Abstract
The Walther process for the desulphurization of flue gases was developed with the aim of establishing a desulphurization method with the following features:
This chapter briefly describes:
-
avoidance of waste water and other waste products
-
production of the marketable nitrogen fertilizer ammonium sulphate from the sulphur dioxide contained in the flue gases
-
reheating the clean gases without external heating energy
These important characteristics of the Walther process were fist demon-strated in 1978 in a pilot plant for a throughput of 20,000 Nm3 /h.
