CATALYTIC GAS CLEANING

Since 1988, ELEX has been supplying installations for the catalytic cleaning of
gases. The process reduces toxic elements such as NOx, dioxin and furan and
hydrocarbon and ammonia in order to comply with the toughest requirements
worldwide and without producing residues that will require disposal.

The main areas of application are:

• Incineration of waste and refuse
• Incineration of sludge
• Incineration of hazardous waste
• Cement production
• Incineration of biomass
• Various other incineration processes

ELEX has developed special catalytic systems for waste and refuse incinerators that take into account the heterogeneous composition of the materials to be incinerated as well as the resulting flue gas components and gaseous pollutants, maximising the quality of flue gas cleaning.

In the case of cement production plants, however, the position of the SCR reactor within the process is of significance to achieve optimal effectiveness. In this process, which was patented by ELEX, the SCR reactor is located directly behind the heat exchanger, where the correct operating temperature for the SCR is provided by the system itself. So no additional energy is required, which would be the case if the SCR reactor was positioned elsewhere in the process.
