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.
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...
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.
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.
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...
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.
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.
