Reactogard V Catalyst Protection Filters
How filter works...
Filter banks run in parallel, with each bank handling a portion of the total process flow.
Unfiltered liquid enters each bank via the inlet, and is distributed evenly to each filter housing.
The liquid flows from the outside of the element to the inside, depositing contaminants on the outside.
Clean liquid exits each bank via the outlet
As contaminants collect on the filter elements, the pressure differential increases.
When the pressure differential reaches a controlled set point on one bank of filters, a pressure switch signals the master controller to isolate the bank and begin the backwash cycle.
Systems are backwashed using filtered liquid or by introducing a separate backwash liquid.
How backwashing (cleaning) works...
When cleaning is required, the system operates without interruption.
A single filter bank that required cleaning is momentarily isolated from the feed flow and purged as the application required.
Then, each filter element on that bank is cleaned sequentially. This method assures that the total backwash energy is directed to individual.
Diverter chamber with precision proximity switch efficiently distributes material flow with fewer moving parts
Other system features include...
- Flanged valves (vs. socket welded valves) in standard ANSI dimensions simplify serviceability and replacement.
- Hardened alloy valve seats offer 4-5 times the life of carbon graphite.
- Actuators are located on valves so there are no mechanical linkages to maintain or adjustments to make.
- All components flanged for enhanced serviceability.
- Systems easily forward purge adaptable when handling high sulphur feeds.
- Programmable Logic Control (PLC) with electronic interface to control rooms provides control flexibility and reliability.

Why Low Flux Rates Are Important
Flux rate is the flow through a specific filter area. When this is lowered, so is the velocity of the liquid and solids going to the filter media.
As a result, the solid particles lie on the surface of the media, and create a porous particulate cake.
This improves efficiencies in particle removal while allowing liquid to pass, providing longer periods between filter cleaning.
What are design flux rates?
Design flux rates are application specific. When filtering heavy feedstock's, flux rates of 1 to 2 gpm/ft2 (40 - 80 lpm/m2) are recommended.
In addition, when filtering lighter hydrocarbons, flux rates are generally higher
