Odor and VOC Emission Control System
Using an RTO Unit at a Paint Manufacturing Plant

Existing Conditions

The facility contained dozens of process vessels used for paint production involving volatile solvents (VOC). Most of these were not connected to an adequate extraction or treatment system, resulting in non-compliance with regulatory air quality standards.

Challenge

• Lack of technical data – defining emission and airflow rates for each source
• Designing a complex extraction system including dozens of emission points
• Selecting a cost-effective RTO system meeting regulatory and budgetary constraints

Solution

A.B.P. Chemical Engineering and Ventilation Ltd. first conducted a detailed review of all emission sources requiring extraction and treatment.
A series of field measurements were then performed to determine flow rates, VOC, and TOC concentrations under different production scenarios to accurately define emission parameters at each point.

After defining emission characteristics, the next stage involved designing a full extraction network, including ducts, blowers, and control dampers.
In parallel, a suitable treatment system was selected. Following evaluation of available technologies, the most efficient techno-economic solution was determined to be a Regenerative Thermal Oxidizer (RTO) with a capacity of 50,000 m³/h.

To meet the client’s budgetary needs, A.B.P. Chemical Engineering and Ventilation Ltd. sourced a pre-owned RTO system matching the project requirements. The system was purchased, refurbished, installed, and successfully commissioned at the client’s facility.

Beyond engineering design and equipment supply, A.B.P. Chemical Engineering and Ventilation Ltd. also managed all regulatory aspects of the project, including preparation and submission of the building permit application.

Project Scope and Deliverables

• Process and mechanical design defining hoods, airflow rates, and equipment
• Complete extraction network: hoods, intake grilles, ducts, blowers, stacks
• Self-cleaning dust filters
• Activated carbon filters
• Air curtains for building openings
• Continuous emission monitoring systems for stacks
• RTO unit
• LEL, TOC, and analyzer room instrumentation

Sustainability Outcomes

• Significant reduction of odor emissions from building openings
• Elimination of odor nuisances from treatment system stacks

Results

Following comprehensive design and successful project execution, all organic emissions – both point and fugitive – are now captured and treated in full compliance with Ministry of Environmental Protection standards.
The plant operates fully in line with its emission permit, and the system was designed with flexibility for future expansion and process modifications.
