Compressors and Systems<br />
Biogas backfeed<br />
sure. This feeds the processed biomethane<br />
into a 4 bar network, which is<br />
used in the brewing process at the<br />
brewery.<br />

After compression, the biomethane<br />
is re-cleaned via special filter<br />
systems and cooled down to a gas<br />
temperature of around 20°C using<br />
a chiller, as the pipes in the brewery<br />
process are made of temperaturesensitive<br />
PE. If the extraction during<br />
the brewing process is too low, the<br />
second compressor, a water-cooled<br />
CS23.8-37 medium-pressure compressor,<br />
switches over fully automatically.<br />
This high-pressure booster, developed<br />
by BAUER KOMPRESSOREN,<br />
makes it possible to handle high inlet<br />
pressure without reducing it. This<br />
operating mode is particularly energy-efficient<br />
and reduces energy consumption.<br />
Specially developed control<br />
and valve technology ensures<br />
uninterrupted operation. The compressors<br />
are housed in heated and<br />
ventilated containers, allowing them<br />
to operate in highly variable outdoor<br />
conditions.<br />

Gösser Bräu has added another important<br />
building block to its sustainability<br />
strategy with the commissioning<br />
of the fully installed systems<br />
following final acceptance.<br />
