Under the background of “carbon peak and carbon neutrality”

traditional chemical enterprises are encountering challenges due to CO

2

emission limitations. CCUS（Carbon Capture

Utilization and Storage） technology emerges as a crucial strategy for addressing CO

2

emissions. To mitigate emissions at the source

chemical companies are turning to CO

2

flue gas capture and recovery technologies

while also exploring ways to integrate these efforts into a cost-effective CCUS industrial chain. To overcome the drawbacks

of traditional CO

2

flue gas recovery units

such as large land use

high construction costs

inflexibility

and lengthy construction times

the modular skid-mounted CO

2

recovery technology has been introduced. This innovative approach minimizes upfront investment and accelerates project timelines by modularizing the recovery process

allowing for 100% factory prefabrication and streamlined on-site assembly. The skid-mounted design efficiently organizes pipelines and valves

integrating equipment within each module onto skids

resulting in a fully modular skid-mounted CO

2

recovery unit. Field applications demonstrate significant advantages of the modular skid-mounted approach over conventional methods. For example

a 5×10

4

tons per year coal-to-hydrogen CO

2

flue gas recovery unit saw a 74.0% reduction in construction costs

a 75.2% decrease in required space

and a 50.0% shorter construction timeline

effectively meeting the objectives of cost reduction and expedited project completion.
