How are companies in the chemical processing industries looking at Industrial Internet of Things technologies to improve their operations? This question was the focus of a Chemical Engineering article, The Digital Transformation in the CPI. The article opens...
The American Fuel & Petrochemical Manufacturers (AFPM) Annual Meeting is rapidly approaching—March 19-21 in San Antonio Texas. It is: …the world's premier refining meeting, assembling key executives, decision-makers, and technical experts from refining businesses,...
Author: James Gremillion When the process licensor designed your methanol plant, everything fit together to exactly produce the nameplate amount of methanol yearly. In the design there were necessary tradeoffs made because of costs, physical size, availability of...
Author: James Gremillion One of the key problems urea plants face is corrosion. The corrosion problem rests with one chemical produced by the urea process, ammonium carbamate. Ammonium carbamate is produced by reacting ammonia and carbon dioxide at high pressures (up...
Author: James Gremillion One of the earliest applications of "computer control", a now archaic term, on an ammonia plant was done in 1969 by Weissenfelder and Shah of Borden Chemical and IBM respectively. They were able to implement advanced control schemes in a...
Urea is a key component in nitrogen-rich fertilizers. Typically, the urea production process begins with hydrogen from natural gas and nitrogen in the air to produce ammonia. Urea is produced from the combination of ammonia and carbon dioxide. Urea producers must...
The petrochemical industry has benefitted from the huge supply increase of natural gas and liquids from shale gas here in the U.S. I'm in New Orleans for the next few days at the Petrochemical Engineering & Construction conference. Simultaneously the Gulf Coast...
In the news every day we see the changes in economic activity in the upstream oil & gas exploration and production business caused by the significant drop in oil prices over the past several months. But what have been the implications for downstream producers in...
Author: Sonal Gilani In an earlier post, Improving Energy Efficiency in Thermal Oxidizers, I highlighted how switching control loops from manual to automatic mode improved overall efficiency. Emerson's James Beall shared a second story on this thermal oxidizer...
Author: Sonal Gilani Thermal oxidizers are used to destroy the waste gases containing volatile organic compounds (VOC) and volatile hazardous air pollutants (HAP) by raising the temperature of the material above its auto ignition point in the presence of oxygen. The...
Author: Mark Brewer I was asked by the engineers at a chemical manufacturing site here in the United Kingdom if I could have a quick look at a level control problem in a reactor coolant water drum. They have 2 very large reactors that generate a lot of waste heat that...
For manufacturers with energy intensive processes, such as the petrochemical industry, the shale oil and gas boom in North America has led to lower feedstock costs. In this short, 1:34 video, Emerson's James Beall describes some of the challenges faced by plants to...
