So I’m looking for some input from the community as to which would be best for recovery. We’ve been searching google and on here to Identify which would be best to use in recovery of a 70/30 butane/propane blend on a closed loop system that running 70# using a cmepol. Currently we are using a large recovery coil sitting in a 5gallon bucket of dry ice and iso.
We consume a lot of dry ice and because we run through a lot of dry ice that means a lot of co2 is sublimating in the lab and even with plenty of ventilation out of the lab and plenty of exhausting air out of the warehouse it’s always been a concern of built up co2. And of course there’s always the cost of a consumable like dry ice.
So we are looking for a solution to get rid of dry ice and go with a chiller and possible heat exchanger option. Do you have any suggestions? Or can you help point us in the right direction? Thank you in advance
