工艺原理：
采用变压吸附（简称PSA）工艺从含一氧化碳CO、氢气H2,、甲烷CH4、二氧化碳CO2等组分的混合气中提纯CO。原料气进入一段PSA装置，吸附除去CO2、水分及微量硫；脱碳后的净化气进入二段PSA装置，脱除H2、N2及CH4等杂质，吸附的CO经减压真空解吸作为产品输出。
Feed gas：
water gas、semi-water-gas、Regenerated Gas Washed with Copper、Texaco coal gasification
、blast
furnace gas、yellow phosphorus tail
gas、Carbon black tail gas
Other gas sources
Control mode and characteristics
：
Control mode: The SPA device is
controlled by the controller and meter. The controller can select DCS, FCS and
PLC control system according to the scale and control requirements of the SPA
device.
Characteristics: It not only realizes the
conventional control of the system, but also realizes the expert control and
adaptive optimization control of arbitrary combination and switching of
multiple towers, which not only improves the operational flexibility of the
device, but also ensures the long-term, stable and safe operation of the PSA
device.
