Recovery Speed - A Thermodynamic Approach

Dry Ice has Enthalpy of sublimation of 571kJ/kg. If we’re interested only in the condensing of the gas that’s just been evaporated we only need to look at the Required Power for Boiling column. I’m gonna throw economy in there just cause—let’s assume dry ice is $1/lb @ 1lb/min for Butane, you will lose 0.005 kg/s of dry ice (about 18kg/hr or 40lbs/hr) This means every hour you’re paying $40 for dry ice only. And for each shift $320. If you run 300/365 days a year that’s equivalent to $96,000…
