摘要：

Pressure　and　Temperature　Swing　Adsorption　(PTSA)　is　an　appealing　purification　technology　for　removing　low　CO2　concentration　from　confined　space　potentially.　In　this　work,　a　systematic　method　integrating　dynamic　process　simulation,　sensitivity　analysis,　process　optimization,　and　energy　consumption　assessment　was　established　to　investigate　a　PTSA　process　of　low　CO2　concentration　separation　in　the　confined　space　using　two　adsorbents　(Zeolite　13X　and　NaUSY).　The　dual　site　Langmuir　adsorption　isothermal　models　of　N2　and　CO2　were　established,　and　calculated　results　showed　good　agreement　with　the　experimental　data.　After　parametric　sensitivity　analysis,　key　operational　parameters　(i.e.　adsorption　pressure,　desorption　pressure,　regeneration　temperature　and　P/F　ratio)　were　optimized　to　achieve　minimum　process　energy　consumption.　Those　results　indicated　that　Zeolite　13X　was　a　good　candidate　for　separating　low　concentration　CO2　from　confined　space　with　lower　energy　consumption　(55.03　kJ·Nm−3　N2).　The　simulation　result　can　provide　a　novel　strategy　for　removing　low　CO2　concentration　from　confined　space.　©　2021　Elsevier　B.V.
