ABSTRACT:
A process and a plant are disclosed whereby nitric acid is produced by the catalytic combustion of ammonia with air to form nitrous gases which are contacted with water in an absorption zone to form nitric acid. Gas flow into and through the plant is maintained by a compressor system powered by turbines that are propelled by the heat energy released during ammonia combustion. In accordance with the present invention, a portion of the ammonia combustion heat energy is stored using heat accumulating means positioned at various possible locations throughout the system. Such stored heat provides a thermal energy reserve available to power the compressor turbines for a short period of time in the event that ammonia combustion is discontinued.
