Advantages Features of Urea 2000plus

Advantages of the Urea 2000plus technology

  • Savings in investment costs due to the reduction in size and – for the pool reactor concept – also the number of high-pressure items
  • Operational advantages:
    • more stable level / pressure control
    • less sensitivity to changes in the load or the N/C ratio
    • fast capacity change of the plant due to self-regulating heat transfer characteristics
  • Reduced construction height, resulting in reduced construction costs
  • Improved heat transfer leading to reduced heat exchanger area

New features in recent plants using Urea 2000plus technology

  • The high-pressure section of recently-built urea plants are made of Safurex, a duplex steel specially developed for the Stamicarbon urea process by Sandvik, Sweden. This steel offers excellent corrosion resistance and high toughness and permits a reduction in the amount of added passivation air.
  • For plants with state-of-the-art capacities Uhde applies Flowserve centrifugal pumps in ammonia and carbamate high pressure service. These pumps were newly introduced for this application and lived up to expectations in the Qafco 4 fertilizer plant. They proved to be highly reliable and require minimum maintenance.

Common highlights for all CO2 stripping processes

  • Low energy consumption
  • High process efficiency leading to low raw material consumption figures
  • High on-stream times (reliability)
  • Low corrosion rates
  • High safety standards
  • Low emissions
  • Simple operation
  • Easy maintenance
