PROCEDURES FOR THE TRAINING AND RECOVERY OF CARBON ACID GAS FROM A GAS EMISSION BY ABSORPTION.

摘要

A process for separating and recovering highly pure carbonic acid gas from a gas mixture by adsorption, which comprises subjecting a wet gas mixture containing carbonic acid gas to an adsorption step, a washing step, a desorption step and a pressurising step using a pressure-vibration type of adsorption-and-separation apparatus constituted of an adsorbing chamber filled with alumina gel and zeolite.
