CERAMIC HOT GAS FILTRATION PLANTS
APPROPRIATE FOR MULTIPLE INDUSTRIES

Does your incineration plant have to lower its emission levels?

Saubatech can assist your company to lower its emission levels, ensuring that you comply with the global emission regulation standard.

Our ceramic hot gas filters are used in incineration units and in biomass boilers, removing particulate to below 5 mg/m³. This is achieved through our dry gas scrubbing which removes acid gasses, dioxins, and heavy metals.

The majority of industrial waste management processes produce emissions, which are hazardous to your health and pollute the environment.

Most countries have instituted regulations that limit hazardous emissions, requiring these gasses to be filtered. These gasses reach several hundred degrees in temperature, which conventional bag-type filters cannot accommodate. This leaves ceramic hot gas filtration as the only reliable long-term solution.

Particulate Matter often consists of fine particles (PM 2.5), which are extremely harmful to people. PM 2.5 is able to pass through many conventional filters, with ceramic hot gas filtration offering the only reliable method of capturing hazardous waste emissions. Dry gas scrubbers are used in conjunction with ceramic filters, to either adsorb or neutralise other harmful products, such as: hydrogen chloride (HCl), sulphur dioxide (SO2), hydrogen fluoride (HF), lead (Pb), mercury (Hg) and dioxins.

Our ceramic filtration units work by drawing the flue gas through hollow ceramic filter elements, capturing particles on the filter wall. The structure of the filter elements is so fine, that it successfully captures PM 2.5.

The filter unit is split into “dirty” and “clean” compartments, with the flue gas entering on the “dirty” side and particulate matter being captured by the filter element. Clean air then passes from the filter element into the “clean side” and out to the stack.

The filter elements are periodically cleaned. Reverse pulse cleaning makes use of compressed air, allowing the built-up particles to be discharged into a collection bin.

Dry Gas
Scrubbing

Designed with gas scrubbing in mind, our hot gas filters effortlessly incorporate sodium bicarbonate and activated carbon scrubbing. This is used to neutralise acid gasses (namely: HCL, HF, SO2), whilst adsorbing dioxins and heavy metals such as mercury and lead.

Our hot gas filtration units are further designed for optimal performance of sodium bicarbonate for its effective range of 140°C to 450°C. Operating at higher velocities ensures that there is no additional need for reaction towers, or other ancillary equipment required for effective dry scrubbing. Filters are modelled using CFD software to ensure even distribution and retention of the scrubber.

Making use of dry gas scrubbing, at temperatures above 400°, prevent the reformation of dioxins. Using bag filters will not achieve this, as it operates between 140°C to 260°C.

Filter
Options

We currently provide three different filtration systems. MacroCeramic filters for high temperatures up to 900°C, Glosfume filters for up to 450°C for the lowest emissions, and Glosfume biomass filters.

Standard filter pods range from 3500 to 9800 Am³, with all filters being modular units which can be linked together for extremely large processes. The modular units allow for easier installation, lower transport costs, flexible installation footprint, high redundancy, and easy maintenance.

Benefits

Saubatech’s ceramic hot gas filtration plants are especially effective due to the ceramic elements being able to withstand temperatures of up to 1,000°C, compared to 140°C to 260°C for bag filters.

These are the advantages of our products:

  • Non-flammable.
  • Operating temperature of up to 450°C (Glosfume units) and 900°C (MacroCeramic), allowing for scrubbing at the most efficient temperatures and during almost all processes.
  • No need for reaction towers or cyclones.
  • Lowest emission level achieved with constant and reliable performance.
