Many plants depend for their survival on improving efficiency to make them competitive with more recent plants built according to the most up-to-date principles. Casale has developed technologies and know-how to increase the efficiency of the most energy-consuming sections of the plant.

Different modifications can be done to improve the energy-efficiency of an ammonia plant, concentrating on reducing specific NG consumption, steam import from the utilities and electric power consumption.

Modifications are focused on the sections where changes could provide significant energy saving at a reasonable capital cost. Normally, main plant limitations are:

  • High primary reformer stack temperature
  • High specific energy consumption in the CO2 removal section
  • Overloaded synthesis loop
  • Machines close to their limits

All the technologies that are applied in Casale plant revamping are developed in-house and patented. The success of Casale lies in the capability to develop the most advanced, state-of-the-art technologies and apply these improvements to the plants to both increase the production, where required, and to decrease the energy consumption. Casale is proud of being a technology-oriented company, devoted to innovation.
