Ettlingen, October 2002
October 2002 - The styrol industry is processing a large number of raw
materials to be used in the automobile-, electronic- and packaging industry.
The core of the styrol production plant is an extruder which is operated under
vacuum.
Common vacuum pumps or steam ejectors could not produce the vacuum for long
time as scaling and collection of dirt always caused trouble.
With a new combination of ejectors and mixing condensers GEA Jet Pumps has
now developed a system which is insensible to scaling and dirt and enables a
trouble-free operation of the vacuum pumps for a long period. An additional
benefit is the reduction of waste water as the system operates with closed
cooling water loop.
Two plants are already successfully in operation at well-known customers and
the commissioning of the third plant will take place soon.
