Chemical scrubber ductwork integration

Chemical Scrubber Ductwork Integration by EKG M&E Sdn Bhd

In the industrial sectors of Kuala Lumpur, Selangor, and Nilai, a chemical scrubber is only as effective as the ductwork that feeds it. Chemical Scrubber Ductwork Integration requires precise engineering to ensure that 100% of hazardous fumes are captured and transported to the treatment unit without leakage, condensation pooling, or structural degradation.

EKG M&E Sdn Bhd specializes in the seamless integration of PVC, PP, and FRP ducting with wet scrubbers and carbon adsorbers, ensuring your facility meets DOE (Department of Environment) emission standards and DOSH safety mandates.

The Engineering of a "Closed-Loop" Integration

Successful integration ensures the exhaust stream remains contained and the scrubber operates at peak efficiency.

1. Airtight Transition Modules (ATC 6)

The connection between the ducting and the scrubber inlet is a frequent point of failure.

• Flanged & Laminated Joints: We utilize heavy-duty, chemically resistant flanges with EPDM or Viton gaskets. For high-pressure FRP systems, we use hand-layup lamination to create a monolithic, leak-proof bond between the duct and the scrubber body.

• Airtightness Class 6: All integration points are pressure-tested to ensure zero bypass air, which would otherwise dilute the chemical concentration and reduce the scrubber's removal efficiency.

2. Condensate & Leachate Management

Chemical fumes often condense back into liquid form inside the ducting before reaching the scrubber.

• Pitched Duct Runs: We install ducting with a minimum 1:50 pitch back toward the scrubber or toward dedicated PVC/FRP Drain Points.

• Integrated Mist Eliminators: At the duct-to-scrubber interface, we integrate mist eliminators to prevent liquid droplets from being carried over into the exhaust fan, protecting the impeller from chemical erosion.

3. Strategic Fan Placement (Pull vs. Push)

• Induced Draft (Pull) Configuration: EKG typically integrates the exhaust fan downstream of the scrubber. This keeps the entire ductwork run under Negative Pressure, ensuring that any accidental breach in the duct pulls air in rather than pushing toxic fumes out into the factory.

Critical Operational & Energy Benefits

As a specialized M&E contractor, EKG ensures your integrated system supports both compliance and the EECA 2024 energy mandates:

• TNB Energy Efficiency (System Curve Matching):

  We calibrate the ductwork diameter and scrubber internal resistance to match the fan's peak efficiency curve. Using Variable Frequency Drives (VFDs), we modulate the fan speed based on the scrubber's differential pressure, directly reducing your monthly TNB electricity bill.

• DOE Stack Monitoring Compliance:

  Our integration includes the installation of Isokinetic Sampling Ports and access platforms in accordance with DOE MS 1596 standards, facilitating easy annual stack testing.

• Vibration Isolation:

  To prevent the transmission of fan harmonics to the scrubber housing (which can cause structural cracks over time), we utilize chemical-grade flexible connectors made of reinforced PVC or PTFE.
