In order to improve the economy of urea hydrolysis process in thermal power plants

the experiments of producing ammonia by high concentration urea hydrolysis were conducted.The operating characteristics of the hydrolysis reactor under conditions with different feed concentrations were compared.The results show that

when the urea concentration in feed was increased

the urea concentration in the reactor and the ammonia concentration in the product gas increased

while the heat consumption decreased.The risk of corrosion and crystallization blockage also increased in high concentration.The urea concentration in feed had no obvious effect on frequency factor and activation energy of the urea hydrolysis reaction.
