Industrial Air Pollution Control & VOC Emission Control Technologies
DEC • Dynamic Environmental Corporation engineers, designs and delivers sustainable industrial Air Pollution Control (APC) systems for the recovery, concentration, destruction and treatment of VOC, HAP and other industrial emissions.
DEC evaluates each emission stream from its process conditions and treatment objectives, then selects and proposes the appropriate technologies or integrated systems for the application.
DEC AT A GLANCE
DEC serves industrial processes across flexible packaging, converting, coating, chemical, petrochemical and pharmaceutical industries. Its engineering approach combines accumulated process knowledge with data-driven technology selection and project-specific system design.
Industrial APC Systems for Solvent Laden Air, from 200 m³/h to 1,000,000 m³/h
DEC engineers industrial Air Pollution Control systems for Solvents Laden Air (SLA) capacities from approximately 200 m³/h to 1,000,000 m³/h. This wide capacity range enables DEC to engineer emission-control systems for both relatively small process exhaust streams and very large industrial airflows.
The required APC system configuration is determined from several parameters (project conditions), including the actual Solvents Laden Air stream volume, solvent composition, VOC concentration, temperature, moisture, operating conditions and applicable emission requirements.
Start with the Data: Evaluate, Select and Engineer the Right Process
DEC starts with the collection and analysis of process and emission-stream data. DEC's engineering team reviews the available information, identifies and clarifies missing or uncertain data, and defines the process conditions and treatment requirements for the application.
Applicable emission requirements are established from the customer's environmental permit, where applicable, customer-specific requirements, and the relevant local environmental legislation, regulations, codes and prescribed limits.
DEC's broad portfolio enables alternative process pathways to be evaluated and the most appropriate process or combination of processes to be selected and engineered for the specific application.
Recover
Recover valuable solvents and VOCs where recovery is technically and economically appropriate.
Concentrate
Concentrate dilute VOC streams before downstream treatment or recovery.
Oxidize
Oxidize non-recoverable VOC and HAP emissions through direct, regenerative or catalytic thermal oxidation.
Treat
Apply appropriate scrubbing, filtration and other treatment technologies for additional pollutants.
Recover Energy
Recover usable thermal or process energy where the application permits.
Industrial Air Pollution Control Technologies
DEC provides a portfolio of industrial Air Pollution Control technologies for recovering, concentrating, oxidizing and treating VOCs, HAPs and other industrial emissions. Select a technology family to explore its individual processes.
Which Air Pollution Control Technology Is Appropriate?
The appropriate technology depends on the emission characteristics, treatment objective and operating requirements. DEC can combine technologies when a single treatment step is not sufficient.
| Emission challenge or objective | Typical DEC approach |
|---|---|
| Recover valuable solvent vapours | SRU™ solvent recovery |
| Concentrate dilute VOC emissions | XBC™ VOC concentration |
| Oxidize non-recoverable VOC or HAP emissions | XTO™ thermal oxidation |
| Remove or treat other gaseous pollutants | XSU™ scrubbing |
| Remove particulates, aerosols or other exhaust contaminants | XFU™ filtration |
| Recover usable thermal or process energy | ERS™ energy recovery |
Not Sure Which APC Technology You Need?
Start with the available process and emission-stream data. DEC can review Solvents Laden Air (SLA) volume, solvent composition, VOC concentration, temperature, moisture and operating conditions, clarify missing information and evaluate alternative recovery, concentration, oxidation or treatment pathways to identify the process or integrated solution best suited to the application.
Discuss Your Emission Stream →Integrated Air Pollution Control Systems
Industrial emission streams often require more than one treatment step. DEC integrates recovery, concentration, oxidation, scrubbing, filtration, dehydration and energy-recovery technologies according to the process requirements.
Examples include combinations such as VOC recovery and thermal oxidation, VOC concentration and oxidation, or emission treatment with energy recovery.

A Century of Industrial Technology Heritage
DEC combines more than a century of industrial technology heritage. That accumulated knowledge supports today's process-led approach to industrial Air Pollution Control.
1920s
Activated-carbon technology heritage and early solvent-recovery applications.
1946
DEC roots established in Milan, Italy, as Depurazione Emissioni per l'Industria Chimica.
1966–1988
Evolution as Depurazione Emissioni Convogliate and expansion of industrial emission-control engineering.
1988 → today
Integration of additional activated-carbon and solvent-recovery technology heritage into DEC's engineering portfolio, followed by continued development of industrial APC technologies.
Heritage is not simply a measure of time: it represents accumulated process knowledge, technology development and experience applied to increasingly complex industrial emission streams.
From Heritage to Hybrid Air Pollution Control Engineering
Accumulated Knowledge
DEC's industrial technology heritage provides a foundation of process, adsorption, solvent recovery, oxidation and emission-control engineering knowledge.
Technology Breadth
DEC's portfolio spans solvent recovery, VOC concentration, thermal oxidation, scrubbing, filtration, dehydration and energy recovery.
Process-Led Selection
DEC starts with the process and emission stream, analysing flow, composition, concentration, temperature, moisture, operating conditions and applicable requirements before selecting the treatment pathway.
Hybrid Engineering
When one treatment step is not sufficient, DEC can combine recovery, concentration, oxidation and complementary treatment technologies into an integrated APC system.

Frequently Asked Questions
industrial challenges, DEC solutions
What does DEC do?
DEC engineers and delivers industrial Air Pollution Control systems for VOC, HAP and other industrial emissions, including recovery, concentration, thermal oxidation and complementary treatment technologies.
What is industrial Air Pollution Control?
Industrial Air Pollution Control involves the engineering and application of technologies that recover, reduce, oxidize, remove or otherwise treat pollutants from industrial emission streams before discharge.
How does DEC select an emission-control technology?
DEC collects and analyses process and emission-stream data, identifies and clarifies missing or uncertain information, considers the customer's environmental permit and customer-specific requirements together with relevant local environmental legislation, regulations, codes and prescribed limits, and then evaluates and selects the appropriate technology or integrated system.
Can DEC combine different Air Pollution Control technologies?
Yes. DEC can integrate technologies such as solvent recovery, VOC concentration, thermal oxidation, scrubbing, filtration and energy recovery when a combined treatment strategy is appropriate.
What industries does DEC serve?
DEC serves industrial processes with significant VOC, HAP and other emission-control requirements, including flexible packaging, chemical processing and industrial manufacturing.
What are the stages of a DEC APC project?
DEC's project process runs from process assessment through feasibility analysis, site visit, scope of work definition, APC system engineering, turn-key EPC delivery and system acceptance testing, to ongoing lifetime support.
Does DEC follow EPC or EPCI project delivery standards?
