The ISPRA MARK 13A process for flue gas desulphurisation is a direct spin-off from the work carried out during 1975-1983 in the framework of the Hydrogen Energy Programme. It is also the largest technologically realised process set-up of this type. A pilot plant with a capacity of 32000 Nm3/h was built and successfully operated. The paper describes the evolution of this flue gas desulphurisation process from the basic idea to the industrial scale pilot plant. A promising new denoxing process is described, for which the production and application of hydrogen is an important feature.
