniques in Equipment Design and Operations
A high level of automation and sophistication is required to control process parameters and detect equipment faults in today’s petrochemical plants. Join control system expert A.S. Rangwala and learn automatic control theory methods that enhance efficiency and provide operational safety by ensuring process parameters do not exceed design capability.
Applying Bus Technologies in Process Control
Ed Smigo
Fieldbus technologies have become increasingly popular in process control applications. This article highlights the practical applications and economics of various buses, so that an engineer can choose the best one for his or her process.
