Industrial Solvent Recovery Systems
Industrial processes that use organic solvents can generate significant solvent vapours and Volatile Organic Compound (VOC) emissions.
Recovering these valuable compounds instead of destroying or releasing them can reduce raw material consumption, lower operating costs, and improve environmental performance.
Delmer Group provides advanced industrial solvent recovery systems designed to capture, separate, and recover solvents from process air and industrial exhaust streams. Our customized solutions help industries reuse valuable solvents while reducing VOC emissions and supporting cleaner, more resource-efficient production.
Each solvent recovery plant is engineered according to the solvent composition, VOC concentration, airflow rate, process temperature and required recovery efficiency.
What Is a Solvent Recovery System?
A solvent recovery system is an industrial air treatment technology used to capture organic solvent vapours from process exhaust gases and recover them for potential reuse or further purification.
Instead of treating solvents only as waste emissions, the recovery process converts VOC-containing exhaust streams into a source of recoverable material.
Depending on the application, solvent recovery may involve adsorption, desorption, condensation, distillation or a combination of treatment technologies.
The recovered solvent can then be collected, purified, and returned to the production process where technically suitable.
Activated Carbon Solvent Recovery Systems
Activated carbon adsorption is a widely used technology for capturing VOCs and solvent vapours from industrial exhaust air.
Activated Carbon Adsorption Technology
Contaminated air passes through specially designed activated carbon beds. Organic compounds are adsorbed onto the carbon surface while treated air is discharged from the system.
Once the carbon reaches a defined saturation level, a controlled regeneration process removes the captured solvents from the adsorption media.
Key benefits include:
- High VOC capture efficiency
- Recovery of valuable solvents
- Regenerable adsorption media
- Continuous industrial operation
- Reduced atmospheric emissions
- Flexible multi-bed system configurations
Multiple adsorption vessels can be integrated to enable continuous treatment while individual beds undergo regeneration.
Solvent Desorption & Regeneration
During the regeneration cycle, captured solvents are removed from the activated carbon using a controlled desorption process.
Regeneration Technologies
Depending on the solvent and process requirements, regeneration technologies may include:
- Steam regeneration
- Inert gas regeneration
- Thermal regeneration
- Vacuum-assisted desorption
The solvent-rich vapour generated during regeneration is transferred to the downstream recovery section for condensation and separation.
Automatic process control ensures safe and efficient switching between adsorption and regeneration cycles.
Condensation-Based Solvent Recovery
Condensation systems recover solvents by cooling VOC-rich gas streams below the condensation temperature of the target compounds.
Condensation Technology
As the gas temperature decreases, solvent vapours change into liquid form and can be collected for reuse or further treatment.
Condensation technology is particularly suitable for:
- High solvent concentrations
- Recoverable organic compounds
- Batch production processes
- Concentrated VOC streams
Advanced cooling and heat exchange technologies can be integrated to improve energy efficiency and solvent recovery performance.
Solvent Separation & Purification
Industrial exhaust streams may contain mixtures of solvents, water, and other process compounds.
Purification Solutions
Delmer Group can integrate separation and purification technologies to improve recovered solvent quality.
Solutions may include:
- Distillation systems
- Phase separation
- Decantation
- Condensate treatment
- Solvent-water separation
- Multi-stage purification
The recovery process is customized according to the physical and chemical characteristics of the solvent mixture.
VOC Recovery vs Thermal Oxidation
Not every VOC stream should be treated using the same technology.
Solvent Recovery
For concentrated exhaust streams containing valuable solvents, solvent recovery can provide significant economic benefits by returning usable materials to the production process.
Thermal Oxidation
For low-value, complex or non-recoverable VOC streams, Regenerative Thermal Oxidizers (RTO) or other oxidation technologies may provide a more suitable treatment solution.
Delmer Group evaluates key process parameters including:
Based on these factors, the most efficient recovery or destruction technology can be selected.
Intelligent Process Control & Safety
Solvent recovery systems operate with combustible and potentially hazardous organic compounds. Reliable automation and process safety are therefore essential.
Safety & Control Systems
Our systems can incorporate:
- PLC-based automatic control
- VOC concentration monitoring
- Temperature and pressure monitoring
- Automatic adsorption cycle control
- Solvent level monitoring
- Explosion protection systems
- Gas detection
- Nitrogen inerting systems
- Safety interlocks and alarms
- Remote monitoring capabilities
Every system is engineered with careful consideration of process safety and applicable industrial standards.
