The carbon dioxide in the biogas produced by the anaerobic fermentation of urban food waste is efficiently recovered and purified, turning “carbon emissions” into “carbon sources” to achieve high-value utilization of waste resources.
- Customized process combination
Adopting the three-stage process of “pretreatment + pressure swing adsorption + refined liquefaction”:
- Pretreatment unit: desulfurization, dehydration, and impurity removal to ensure stable operation of subsequent equipment
- Adsorption separation unit: four-tower PSA system, CO₂ recovery rate >94%
- Liquefaction and purification unit: double-stage refrigeration, reaching food-grade standards
2.Energy efficiency optimization design
- Use waste heat from biogas power generation to drive the regeneration process, reducing energy consumption by 30%
- Intelligent load adjustment to adapt to biogas production fluctuations
- Run the liquefaction unit during off-peak hours to save electricity costs
3.Intelligent control
- Fully automated operation, remote monitoring platform
- Predictive maintenance system to reduce unplanned downtime
- Real-time data viewing on mobile terminal
