Achieve 99.9% Destruction Efficiency
and Global Compliance with Gelan's
Engineered Solutions
Gelan engineers industrial combustion systems and emission control systems designed for the most
demanding petrochemical, refining, and chemical processing environments. As global regulations tighten,
simply "burning off" waste is no longer enough. You need precise petrochemical emission control strategies
that handle complex gas streams safely.
Our equipment—ranging from Direct Fired Thermal Oxidizers (DFTO) to Waste Gas Incinerators—delivers high-
temperature destruction of hazardous pollutants (VOCs, HAPs) while maintaining strict compliance with global
environmental standards. Unlike standard equipment suppliers, Gelan focuses on the entire thermal process:
ensuring flame stability, optimizing residence time, and recovering waste heat to lower your plant's OPEX.
| Comparison Item | Gelan Solution | Industry Challenge |
|---|---|---|
| Waste Gas Stability | CFD-based combustion modeling with corrosion-resistant materials (e.g., Inconel, Hastelloy) to maintain stable destruction, even at low load | Petrochemical off-gases fluctuate in BTU content and may contain corrosive components such as H₂S or chlorides |
| NOx & CO Control | Staged air combustion and low-NOx burner technology to suppress thermal NOx formation at the source, often avoiding SCR systems | Increasingly strict NOx and CO emission limits imposed by environmental authorities |
| Fuel Consumption | Integrated waste heat recovery (waste heat boilers or air preheaters) converting exhaust energy into steam or hot air to offset fuel use | Incinerators require high auxiliary fuel input, resulting in elevated operating costs |
We provide waste management in petrochemical industry solutions, specifically combustion-based systems for ethylene plants, aromatics units, butadiene production, and polymer off-gas streams.
Designed for voc waste gas treatment systems handling solvents, ketones, alcohols, acid gases, and mixed industrial VOC streams.
Suitable for blowdown gas, flare-header relief, sulfur-related off-gas, and hydrocarbon vapor disposal. Our systems act as critical exhaust gas treatment units to prevent flaring violations.
We engineer systems based on:
● Gas composition & calorific variability
● Corrosive species (H₂S, SOx, Cl-compounds)
● Stability limits during low-load conditions
This prevents flame instability and backfire risks—common pain points for procurement and engineering teams looking for reliable combustion systems manufacturers.
Our solutions combine burner optimization, combustion air management, and NOx-reduction pathways.
● Result: Higher destruction efficiency, lower NOx, and more stable combustion across varying loads.
Materials and designs tailored for high-temperature oxidation zones and acidic flue gas.
● Adaptability: Available options include CS, SS, Duplex, and high-nickel alloys depending on corrosivity and temperature.
Our emission control devices and vessels are built to:
● ASME U / U2 Stamps
● API and refinery emission guidelines
● PED / EAC / SELO requirements
Ensures smooth acceptance by EPCs, owners, and regulators in the US, Russia, and SE Asia.
Gelan can integrate emission control with firebox convection sections, Waste Heat Boilers, and Economizers. We help plants recover heat and reduce total OPEX—we don't just "treat waste," we optimize your entire energy loop.
They safely destroy VOCs, hydrocarbons, and hazardous gases through engineered combustion—helping plants meet emission limits while maintaining safe operation.
They handle off-gas from cracking furnaces, reformers, reactors, storage tanks, and other units where flaring is insufficient or non-compliant.
It depends on your gas composition, heating value, flow rate, corrosive components, and emission targets.
Share your off-gas data—Gelan will perform a destruction/combustion assessment.
This is the most common concern. Gelan integrates waste heat recovery modules (Waste Heat Boilers or Air Preheaters) into our industrial combustion systems. Instead of wasting heat, we capture it to generate steam or preheat incoming air, often reducing auxiliary fuel consumption by 40–60%.
Yes. Process upsets are normal. Our units feature a high-turndown burner and a sophisticated combustion control system (BMS) that automatically adjusts the air/fuel ratio. This ensures 99.9% destruction efficiency and flame stability even when your waste gas flow fluctuates significantly (low-load conditions).
Absolutely. Unlike standard emission control devices that only handle gas, Gelan designs multi-lance industrial combustion burner systems. We can inject waste gas, aqueous waste, and organic liquids into the same chamber simultaneously, simplifying your plant's waste management infrastructure.
Yes. We frequently retrofit units to improve NOx levels, stabilize combustion, or recover waste heat.
Yes. For hazardous pollutants (HAPs) or strict petrochemical emission control zones, we design systems with higher operating temperatures (>1100°C) and longer residence times (>1.5s). We also offer performance guarantees and NOx reduction system technologies to ensure you pass third-party environmental performance tests (Source Testing).
To minimize site work, Gelan functions as a "Plug-and-Play" combustion systems manufacturer. We maximize shop fabrication, delivering units as skid-mounted modules with pre-wired instrumentation and piping. This significantly reduces installation time and risk at your facility.environmental performance tests (Source Testing).
