Industrial Air Pollution Control Engineered Around the Emission Stream
DEC • Dynamic Environmental Corporation engineers, designs and delivers industrial Air Pollution Control (APC) systems for VOC, HAP and other industrial emissions.
The starting point is the emission stream—not a preselected machine. DEC evaluates process conditions, treatment objectives and applicable requirements, then selects and engineers the appropriate technology or integrated system.
DEC AT A GLANCE
DEC serves industrial processes across established industrial markets, including flexible packaging, converting, coating, chemical, petrochemical and pharmaceutical applications. The industry provides the process context; the actual emission stream determines the treatment architecture.
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.
From Industrial Market to Emission-Control Architecture
DEC applies the same emission-stream engineering approach across different industrial markets. The industry and process define the operating context; DEC then evaluates the actual emission stream, treatment objective and constraints to determine whether to recover, concentrate, oxidize, treat or recover energy.
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.
One Emission Stream Does Not Always Need One Technology
DEC's distinctive approach is to engineer the treatment pathway around the stream itself. When recovery, concentration, oxidation or complementary treatment solve different parts of the problem, DEC can combine them into one coordinated APC system.
Recover what has value
Where solvent recovery is technically and economically appropriate, DEC can capture VOCs for reuse rather than treating them only as waste.
Explore SRU™ solvent recovery →Concentrate what is dilute
For dilute VOC streams, concentration can reduce downstream air volume and create a more suitable stream for recovery or oxidation.
Explore XBC™ concentration →Oxidize what is not recoverable
Non-recoverable VOC and HAP loads can be routed to direct, regenerative or catalytic thermal oxidation according to the application.
Explore XTO™ thermal oxidation →Recover energy where it matters
Energy recovery can be integrated where process conditions allow useful thermal or process energy to be recovered; DEC's ERS™ portfolio includes UltraLoop, waste heat recovery and waste-to-energy pathways.

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 |
Bring the Data You Have. DEC Will Define What Is Missing.
For an initial technical discussion, useful inputs can include Solvent Laden Air (SLA) flow, solvent composition, VOC concentration, temperature, moisture, operating pattern and applicable emission requirements. DEC can clarify missing information and compare alternative treatment pathways.

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.
