Process and apparatus for cracking ammonia

Processes for cracking ammonia are improved by using heat generated in a compression unit that is used to compress PSA off gas being recycled to a PSA unit to pre-heat liquid ammonia prior to vaporization and cracking. The heat is transferred using a heat transfer fluid such as an aqueous solution c...

Zusammenfassung:	Processes for cracking ammonia are improved by using heat generated in a compression unit that is used to compress PSA off gas being recycled to a PSA unit to pre-heat liquid ammonia prior to vaporization and cracking. The heat is transferred using a heat transfer fluid such as an aqueous solution comprising from about 50 wt. % to about 60 wt. % of a glycol, e.g., ethylene glycol or propylene glycol.
