  • Level Blog: Avoiding Corrosion while Increasing Urea Production

    Jim Cahill
    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 reactor, the shell…

  • Analytical Experts Blog: Gas Chromatograph Installation Considerations

    Jim Cahill
    Gas chromatographs (GCs) are used to analyze natural gas streams to identify the hydrocarbon components in order to determine the energy content of the gas. Natural gas is typically sold based on the amount of this energy delivered. The quantity of energy delivered is calculated by multiplying the gas volume per unit time by the heating value (BTU) per unit volume. Some standard applications for GCs include: Standard…
