    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...
