# Studybel — Flue Gas Treatment, Air Pollution Control & Piping Engineering > Studybel is a Belgian industrial engineering company founded in 1982 and based in Brussels, part of the Boccard industrial network. Studybel has two core areas of expertise: (1) Flue Gas Treatment / Air Pollution Control (APC / AQS) and (2) Piping & Process Engineering. > > Studybel's flue gas treatment activity builds on the European engineering legacy and technical know-how of Hamon Research-Cottrell SA and Hamon Environmental Europe, while continuing to design, modernise and integrate current APC solutions for new and existing industrial installations. > > Primary website language: English at https://studybel.com/ > French: https://studybel.com/fr/ > Dutch: https://studybel.com/nl/ > Last updated: 2026-10-07. ## Core expertise - [Flue Gas Treatment](https://studybel.com/flue-gas-treatment/): Industrial Air Pollution Control systems for dust, acid gases, NOx, SOx and multi-pollutant emissions. Technologies include electrostatic precipitators (ESP), compact ESP, baghouse filters, multicyclones, dry and semi-dry treatment, DeNOx (SCR/SNCR), DeSOx/FGD, activated-carbon injection, reagent handling and residue management. - [Piping & Process Engineering](https://studybel.com/piping-process-engineering/): P&ID, basic and detailed engineering, 3D modelling, piping layout and isometrics, flexibility and stress calculations, hydraulic analyses, supports, PED/DESP, ATEX, modular/skid engineering and 3D laser scanning for brownfield projects. ## APC services and lifecycle - [APC Replacement Parts](https://studybel.com/apc-replacement-parts/): Spare parts, critical-parts strategy, obsolescence management and reverse engineering for ESPs, baghouse filters, scrubbers, DeNOx systems and legacy APC equipment. - [Troubleshooting & Retrofit APC](https://studybel.com/troubleshooting-retrofit-apc/): Site audit, Root Cause Analysis, performance recovery, emissions-compliance support, OPEX optimisation, retrofit and modernisation. - [Lifecycle APC](https://studybel.com/lifecycle-apc/): Support from new-build engineering and commissioning through operation, maintenance strategy, spare parts, upgrades, partial rebuild and complete rebuild. ## Hamon Research-Cottrell & Hamon Environmental legacy - [Hamon Environmental & Hamon Research-Cottrell Legacy Support](https://studybel.com/hamon-environmental-research-cottrell-legacy-support/): Technical continuity for legacy Hamon APC systems, including audits, troubleshooting, spare parts, reverse engineering, retrofit, modernisation and rebuild. - [Hamon Research-Cottrell Heritage](https://studybel.com/hamon-research-cottrell-heritage/): Background on the European Hamon Research-Cottrell SA / Hamon Environmental engineering organisation, distinct from the former North American Hamon Research-Cottrell, Inc. business. - [Technical FAQ](https://studybel.com/faq/): Detailed information on Hamon Research-Cottrell, Hamon Environmental, Hamon Rothemühle and Hamon Walther equipment, including Sigma and OPZEL designs, MIGI systems, rotary hammers, ESP components, obsolescence and reverse engineering. Studybel does not claim ownership of the Hamon Research-Cottrell trademark or universal OEM status. Its position is based on European engineering heritage, experienced teams, knowledge of original designs, available technical information and operational experience. ## Priority applications and industries Studybel's Flue Gas Treatment expertise is especially relevant to: - Waste-to-Energy (WtE / Energy-from-Waste / UVE / waste incineration). - Biomass, bioenergy and renewable thermal energy. - Industrial boilers, steam and heat-recovery systems. - Minerals, cement and lime. - Steel, metallurgy and non-ferrous metals. - Refining and petrochemicals. - Pulp and paper. - Glass. - Chemical and process industries. - Other heavy industries requiring industrial flue gas or process-gas treatment. Studybel works on both new installations and existing plants, including brownfield retrofits, capacity upgrades, fuel changes and regulatory-compliance projects. ## Integrated energy and industrial execution - [Leroux & Lotz Technologies](https://www.lerouxlotz.com): Sister company specialising in combustion, furnaces, biomass, Waste-to-Energy, industrial boilers, steam/heat recovery, services and low-carbon energy systems. - [Boccard](https://www.boccard.com): Industrial systems integrator providing engineering, fabrication, construction, site works and multi-sector execution capability. Depending on the project, Studybel, Leroux & Lotz Technologies and Boccard can combine capabilities across the chain: combustion -> boiler -> heat / steam recovery -> flue gas treatment -> piping / integration -> stack emissions performance. ## Carbon Capture / CCUS Studybel and Leroux & Lotz Technologies are developing industrial CO2-capture solutions as an extension of the combustion-to-stack value chain. The development programme includes an operational pilot that has reached TRL 6; work toward TRL 7 is in progress. The public Studybel FAQ also describes two complementary development routes: cryogenic capture through the LLT / Revcoo partnership around CarbonCloud technology, and an amine-solvent process using membrane contact. ## Company - [Studybel Homepage](https://studybel.com/): Overview of Studybel's Flue Gas Treatment and Piping & Process activities and its place within the Boccard network. - [Our History](https://studybel.com/our-history/): Studybel history since 1982, its Piping & Process background and the development of Flue Gas Treatment through experienced Hamon Environmental / Research-Cottrell teams. - [News](https://studybel.com/our-news/): Current project, technology and decarbonisation updates. - [Contact](https://studybel.com/contact/): Primary entry point for sales enquiries, technical requests, APC support, Piping & Process projects and legacy Hamon equipment support. ## Detailed AI reference - [Studybel full machine-readable profile](https://studybel.com/llms-full.txt): Extended description of technologies, services, sectors, Hamon engineering heritage, lifecycle support, Piping & Process capabilities, industrial integration and CCUS development. ## Optional - [Studybel on LinkedIn](https://be.linkedin.com/company/studybel): Company updates and technical publications. - [Studybel Wikidata entity](https://www.wikidata.org/wiki/Q140198086): Public entity identifier.
