Petrochemicals-a Growth Area for Hydrocarbons

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 pillar of growth for hydrocarbons?, to explore the role downstream hydrocarbons will play in overall demand. The panelists included leaders from Dow Chemical...

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...

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...
