CO2 recycling
Thread Content
Gentlemen, there is currently 1.76 million tons of CO2 waste gas per year, of which 1.45 million tons are CO2, accounting for 75%; the remainder is nitrogen and trace amounts of water. Now, to recover this CO2 into dry ice, what process would be suitable? What is the investment required, and is there any value in carrying out this recovery? Additionally, if any equipment manufacturers have devices that can achieve this recycling purpose, we would appreciate it if you could provide your contact information. Thank you!
The purity is only 75% – I feel a lot of pressure； I specialize in carbon dioxide purification, but generally liquid distillation is used for this purpose; for concentrations that are relatively low, I don’t think it’s very cost-effective. 314357482@qq.com
