What are ceramic filters?

Many types of ceramic products used for filtration

Honeycomb filters – engines

Dense ceramics used in high pressure high temperature applications

We are focussing on products made with ceramic or mineral fibres –formed into tubes/candles

Compatible with standard bag filter design concepts

Good with “high” dust duties

Ceramic filter features

Highly porous

One piece construction

High Efficiency particulate removal

Chemically almost inert

High temperature resistance

Longest product 3 meters long

Rigid otherwise works like a fabric bag

Used with a sorbent can remove acid gases such as SOx and HCl

Combined with a catalyst can remove pollutants such as NOx and dioxins

Dust removal

Some particulate

penetrates the surface and

acts as a barrier to further

dust penetration

Dust accumulates on the

surface and is removed by

cleaning pulses

Non-blinding

High efficiency

Acid gas removal

Sorbent such as hydrated lime

Ca(OH)2 added as particulate

to gas stream

Sorbent accumulates on the

filter element surface

Pollutants such as SOx and

HCl must pass through dust

cake, and are neutralised by

sorbent

Spent sorbent is removed by

cleaning pulses

Catalyst filter for DeNOx

Catalyst distributed

throughout filter element

structure

Ammonia added to gas stream

to remove NOx

Pollutants must pass through

filter and, in doing so, come

into contact with the catalyst

NOx and dioxins are converted

into harmless products, such

as nitrogen and water

Advantages – eliminates catalyst failure modes

Catalyst is protected against the poisons such as As Se Na and K because dust stays on filter surface

Catalyst is protected against dust blockage and blinding

Catalyst life is extended >5 years expected

Catalyst evenly distributed

Filter properties recap

Features Benefits

Ceramic composition Chemically inert with HF only known hazard

Maximum temperature of operation 900oC

Filter made from ceramic

fibres

The use of fibres gives the best balance of high efficiency and resistance to flow

Rigid filter element A support cage is not required

A surface dust layer provides high efficiency dust removal. Less than 2 mg/Nm3 is typical.

Non-blinding due to the surface dust layer, which gives long product life. 5 years and over

is not untypical.

Small fibre diameter and surface dust layer ensures that even submicron particulates are

captured.

The use of a sorbent gives an excellent bed for acid gas removal. High removal efficiencies

can be obtained at higher temperatures of operation, with greater than 90% efficiencies

readily achievable.

Manufactured in one piece No weak points such as bag stitching seams

Tubular shape Compatible with standard bag house designs

Catalyst embedded into

the filter element

Catalyst has high conversion efficiency for NOx and organic compounds

Optimal operation temperature of 350oc

Filter prevents poisoning of catalyst

Filter prevents masking of catalyst by dust particles

No chemical reaction between catalyst and ceramic filter

Nano sized catalyst particles present highly active catalyst sites

High performance achieved through no diffusion restriction
