Ammonia energy consumption availability

More than 50% of the heat available in the reformer effluent is recovered and used in the reforming reaction. This results in energy consumption as low as 23.4 to 24.8 MM BTU (lower heating value - LHV) per short ton or 5.5 to 5.9 gigacalories (LHV) per metric ton. These values represent a 5% to 10% reduction in energy consumption relative to a conventional ammonia plant203. 

The AMV process scheme may be considered as a variation of the classical scheme with some unique features. It has been used as described in the design of one plant and- with some modifications to accommodate integration with a urea plant-in another plant. Experience from operation of a plant using the process has been reported in [417]. The expected energy consumption has been given as less than 7.0Gcal/MT of ammonia (for a plant located in a cold climate), but actual data are not available.
