摘要

"VASE FOR CONTINUOUS GAS-LIQUID CONTACT, AND PROCESSES TO INCREASE CONTACT BETWEEN A LIQUID AND GAS AND FOR THE PRECIPITATED CALCIUM CARBONATE PRODUCTION". A process and apparatus for improving contact between a liquid and a reactant gas by moving the liquid in a serpentine path that moves horizontally and vertically through individual chambers or stations in an elongated tank or reactor and introducing a reactant gas into the liquid at a time. one or more of the stations or chambers as liquid moves through the tank or reactor.
