One look at the economic news and you see that trading relationships among countries are changing from longstanding norms. For manufacturers, this uncertainty requires flexibility to adapt to changing market conditions. In a Process Engineering article, Connectivity...
Author: Ana Gonzalez Hernandez In my previous post, I introduced the concept of resource efficiency: the integrated efficiency with which energy and materials are transformed in industrial processes. I mentioned that improvements in resource efficiency are considered...
As alternative energy sources and energy storage technologies continue to advance, will the decrease in transportation fuel demand be mitigated by the growth in petrochemical demand? At CERAWeek 2018, Emerson's Jamie Froedge joined a panel, Petrochemicals: Future...
Olefins, also known as alkenes, are unsaturated hydrocarbons, use to make many petrochemical products such as plastics. Olefin production, including ethylene, propylene and butadiene products, requires tight control for higher throughput, more energy efficient, and...
For a valve, zero leakage is defined as no visible leakage when tested at high pressure with water and low pressure with air according to existing international standards. Some of these seat leakage standards for control and isolation valves include ANSI/FCI 70-2/IEC...
The ethylene molecule consists of a double bond between carbon atoms and four hydrogen atoms bonded, two to each carbon atom. Per the Wikipedia Ethylene entry, it: …is widely used in the chemical industry, and its worldwide production (over 150 million tonnes in...
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...
