FAUDI for Petrobas
Maximum performance –
minimum filtration loss
One of the world‘s largest oil companies, Brazil‘s Petrobas
S.A., uses filter units from FAUDI in its REVAP refinery.
The fully-automatic and maintenance-free FAUDI modular
pump units are used in refineries to filter hydrocarbons.
Low-molecular hydrocarbons, rust and metal residues are
produced during the cracking processes that take place
in the refineries; these can damage the catalyst units. In
order to prevent this, a cleaning process using modular filter
systems must take place. However, this results in medium
being lost through flushing as it has to be used for flushing,
or an external medium has to be used. By using gas-assisted
backflushing, a maximum amount of filtrate can be obtained
without losing the medium itself through flushing. It is
this technique that is used in FAUDI‘s modular filter units.
During cleaning, the individual modules are first flushed with
medium or external medium and a gas buffer is then fed into
the module. Medium flushing loss is reduced to a minimum
since the modules no longer need to be fully flushed with
medium or external medium. The inert gas used in the
backflushing process is separated from the medium using a
gas separator. Petrobas is a technological leader in offshore
production and puts its complete trust in FAUDI‘s high level
of technical expertise in order to maintain this position.
