CO2 Recovery Plant from Dry Ice Production

SINOCEAN TECHNOLOGY POWER

Description

 

Dry ice is produced by suddenly expanding pressurized liquid CO2 under atmospheric pressure. The general conversion ratio will be approx. 40 to 45% of dry ice. In simple words: out of 100kg liquid CO2 only 40-45kg will be dry ice and the rest is normally lost as CO2 gas to the atmosphere. With a CO2 Revert Recovery System, however, most of the CO2 can be recovered which leads to a final conversion rate of approx. 90-95 %. This way, the dry ice production costs are reduced up to 50 %.

 

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. Lastly liquid co2 goes into co2 tank.
