Abstract
The article deals with the study on the efficiency of units for porous ammonium nitrate
production. The ways which increase the effective implementation of energy resources are determined
by including the ejector recycling module, heat and mass exchangers that utilize principles of
regenerative indirect evaporative cooling, and the sub-atmospheric inverse Brayton cycle. Mixed
exergy analysis evaluates all flows of the system contour as those of the same value. The target
parameter for determining the efficiency of both systems is the ratio of the unit’s productivity to
the exergy expenditures to produce the unit mass of the product. As a result, it is found that the
mentioned devices and units enable to increase the efficiency of the basic scheme by 87%.
