<strong>VocsiBox®</strong><br />
Regenerative Thermal Oxidation (RTO) of landfill gas with low calorific value and/or process<br />
air from mechanical-biological waste treatment plants (MBP)<br />
In the treatment of low calorific value gas and MBP process air <strong>VocsiBox®</strong> combines the simplicity of<br />
biofilters with the efficiency ratio of high-temperature combustion.<br />
<strong>VocsiBox®</strong> is the preferred solution for many applications: It produces low operating expenses and<br />
reduces greenhouse relevant emissions by 90 per cent. Exhaust emissions fall much below the TA-Luft<br />
limiting values.<br />
<strong>VocsiBox®</strong> also meets the new German emission requirements for process air from<br />
mechanical-biological waste treatment plants. This has clearly been proven by a BMBF research<br />
project in the year 2002 carried out at the Bassum waste treatment plant.<br />

The research project at the Bassum site provides excellent proof of the successful application of <strong>VocsiBox®</strong> in the treatment<br />
of process air from MBP plants. A large-scale facility for 50,000 m³/h started operation early in 2003.<br />
<strong>VocsiBox®</strong> works according to the priciple of regenerative thermal oxidation (RTO). Combustion is<br />
flameless and noncatalytic. The substances contained in the gas oxidize inside the reactor while the<br />
gas is flowing across a hot reaction bed at temperatures of about 1,000°C.<br />
After the starting phase the unit will soon operate autothermally even if the energy content of the<br />
process air is very low. Autothermal operation means that no extra energy needs to be supplied to<br />
keep the process going. Propane or biogas are frequently used in the event that auxiliary firing is<br />
necessary, e.g. for the treatment of contaminated process air.<br />
<strong>VocsiBox®</strong> in comparison to other current treatment processes<br />

In comparison to biofilters <strong>VocsiBox®</strong> excels by virtue of a high degree of methane reduction.<br />
Reliable performance control is possible independent of the quality of the crude gas.<br />
When compared to 3-bed facilities a major advantage of <strong>VocsiBox®</strong> is the minimization of nitrous<br />
oxide. This is due to the high temperatures applied in the process. Less requirement for insulation<br />
and a smaller number of movable parts are further benefits that underline the simplicity of the<br />
<strong>VocsiBox®</strong> process.<br />
Individual design<br />
It is possible to design a <strong>VocsiBox®</strong> tailor-made for local requirements.<br />
If, for instance, landfill gas is available to serve as cost-efficient auxiliary gas for the treatment of<br />
MBP process air the <strong>VocsiBox®</strong> reactor will be designed with a smaller thermal efficiency ratio. This<br />
reduces the cost of investment.<br />
Should it be necessary, however, to use propane an an auxiliary gas the unit will be optimized in a<br />
way to guarantee maximum thermal efficiency and to keep the running cost low.<br />
