Ispra MARK 13A process for flue desulphurisation
The Ispra Mark 13A process for flue gas desulphurisation is a patented method of removing sulphur dioxide from flue gases, particularly in fossil-fuel-fired power stations. The process was invented and developed at the JRC Ispra Establishment. It is a direct spin-off from the former hydrogen energy research programme. The process is a cycle based on the oxidation of sulphur dioxide to sulphuric acid by bromine and the subsequent recovery of bromine by electrolysis of hydrobromic acid with formation of hydrogen. Potential advantages of this process are: the sulphuric acid and hydrogen produced are valuable chemicals which can be marketed or reutilised; all reactants are generated inside the process so that the disposal of solid products and waste water is not required; and the reaction takes place in the liquid phase which allows high reaction rates and small equipment volumes, probably leading to lower investment and operation costs. The construction of the pilot plant is in progress. Cold tests (eg running of reactants, leak tests, etc.) started at the end of July. The commissioning and start-up procedure proceeded during August and September. Hot start-up and start of the operation with hot flue gases will be performed successively.
