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...

Improving Energy Efficiency in Thermal Oxidizers

Sonal Gilani Chemical Industry Program Manager Author: Sonal Gilani Thermal oxidizers are used to destroy the waste gases containing volatile organic compounds (VOC) and volatile hazardous air pollutants (HAP) by raising the temperature of the material above its auto ignition point in the presence of oxygen. The high temperature is maintained for sufficient time to complete combustion to carbon dioxide and water....
