L FOR BUCHEN
high head of the FCC system was separated
by our cold welding specialists with the
help of the automated Buchen cold welding
process and lifted with a special 1,800 ton
crane. The dome was then safely cleaned
and improved in order to be able to be
setup again precisely with the crane.
Around 700 apparatuses like heat exchangers,
columns, air coolers, containers, filters
and reactors were cleaned in record time
by up to 300 employees from the Buchen
Group between the middle of February
and end of March. The focus here was
always on the optimal and goal-oriented
application of specialized technology and
qualified personnel under compliance with
the strictest safety measures for people and
environment.
Altogether 40 high pressure pumps were
used, which cleaned components and
containers with 600 to 1200 bar of water
pressure. A variety of suction vehicles vacuumed
the remaining deposits, liquids and
sludge after cleaning from pits, containers
and canals. With air displacement trucks,
dry deposits and residues – whether fine
dust or fist-size bricks of coke – were vacuumed
through dozens of meters of hoses
and then properly disposed of. Devices
for the automated, remote-controlled inner
and outer area high pressure water
jet cleaning of heat exchangers and other
components provided for high efficiency
with the best cleaning results. Dumpers,
forklifts and transport vehicles were coordinated
by Buchen in order to make sure that
all waste could be disposed of during a
shutdown. Personnel from all regions and
the specialized subsidiaries of the Buchen
Group supported the Buchen employees
from Karlsruhe.
In order to guarantee the constant reinforcement
of equipment and tool, Buchen
had their own magazine container on site
where the required tools and materials can
be submitted around the clock. An intact
and complete equipment is the basis for
safe and punctual work.
Work safety has the highest priority during
the execution of shutdown. Regular safety
meetings between the construction leaders
and the safety specialists of all partner companies
were one of the many measures in
the safety concept of the MiRO. This also
included a competition where all participating
companies were evaluated on a weekly
basis in regards to their safety behavior.
The Buchen Group also received a prize for
model safety behavior during a week.
