DuraTop®-Special Reformed
Packings
DuraTop® special reformed
packings are used, among other things, for covering catalyst beds. DuraTop® special
reformed packings can be added onto the top ball layer or even replace the top ball
layers. As the top layers on the catalyst beds, DuraTop® special reformed packings offer
the following advantages:
low pressure loss because of
large free gap volume
good pre-distribution of the
liquid and gaseous media, even before these reach the catalyst bed, as a result of the
open internal structure of the DuraTop® special reformed packing
the large specific surface
leads to an increased retention of any particulate impurities of the media before they
reach the catalyst bed.
