Issue 50/2013 - SGL's new porous graphite reactor enables sustainable halogenated waste gas

SGL Group has launched its new DIABON?porous reactor, once again innovating
in the field of waste gas treatment.

Conventional exhaust gas combustion plants require continuous operation to prevent corrosion
.
Today, as SGRIGA's corrosion-resistant specialty graphite materials are gradually being promoted, conventional units will gradually be withdrawn from the market
.
At the same time, the corresponding maintenance intervals and extended product service life will further shorten the payback period
.
Another advantage of the reactor is that its compact design reduces the footprint
by up to 60%.
The reduced heat capacity and the unique performance of DIABON?cream effectively reduce system start-up and downtime from hours to minutes
.
For the first time, this start-stop mode enables an on-demand exhaust gas treatment process that reduces energy consumption by more than 50 percent
.

There is a growing demand in the chemical industry for sustainable solutions for the treatment and recovery of corrosive waste gases, with one of the main focuses being the efficient recovery
of fluorine or chlorine-containing waste gases.
At present, these exhaust gas recovery is mainly achieved in conventional combustion chambers, but the combustion chamber takes longer to warm up and is prone to corrosion
during start-up and shutdown.
The DIABONÖNE porous reactor can be expanded by unit modules to form hydrogen fluoride or hydrogen chloride recovery units for recycling in the same process
