THERMODYNAMIC SIMULATION OF CONCENTRATED STEAM-AMMONIA MIXTURE COMBUSTION

摘要

Coking gas is purified from ammonia with water and a circulating phosphate method [1, 2], in which the steam-ammonia mixture (SAM) is concentrated by condensation and desorption before passage to the combustion reactor. The ammonia content in the SAM supplied from the desorber to the combustion unit can be kept constant within the range 40-80 percent by regulating the desorption conditions. The reactor receives not only the steam-ammonia mixture and the coking gas but also sulfur-bearing impurities, which are oxidized along with the ammonia.
