Urea Highlights
World production of Urea is 158 million tons per year (2009 figure)
The present price of Urea is around 280 US$/t
The value of Urea is 45 000 million US$/year
Annual increased demand is 3-5 million tons
China, Thailand and other Far East countries have a deficit of Urea
Raw material for standard Urea plant is Natural gas
EP Urea plant
Investment for a standard Urea plant is twice as high as the investment for an EP Urea Plant
The EP Urea plant may use natural gas or any other syngas (from gasification) as raw material
The EP Urea plant has low or no emission of CO2 and other green house or toxic gases
In addition the EP plant has 40% lower operation and 50% smaller equipment cost compared to BAT Urea plants
Some advantages of the first stage EP process are listed below:
- Only water/steam is used as feed
- Temperature 100-400°C
- Not dependent of pressure
- Pure Nitrogen is produced
- High Space Velocities
- Catalyst is recyclable
Some advantages of the second stage EP process are listed below:
- Only Methane is used as feed
- Temperature 200-400°C
- Not dependent of pressure
- Pure CO + Hydrogen is produced (syngas)
- High Space Velocities
- Catalyst is recyclable
Production of Urea is much less expensive with the EP method than any other method used today due to:
- Reduced Operational Costs
- Reduced raw material demand
- Higher power efficiency
2. Lower investment
- Reduced mass flows
- Reduced number of equipment
3. Smaller equipment
- Reduced mass flows
- Lower temperature
4. Higher power efficiency
- Reduced mass flows
- Lower temperature
5. Close to zero CO2 emission
- Produced CO2 used as raw material in urea production
6. Close to zero emission of other green house gases (as 6 below)
- Close to zero emission of toxic gases like NOx and Sox
- Lower temperature
- Nitrogen and Oxygen not present during high temp reactions
Investment and operational costs
Basis for the operational cost is a natural gas price of 200 US$/t
6% interest over 10 years
Equipment delivered Western Europe
Urea capacity 500 000 tpy

Current Status
Initial laboratory tests conducted
Theoretical process calculations conducted
EP is seeking partners to develop the process
The process has the potential to revolutionize the hydrogen, ammonia and fertilizer production
