MEROS® – Maximized emission reduction of sintering and pelletizing
MEROS is a waste-water-free process for removing pollutant concentrations such as dust and harmful metallic and organic components from the sinter offgas. Through a series of treatment steps, the technology achieves levels previously unattained with conventional gas-treatment techniques.
SCR DeNOx Plants for reducing NOx
Primetals Technologies offers highly efficient selective catalytic reaction (SCR) solutions for maximum reduction of nitrogen oxides (NOx) emissions for both new and existing sinter gas cleaning applications.
Room and secondary dedusting for sinter and pelletizing plants
Aside from primary offgas treatment, it is also essential to have ambient conditions in a sinter plant that ensure a safe working environment. The proper design and location of hoods is essential to achieve the highest dust collection. CFD calculations help to design optimized dust capture and flow distribution in the hoods.

MERIM® - Maximized emission reduction and energy recovery
Primetals Technologies has developed advanced dry top gas cleaning technology for blast furnaces, COREX and FINEX, with considerable benefits for the environment and customers compared to the conventional wet top gas cleaning system. The cleaned gas meets both current and future emission regulations, and the CO2 footprint can be significantly reduced.
Wet dedusting system for blast furnaces – Meeting environmental standards with highly efficient gas cleaning
As a state-of-the-art system integrator for blast furnace dedusting equipment, Primetals Technologies offers comprehensive in-house solutions for primary and secondary offgas treatment.
Casthouse and stockhouse dedusting for blast furnaces
For the offgas treatment, the exhaust system collects dust laden air from the widely distributed off-take points. An important factor in the dedusting logistics is optimum dimensioning of the ductwork and the damper system to compensate pressure losses and thus reduce fan power requirements. To optimize the arrangement, advanced CFD calculations are carried out to support the design calculations.

Zeron® – The Future of Pulse Jet Filters
Primetals Technologies entered an exclusive cooperation with Kappa Filter Systems
(Steyr, Austria) who developed the internationally patented Zeron
large fabric filter system. The solid concrete panel structure allows
all the functional areas to be integrated compactly into one filter
building for the first time – from the dust pre-separation to the clean
