Abstract

PURPOSE: To improve regeneration conditions of an adsorption tower, to decrease the required quantity of an adsorbent and to miniaturize the adsorbing tower by incorporating a preregeneration process using excess waste gas discharging to the atmosphere before a regeneration process in an adsorption tower changeover process.
CONSTITUTION: After the greater part of waste gas is fed as regeneration gas for an adsorption tower 4 during the regeneration process through a regeneration gas inlet valve 19 to the adsorption tower 4 where moisture and carbon dioxide are adsorbed, it is discharged through a regeneration gas outlet valve 22 to the atmosphere. Here before a regeneration process, a preregeneration process is performed. The preregeneration is being previously regenerated extra by making flow excess waste gas discharged to the atmosphere when in the depressurized and pressurized states only for the time obtained by shortening the depressurization and pressurization time. That is to say, the depressurization and pressurization time in the adsorption tower changeover process is shortened to the utmost, causing the preregeneration time to be secured. And during the preregeneration, a discharge valve 29 discharging the excess waste gas is fully opened and the whole waste gas is used as regeneration gas and preregeneration gas.
