Technological part

Installing absorption unit to capture SO2-gases from calcination of alum 5.000 kg / hr. The unit is replenished with hydrogen peroxide and sulfuric acid 45% produces.
Installing new calcining furnace including fluidization handling Al2O3 powder.
Pilot testing of heat recovery by heating the combustion air downstream from calcination of saving earth gas.
The absorption unit is connected to the existing distribution of water and energy, cooling water is air cooled by condenser.

 

Construction part:

For the location of the new furnaces were made in the current building Monocrystals.
By the building was built system of detention and emergency reservoirs for filling tank trucks, placing the structure for absorption unit and reservoirs of hydrogen peroxide and sulfuric acid.

Company INTECON provides documentation for building permit and realization of project as "turnkey supply".
