Inventor: YOSHIDA HARUHIKO
IPC: C01B3/56
Filed: 1984-10-18
Abstract: PURPOSE:To increase the absorption efficiency of CO by using a solid-like CO absorbent to remove CO selectively from gaseous mixture and recovering the gaseous mixture in a pressurized state. CONSTITUTION:Gaseous raw material 1 is elevated in pressure by a compressor 4 and introduced into an absorption tower 5 and in paralleling thereto gas is introduced to a tower 8 finished with the dissociation from a tower 6 finished with absorption to make the pressure uniform. After finishing the pressure equalization, the gas incorporated in a tower 7 is purged and dissociated by the residual pressure of the tower 6 to discharge gaseous CO 3 to the outside of the system. Thereafter an absorption process is performed in the tower 8 and the towers 5, 7 are subjected to the pressure equalization and the dissociation process is performed in the tower 6 and these operations are repeated and the absorption process is again performed in the tower 5. By this method, since the half quantity of gaseous raw material is used for the rise in pressure and the residual half quantity is used for the purge and the dissociation gas, the recovery efficiency of gaseous product is increased.
