| 摘 要： | 根据工艺过程中能量转化碳排放量为标准,对4种主要生物沼气处理方式即直接燃烧放空、制热供暖、发电和提纯压缩天然气的碳足迹进行对比分析,结果表明:采用PSA(Pressure Swing Adsorption)沼气提纯工艺技术,不仅能极大地降低碳排放量对温室效应的影响,还能通过能量的回收替代传统能源,实现巨大的碳减排量,具有理想的碳减排效益。

| Abstract: | The carbon footprints of four major biogas treatment ways were analyzed respectively based on carbon emissions standards in the energy conversion process.Such as direct firing,heat generation for heating,power generation,purification and compression natural gas.The results showed that purification technology of biogas by PSA(Pressure Swing Adsorption),not only greatly reduced the impact of greenhouse effects by carbon emissions;but also achieved significant carbon emission reductions through recovery of ene... |
