Flue gas treatment
Studybel’s flue gas treatment operations are conducted under the banner of Leroux & Lotz Technologies, a sister company of the Boccard Group and a specialist in energy and combustion technologies, enabling the design and implementation of comprehensive systems (Air Quality System – AQS) that ensure environmental compliance and the operational reliability of industrial facilities.
As an EPC contractor, the company is involved in every stage of a project’s lifecycle—from performance specification to commissioning—whether for new facilities, complex retrofits, or upgrades—while managing critical interfaces ranging from reagent management to waste treatment, and integrating process, mechanical, regulatory, and operational constraints.
Our Air Quality System (AQS) solutions
1. Dust Removal
Studybel designs custom dust collection systems (multicyclones, electrostatic precipitators, bag filters, or hybrid solutions) that ensure very low emission levels—as low as 5 mg/Nm³—while meeting the most stringent operational constraints and regulatory requirements.
2. Flue gas treatment (FGT)
Studybel deploys dry and semi-wet neutralization systems recognized for their efficiency, flexibility, and operational reliability, incorporating the use of reagents (bicarbonate, lime, activated carbon) and residues—from storage through disposal—to ensure efficient and flexible filtration.
3. Denitrification (DeNOx)
Reduction of nitrogen oxides (NOx) using SNCR (Selective Non-Catalytic Reduction) or SCR (Selective Catalytic Reduction), with a comprehensive approach that takes into account the temperature range, process constraints, boiler interfaces, and long-term operational requirements.
An integrated EPC approach throughout the entire lifecycle
Under the Leroux & Lotz Technologies banner, Studybel provides services throughout the entire lifecycle of flue gas treatment systems:
- New construction: complete design and installation of AQS systems, integrated with the furnaces and boilers.
- Retrofit & upgrade: regulatory compliance, adaptation to new fuels, and improved environmental performance.
- Services & expertise: troubleshooting, OPEX optimization, improved availability, and ongoing technical support.
These solutions are designed specifically for the waste-to-energy, biomass, minerals, steel, refining, cement, and paper industries.
