Abstract

[Objective

]

This study aims to investigate the applicable conditions and key operational parameters for an integrated compression

purification

decarbonization

and denitrification process applied to natural gas oxy-fuel combustion flue gas. The research seeks to clarify the technical feasibility and performance boundaries of this process for achieving efficient carbon dioxide(CO

) capture coupled with deep removal of nitrogen oxides(NO

)

providing a practical solution for integrated carbon capture and pollutant control in natural gas oxy-fuel combustion systems. [Met

hods

]

A steady-state process model for the compression and purification of oxy-fuel combustion flue gas was developed using Aspen Plus

which accurately describes the thermodynamic behavior of the high-pressure

multi-component gas mixture. Through systematic simulation and parametric sensitivity analysis

the study focused on the combined effects of the initial CO

volume fraction in the flue gas and the system operating pressure on process performance. Key performance indicators evaluated include the CO

recovery rate

liquid CO

product purity

removal efficiency

and specific comprehensive power consumption. [Results

]

The simulation results establish a definitive and strong correlation between the CO

recovery efficiency and the initial concentration of CO

in the flue gas. A clear technical threshold is identified: to attain a CO

recovery rate of 80% or higher

the initial CO

volume fraction must exceed 60%. This finding defines a primary applicability criterion for the compression-purification approach. Subsequent analysis concentrated on flue gas compositions meeting this highconcentration criterion(60% CO

). Within this domain

the system operating pressure emerges as the most influential parameter governing the synergistic relationship between NO

abatement and CO

purification efficiency. Detailed parametric optimization reveals a distinct optimal operating pressure of 2.8 MPa. Operating at this pressure enables the process to achieve superior performance across all key metrics: the NO

removal efficiency surpasses 94%

the purified liquid CO

product attains a purity of 95% or higher

and the target CO

recovery rate of ≥80% is reliably maintained. Crucially

this operating point corresponds precisely to the minimum in specific power consumption

which is quantified at 120.1 kW·h per ton of CO

captured. This represents an optimal tra

de-off

balancing high environmental performance with minimized energy penalty

a critical factor for economic feasibility. [Conclusion

]

The compression and purification technology is suitable for treating oxy-fuel combustion flue gas with a high initial CO

volume fraction(60%). By optimizing the system pressure to 2.8 MPa

efficient CO

capture and deep NO

removal can be achieved simultaneously with low energy consumption. This study clarifies the key performance thresholds and optimal operating parameters for this integrated process

providing a concrete and feasible technical solution for achieving pollution reduction

carbon mitigation

and resource utilization in natural gas oxy-fuel combustion systems.
