ACES21 provides both energy saving and plant cost reduction in urea production supported by the following features:
- Uniquely optimized process parameters of urea synthesis process under the milder operating conditions combined with multiple heat integration in downstream process realizes remarkable reduction in energy consumption in urea production process.
- Forced circulation in synthesis loop by HP ejector without gravity flow provides compact and low-rise layout of plant
- Two stage urea synthesis in the Vertical Submerged. Carbamate Condenser (VSCC) and in the reactor lessens number and volume of HP equipment in urea synthesis loop.
- 30 to 40% energy saving compared to conventional production technologies- 10 to 20% energy saving compared to modern production technologies
On top of substantial savings due to energy conservation, the following can be achieved:- Low investment cost (construction and equipment).- Easy operation and high on-stream factor- Low maintenance cost (due to factors such as milder operating condition)- Less corrosion- Clean effluents
Typical EPC period: 3 years
12 implementations in 9 countries (Indonesia, China, Trinidad & Tobago, Iran, Venezuela, Bolivia, Nigeria, etc.)
