EMMISSION CONTROL AND STACKS

Overview: Our engineering team specializes in the design, fabrication, and installation of industrial emission stacks for air exhaust, scrubbers, and process ventilation systems.

We deliver custom-engineered stack solutions that ensure environmental compliance, structural reliability, and long-term performance under harsh industrial conditions.

Engineering Expertise: We design stacks to meet international standards such as ASCE 7, EN 1991-1-4, ASME RTP-1, ASTM D3299, and regional regulatory codes.

Our stack designs integrate aerodynamic, structural, and thermal considerations to ensure safe and efficient operation in chemical, petrochemical, salt-processing, and wastewater treatment facilities.

Key Design Parameters:

• Gas flow rates: up to 100,000 m³/h
• Material: FRP, stainless steel, carbon steel, or composite hybrid
• Height: up to 80 m, modular or monolithic construction
• Diameter range: 400 mm to 2,000 mm
• Wind and seismic load design based on ASCE 7-22 / Eurocode EN 1991-1-4
• Thermal and chemical resistance for acidic, saline, and corrosive gases

For corrosive exhaust streams, we offer FRP (Fiberglass-Reinforced Plastic) emission stacks with woven or filament-wound construction, resistant to acid vapors, chloride attack, and high humidity.

Our segmented FRP stacks (typically 6 × 10.5 m segments, Ø 850 mm, 10 mm wall) are connected by flanged joints with gasketed sealing, designed for easy transportation and modular erection.

Advantages:

• Lightweight yet high strength-to-weight ratio
• Corrosion-free operation
• Minimal maintenance requirements
• Compatible with wet scrubbers and bio-filter systems
• Long design life (≥ 25 years)

Structural & Dynamic Analysis:

Each stack undergoes detailed finite element modeling (FEM) to ensure stability under:

• Wind gusts, vortex shedding, and seismic accelerations
• Thermal gradients and support stiffness variations
• Anchor bolt pull-out and foundation overturning checks

We provide full RFEM or STAAD.Pro structural reports including:

• Wind pressure contour maps
• Mode shapes and natural frequency analysis
• Foundation load summaries
• Flange bolt and lug connection design

• Shop fabrication with precise flange alignment and UV-resistant topcoats
• On-site assembly and lifting supervision
• Anchor system and base plate detailing for concrete pedestals
• Optional gas sampling ports, drain connections, and access platforms

• Scrubber exhaust systems (acid gas, amine vapors, H₂S)
• Chemical and fertilizer plants
• Wastewater treatment facilities
• Salt drying and calcination lines
• Power generation and heat-recovery units

All stacks are designed for low noise, minimal pressure loss, and zero visible emissions, ensuring compliance with:

• Royal Commission (RC-Jubail/Yanbu)
• EPA 40 CFR Part 60
• European Industrial Emissions Directive (IED)
