Abstract

PURPOSE: To save heat energy and to reduce an amount of a cooling water for condensing S by a method wherein an adsorbing agent after SO2 adsorption is heated at a specific temp. and S vapor with a specific temp. generated when desorbed SO2 is reduced is utilized as a heat source for SO2 desorption.
CONSTITUTION: SO2 in an exhaust gas is adsorbed by an adsorbing agent 4 comprising activated coal or semi-code until near saturated point thereof and above described adsorbing agent 4 is continuously taken out to a desorbing device 2 and heated to 300W400°C by a converting gas 14 with 800W900°C supplied to an external heating portion 6 to discharge adsorbed SO2 as a concentrated gas 13 and this gas i introduced to a S converter 3. The converter 3 packed with semi-coke 16 or the like is heated to 800W900°C by a fuel 20 and the SO2 gas 13 is reduced and converted to S vapor, thereafter the converted gas 14 with a temp. of 800W900°C is supplied to the aforementioned heating portion 6. As a result, S vapor is cooled by heat exchanging with the adsorbing agent 4 and an amount of a cooling water in a condenser 17 is reduced as well as a heat source at the desportion tower 2 is economized.
