Optimizing Distillation for Increased Methanol Capacity

Jim Cahill

James Gremillion 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 materials, etc. In designing the distillation section, for example, the licensor did a calculation of how many theoretical trays were needed…

Avoiding Corrosion while Increasing Urea Production

Jim Cahill

James Gremillion 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 to 200 bar ) in a special reactor. The urea reactor is a reactor vessel inside a protective shell. Should there be a leak in the…

Optimizing the Ammonia Production Process

Jim Cahill

James Gremillion 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 computer that had proven to be too difficult to do in the pneumatic and electronic controllers of the time. Ammonia production increased…

Urea Production Automation Challenges

Jim Cahill

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 balance throughput with efficiency and the quality of the urea produced. In a new whitepaper, 4 Solutions for Urea Automation Challenges , Emerson’s James…

Opportunities in the Petrochemical Industry

Jim Cahill

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 Shutdowns & Turnarounds conference will be happening. Each conference has a Twitter hashtag you can follow at #PEC16 and #GCST16 . I’ll be using these hashtags…

Outlook for Chemical and Specialty Chemical Manufacturers

Jim Cahill

The post Outlook for Chemical and Specialty Chemical Manufacturers appeared first on the Emerson Process Experts blog. 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. Peter Cox Director, Global Chemical Industry But what have been the implications for downstream producers…

Solving Thermal Oxidizer Interacting Loops

Jim Cahill

Sonal Gilani Chemical Industry Program Manager 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. James Beall Principal Process Control Consultant Emerson’s James Beall shared a second story on this thermal oxidizer equipment, which is used to destroy the waste gases containing…

Improving Energy Efficiency in Thermal Oxidizers

Jim Cahill

Sonal Gilani Chemical Industry Program Manager 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 high temperature is maintained for sufficient time to complete combustion to carbon dioxide and water.…

An Agrichem Blog: The 100th Birthday of the Ammonia Plant

jamesgremillion

One hundred years ago, next month, the first ammonia plant was built in Germany. Ready for a history lesson? Do you recall the airship (zeppelin) that burned in New Jersey in 1934? It was the Hindenburg and, although loss of life wasn't massive, it was, and still is, considered a major disaster. One of the questions I had as a youth was why the Germans stupidly used flammable hydrogen instead of inflammable helium…

An Agrichem Blog: Haldor Topsoe

jamesgremillion

AN AGRICHEM BLOG: There are three primary licensors of ammonia processes. The third largest in Uhde in Germany, the second is KBR in Houston and the first is Haldor Topsoe in Denmark. To many of us the name of that last company brings up images of catalysts rather than ammonia plants and indeed that's where Haldor Topsoe made its name, beginning in 1940 when the company developed an innovative catalyst to speed…

An Agrichem Blog - Nitrogen+Syngas Conference

jamesgremillion

I had the opportunity to attend the Nitrogen+Syngas conference in Berlin last week. Nitrogen+Syngas is a conference aimed at ammonia, urea, methanol and gas-to-liquids plants. One of the presenters, an executive from an Agrichemicals firm, spoke about the coming collapse of ammonia prices because of overbuilding. Right now, ammonia prices are at record highs and production costs in North America at record lows but,…
