The technology of Purification CO by PSA

CO was purified from mixed gases containing carbon monoxide CO, hydrogen H2, methane CH4, carbon dioxide and CO2 by PSA process. The raw gas enters into a PSA device and absorbs CO2, moisture and trace sulfur. After decarburization, the purified gas enters the secondary PSA device to remove impurities such as H2, N2 and CH4, and the adsorbed CO is released as the product through vacuum decompression.

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.
