Dry gas seals eliminate oil contamination risks in ammonia process, reduce maintenance, handle higher pressures, and provide lower leakage rates compared to traditional oil seals.
Nitrogen is the standard buffer gas as it's inert, prevents ammonia decomposition, and maintains proper pressure differentials. Some systems use processed synthesis gas.
