Hot flue gases with a temperature of 265-285°C from the wet process acid conversion column enter the WSA acid condenser through the lower acid collection tank, where the acid production process is completed.
In the acid condenser, the flue gases undergo gas-liquid transformation to form hot concentrated sulfuric acid with a temperature of about 245°C. This concentrated sulfuric acid drains to the lower acid collection tank where it is collected, after which it is directed to the sulfuric acid circulation system via an acid drain hose.
