Abstract: Because liquid ammonia has great potential safety problems in transportation, storage and use, the ammonia supply by
liquid ammonia of denitrification system is gradually replaced by ammonia production of urea. This paper combed the resources
consumed in the operation of urea hydrolysis ammonia production process in detail, and calculated the consumption and cost of
resources during the normal operation of the system by taking the revamping of urea hydrolysis ammonia production project of 2×
330 MW units as an example, based on which, the direction of efforts to reduce the operation cost and the optimization mode of
system design were proposed.

Key words: liquid ammonia; urea hydrolysis; ammonia production; operating cost
