Wedge Wire Filter Elemeents From Filtration Group
We represent Filtration group USA for their range of wedge wire filter elements.
These are ideally 20 and 25 micron filter elements used in automatic back was feed filters in
➤ Hydrotreaters
➤ Hydrocrackers
➤ Coker units.
The filter elements are used in housings of automatic backwash filter housings.
Some case studies
Filtration group has provided increased filtration area for a competitors filter system in a Hydrocraker
unit. The filtration surface area was increased by @ 80% only by changing the filter elements. This
significantly increased the time between backwashes. Same foot print, same housings and same valves were
used.
FG can also supply retrofit wedge wire filter elements for another competitors filter system (DHDS Unit)
that were using mesh type filter cartridges. The wedge wire filter elements had to be replaced frequently
requiring frequent opening of housings, waste of few volumes of filtration medium and disposal of clogged
filter cartridges.
Salient features
Filtration group does CFD study and has metered plates on the filter housings to ensure
most effective
backwash using a given backwash volume. Thereby ensuring clean filter elements before the start of
filtration cycle. This helps prolong time between backwashes and thereby lesser wastage for recycle and
reprocessing.
Our wedge wires are suitable for insitu steam backwash. Occasional manual steam backwash
helps in
dislodging asphaltenes (especially from coker streams in lower temperatures). This allows return of clean
delta P. The supply steam conditions, duration can be advised by FG.
This will also need some study to see downstream piping (valves) study to see if they can handle the steam
temperature.
Engineering support and advise on various mix of fluid streams to enhance time between backwashes
etc.
RUGGED ROBUST wedge wire elements that have higher design collapsible and burst pressure.
