Industrial Air Pollution Control Engineered Around the Emission Stream
DEC • Dynamic Environmental Corporation engineers, designs and delivers industrial Air Pollution Control (APC) systems for Volatile Organic Compounds (VOC), Hazardous Air Pollutants (HAP) and other industrial emissions.
The starting point is the emission stream rather than a preselected equipment package. 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.
Solvent Laden Air Flow Rates: from Compact to Ultra-High Capacity
DEC engineers industrial Air Pollution Control systems for Solvent Laden Air (SLA) flow rates ranging from approximately 200 m³/h to 1,000,000 m³/h. This wide flow-rate 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 Solvent Laden Air flow rate, solvent composition, VOC concentration, temperature, moisture, operating conditions and applicable emission requirements.
Performance Defined by the Abatement Objective
DEC designs industrial Air Pollution Control and solvent-recovery systems around measurable abatement objectives. Depending on the emission stream and process requirements, performance may be defined by the destruction of non-recoverable VOCs or the removal of VOC mass from process air, while solvent-recovery applications add the objective of recovering valuable solvents for reuse.
RRE & DRE
RRE • Recovery and Removal Efficiency
RRE quantifies the percentage of pollutant mass removed and recovered across an industrial VOC recovery system.
DRE • Destruction and Removal Efficiency
DRE quantifies the percentage of pollutant mass removed or destroyed across an industrial oxidizer.
DEC.SRU™ Solvent Recovery and DEC.XTO™ thermal oxidation systems are engineered around the required abatement performance, process conditions and applicable environmental requirements. Actual Air Pollution Control (APC) performance depends on the selected technology, solvent or pollutant characteristics, inlet concentration, airflow, moisture, operating conditions, measurement methodology and applicable environmental permit 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 DEC.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 DEC.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 DEC.ERS™ portfolio includes UltraLoop, waste heat recovery and waste-to-energy pathways.

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 | DEC.SRU™ solvent recovery |
| Concentrate dilute VOC emissions | DEC.XBC™ VOC concentration |
| Oxidize non-recoverable VOC or HAP emissions | DEC.XTO™ thermal oxidation |
| Remove or treat other gaseous pollutants | DEC.XSU™ scrubbing |

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 are RRE and DRE in industrial emission control?
RRE (Recovery and Removal Efficiency) describes the percentage of pollutant mass removed and recovered across a solvent recovery system, while DRE (Destruction and Removal Efficiency) describes the percentage of pollutant mass removed or destroyed across an industrial oxidizer. DEC uses the appropriate performance metric according to the treatment objective: solvent recovery focuses on recovering valuable VOCs, while thermal oxidation focuses on destroying non-recoverable VOCs and other applicable pollutants.
How can solvent recovery improve the Triple Bottom Line (TBL)?
Where the process and solvent stream are suitable for recovery, an DEC.SRU™ can recover valuable solvents from process emissions instead of losing them with the exhaust. This can create economic value through solvent recovery and reuse, environmental value through reduced solvent losses and VOC releases, and operational value through an engineered recovery system integrated with the process. These three dimensions form the Triple Bottom Line (TBL) perspective.
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.
