Inventor: KOCH CHRISTIAN DR ING
IPC: C01B32/50
Filed: 1976-02-12
Abstract: System for recovery of CO2 from air uses a solvent which absorbs the CO2 and which can be thermally regenerated. This is an alkazide soln. being the K salt of methyl-amino-propionic acid. This is dispersed as droplets in the air and absorbs the CO2 from the air. The CO2 is then recovered by stripping with steam in a desorption column having trays of very porous sintered material. The distributor is mounted in the upper part of the cooling tower of a power station above the water cooling zone. Below the soln. distributor is a perforated collection system for the soln. The distributor system consists of perforated flights which enhance the upwards motion of the air and throw the soln. radially from the centre to the outside. The air contains 0.03% CO2 and this is predicted to rise to 0.04% because of the increasing combustion of hydrocarbon fuels. Used partic. in power stations.
