When dry ice is produced the conversion rate from liquid CO2 to dry ice is approx. 40%. This means 60 % is lost to the atmosphere. This conversation rate is a physical fact and therefore, unfortunately, not to change. With a CO2 Revert Recovery System, however, most of the CO2 can be recovered which leads to a final conversion rate of approx. 80%. This way, the dry ice production costs are reduced up to 40%. Sinocean realizes that best product always improve customer's economic benefit so we invent our own CO2 revert recovery system.
When one or more units of dry ice machines are working, the co2 gas discharged from dry ice machine will be guided to precooler though gas pipe for recovering cold and then enters gas balloon. Then co2 from gas balloon with normal pressure goes into co2 compressor and becomes 2.5MPa. Then goes into purification tower to get rid of air or water by absorbing. And clean co2 gas goes into precooler and exchanges heat with low temperature expanded gas.
Then goes into liquefier and separator: liquified and gas-liquid separated, purified. Finally liquid co2 goes into co2 storage tank for reuse..
and we have successfully installed one 300kg/hour CO2 recovery equipment from dry ice production in Indonesia.
