High-effi ciency Gas Cleaning Systems are vital for the reliable operation and long campaign life of high temperature hot blast systems and steam generation facilities, and allow the opera-tors to meet the relevant pollution control standards.
Thanks to the expertise of Paul Wurth Umwelttechnik GmbH, the Group’s competence centre for the development of envi-ronmental protection technologies for the metals industry, we design and supply the full range of gas cleaning systems, gas distribution equipment and processes designed to the high-est levels of cleaning effi ciency, safety and reliability as well as providing the best possible environmental protection.
Dry Dust Separation Technology
In the fi eld of dry dust separation, the Paul Wurth solution can be based on the following technologies:
Dustcatcher
Tangential Cyclone
Axial Cyclone
The axial cyclone technology, successfully introduced by Paul Wurth for the dry separation in blast furnace top gas cleaning, shows how operational and economic aspects can be perfectly combined. The high separation effi ciency of up to 90 % helps to minimise the operational cost and to optimise the residue handling downstream of the plants.
Variable design:
With or without inlet isolation valve
Wear lining to guarantee long service life
Dust discharge system
We propose individual and fl exible concepts, which are perfectly adapted to the customer’s environmental, economic and operational requirements:
EPC (Engineering, procurement & construction) contracts, on a turn-key basis
Supply of single equipment items
Revamping concepts for existing plants
Concepts allowing a variable plant layout

Wet Separation Technology
In the fi eld of wet gas cleaning techniques, the Paul Wurth Annular Gap Scrubber is the state-of-the-art technology for blast furnace gas cleaning and top pressure control. It is designed as a two-stage scrubbing unit in one single vessel. A demister installed downstream guarantees a minimal droplet content at the outlet.
Pre-Scrubber stage
Cooling and pre-cleaning of the gas
Variable solution against corrosion and dust deposits
AGE-Scrubber stage
Top pressure control with annular gap elements
Fine cleaning of gas below 5 mg/m3 i.N.

Thanks to the Paul Wurth Gritzko® valve, the dust discharge system offers new advantages:
Very precise control of discharge fl ow rate
Better sealing tightness due to infl atable seals
Less wear and longer life due to hard faced protection
Annular Gap Element
Wear protected surface for long service life
Maintenance-free operation due to improved stuffi ng box design
Droplet separation
External swirl-type vertical or inclined demister
Free droplet content of clean gas below 5 g/m3 i.N.

Primary Converter Dedusting with Paul Wurth Annular Gap Scrubber
Converter dedusting
Annular Gap Element for converter dedusting
Pressure control for converter dedusting
Given the high accuracy of pres-sure control and the effi ciency of gas cleaning, annular gap elements can also be implemented for other tasks, i.e. for primary converter dedusting.
Relying on an excellent knowledge of the process, combined with operational expertise, the energy consumption can be decreased with accurate air factor control and the clean gas dust content at the fl are stack reduced to less than 50 mg/m3 i.N.
The high fl exibility of the equipment design helps to fi t into existing structures in the frame of revamping projects as well as into new plants.

Energy & Cost-saving Technologies
Energy recovery by using top gas recovery tur-bines (TRT) is the most proven technology for blast furnace plants. Integrated solutions can be easily realized and included into the process.
If the blast furnace gas cleaning plant is additionally equipped with bag fi lter technology, the energy output of the TRT is also increased by approx. 15-20 %. Individual solutions for high temperature applications are possible.
Bearing in mind the present and future ecological challenges and further energy and cost-saving re-quirements, our efforts in the fi eld of industrial gas cleaning will focus on combining existing solutions and new technologies. One of our future projects will concentrate on the carbon dioxide (CO2) capture by using scrubber and regeneration technology.
We keep on fi nding the best solution!
For a further increased energy recovery, blast furnace gas preheating can be added. The energy output can be increased by 75 % by using excess gases or exhaust gases from neighbouring plants.
