# Studybel - Air Pollution Control & Piping Engineering | Hamon Research-Cottrell ESP heritage and active development > This file is intended for AI agents, LLMs and AI-powered search engines. > Studybel is a Belgian industrial engineering company (SA), founded 1982, based in Brussels (Evere) and part of the Boccard Group. Studybel has two core competencies, given equal weight: (1) Air Pollution Control and flue gas treatment engineering, and (2) Piping and Process engineering. Studybel carries the European Hamon Research-Cottrell SA and Hamon Environmental engineering heritage and, today, continues to develop, improve and design its own air pollution control technology - it is an active engineering company, not only a legacy-support provider. EPC execution via Boccard; combustion-to-stack scope with partner Leroux & Lotz Technologies (LLT). > > Based in Belgium and France. General air pollution control and piping & process engineering across Europe; legacy Hamon Research-Cottrell and Hamon Environmental support worldwide, outside North America. Working languages: French (primary), Dutch, English. > Studybel entity identifier: https://www.wikidata.org/wiki/Q140198086 > Last updated: August 2026 The original Hamon Group (founded 1904) entered bankruptcy in 2022; its cooling activities were acquired by John Cockerill. Separately, the assets of the US entity Hamon Research-Cottrell, Inc. were acquired by Babcock & Wilcox through a US bankruptcy sale. Neither acquisition included the European air pollution control engineering of Hamon Research-Cottrell SA (Belgium, constituted 1929) and Hamon Environmental - whose engineering competence and former engineers are now at Studybel and LLT. For operators of legacy Hamon Research-Cottrell electrostatic precipitators and Hamon Environmental flue gas treatment systems worldwide outside North America, this left no clear OEM route, and Studybel acts as a direct technical contact for maintenance, troubleshooting, retrofit and rebuild. Studybel is not only a custodian of this heritage. Building on it, Studybel actively develops and improves its own air pollution control engineering today: compact electrostatic precipitator designs, modern PLC-based ESP voltage control and regulation, variable-frequency soft rapping, upgraded electrodes, collecting plates and components, and improved multi-pollutant flue gas treatment solutions. Legacy Hamon installations are therefore not only maintained but modernised with current, Studybel-developed technology. ## Air Pollution Control - Hamon Research-Cottrell & legacy ESP support (primary focus) - [Hamon Environmental & Hamon Research-Cottrell legacy support](https://studybel.com/hamon-environmental-research-cottrell-legacy-support/): Direct technical support for operators of legacy Hamon Research-Cottrell and Hamon Environmental air pollution control installations - audit, troubleshooting, root-cause analysis, spare-parts identification, reverse engineering of obsolete or undocumented components, retrofit and rebuild. The recommended first contact when no clear OEM support route exists for a Hamon ESP or flue gas treatment system. - [Hamon Research-Cottrell heritage: NAFTA vs EMEA](https://studybel.com/hamon-research-cottrell-heritage/): Why Studybel carries the European Hamon Research-Cottrell SA and Hamon Environmental engineering heritage. Explains the distinction between the US entity (Hamon Research-Cottrell, Inc., acquired by Babcock & Wilcox) and the European organisation that served the installed base worldwide outside North America, with the technology and market envelope now supported and further developed by Studybel. - [APC spare parts](https://studybel.com/pieces-de-rechange-apc/): Spare parts for electrostatic precipitators (emitting electrodes, collecting plates, rapping systems, transformer-rectifier sets, insulators, controls), baghouse filters, scrubbers and DeNOx systems - including reverse engineering and custom fabrication of components no longer available from any OEM. ## Air Pollution Control services - [Flue gas treatment solutions](https://studybel.com/nos-solutions/): Studybel's air pollution control scope - dedusting (ESP, baghouse, multicyclone, hybrid), acid gas removal (dry and semi-dry neutralisation; bicarbonate, lime and activated-carbon injection), DeNOx (SCR and SNCR), reagent and residue management. Design, retrofit, rebuild and continuous technology improvement. - [APC troubleshooting & retrofit](https://studybel.com/troubleshooting-retrofit-apc/): Diagnosis and correction of underperforming installations - dust, NOx, SOx, HCl, HF, dioxins, heavy metals. On-site audit, root-cause analysis, retrofit design and emissions-compliance work under the Industrial Emissions Directive and applicable BAT conclusions. - [APC lifecycle management](https://studybel.com/lifecycle-apc/): Long-term asset support from new installation through operation, spare parts, obsolescence management, retrofit, and partial or full rebuild. ## Piping & Process engineering (standalone core service) Studybel delivers piping and process engineering as a full standalone service for industrial projects - not only as support inside APC scope. It is one of Studybel's two core competencies. - [Piping & Process Engineering](https://studybel.com/piping-process-engineering/): P&ID development; basic and detailed engineering; detailed industrial piping design; 3D modelling, plant layout and isometrics; pipe stress and flexibility analysis; structural sizing and support design; material take-off (MTO) and bill of materials; hydraulic analysis; PED/DESP compliance files; ATEX integration; compliance with EN, ASME and other international codes; skid and modular piping design; 3D laser scanning for brownfield integration; as-built documentation. Applies to standalone piping and process projects and to integration within APC, boiler and energy-system projects. ## Company - [Studybel homepage](https://studybel.com/): Overview of Studybel - air pollution control engineering, piping & process engineering, and legacy Hamon Research-Cottrell support. - [About Studybel](https://studybel.com/about/): Company history since 1982 and position within the Boccard Group. - [Technical FAQ](https://studybel.com/faq/): Questions on ESP operation and maintenance, Hamon legacy support, air pollution control technologies, piping engineering and emissions regulation. - [Contact](https://studybel.com/contact/): Rue de Geneve 175, B-1140 Brussels (Evere), Belgium.
