SIMULTANEOUS REMOVAL OF NOX AND SO2 THROUGH MOBILE BED CATALYTIC PROCESSES

Objective


Preliminary results indicate that the principle of economically removing both sulphur oxides and nitrogen oxides simultaneously from a single mobile-bed reactor has been established. The process involves the adsorption of toxic gases through a bed of copper based catalytic material to form copper sulphate. This is injected with ammonia which in turn catalyses the DeNOx reaction. The spent catalyst is treated with a reducing agent, returned to the top of the reactor and converted to copper oxide thereby initiating a new cycle.

Further studies are under way to optimize the process, ensure that the chemical reactions involved are completely understood, and that they can be contained over long periods of operation.
THE MAIN GOAL OF THE PROJECT IS TO SET UP A CATALYTIC PROCESS ABLE TO REDUCE THE SO2 AND NOX EMISSIONS FROM POWER PLANTS TO LEVELS LOWER THAN THE LEVELS REPORTED IN THE EEC PROPOSAL FOR YEAR 1995.

SO, THE PRINCIPAL OBJECTIVES ARE:
- TO IDENTIFY AND CHARACTERIZE A CATALYTIC SYSTEM ABLE TO SIMULTANEOUSLY REMOVE SO2 AND NOX FROM FLUE GASES.
- TO SET UP A MATHEMATICAL MODEL OF THE REACTION AND TO PERFORM THE FEASIBILITY STUDY.
