Refrigerant, stripping nitrogen, depressurization
Circulating water, chiller, flash (stripping nitrogen)
Propylene refrigeration, cooling generated by system flash vaporization and stripping, water cooling.
Propylene refrigeration, cooling generated by system flash vaporization and stripping, water cooling.
Propylene refrigeration, cooling generated by system flash vaporization and stripping, water cooling.
(1) Hybrid refrigeration systems provide cooling capacity through liquid ammonia； (2) High-pressure CO2-enriched methanol liquid is cooled through flash desorption ； (3) Cooling capacity provided by the water cooler
The ammonia cooler provides cooling capacity, the water cooler provides cooling capacity, and the cooling capacity generated by the desorption and regeneration of methanol-rich liquid
NH3 cooler, CO2 separation, the reflux liquid drawn from the liquid nitrogen wash.
(Ammonia refrigeration), (acidic gas desorption), (water cooler), (throttling).
