    Reliable Control Valve Performance in Ethylene Production

    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 more reliable operations. In an article from The Chemical Engineer, Increasing Ethylene Conversion and Plant Reliability , Emerson’s Blake Coleman...

    Reliable Switching Valves for Ethylene Production Molecular Sieve Applications

    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 60534-4, API 598, MSS SP-61 and ISO 5208. ANSI/FCI 70-2 and IEC 60534-4. Emerson’s Vanessa triple offset valves (TOVs) were the first to provide bidirectional...

    Laser Gas Analyzers for Optimizing Ethylene Production

    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 2016 [5] ) exceeds that of any other organic compound . [6] [7] Much of this production goes toward polyethylene , a widely used plastic containing polymer...

    Optimizing Distillation for Increased Methanol Capacity

    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 cost...

    Avoiding Corrosion while Increasing Urea Production

    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

    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...

    Urea Production Automation Challenges

    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 p...

    Opportunities in the Petrochemical Industry

    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...
