Gas turbine generator exhaust treatment | Empowering green and efficient energy operation

Driven by the dual forces of energy transition and environmental regulations, gas turbine generators have emerged as the “powerhouse” for critical facilities like energy stations, industrial parks, and data centers, thanks to their efficiency and clean operation. However, these systems generate substantial emissions containing NOx , CO , and trace VOCs . The high-temperature operation and fluctuating loads pose significant purification challenges. Guangdong Green Valley Environmental Protection, specializing in industrial exhaust treatment, has developed a “customized and highly adaptable” solution tailored to gas turbine generators’ unique operational demands. By leveraging advanced technologies, this approach effectively addresses emission compliance issues while achieving a dual balance between power generation efficiency and environmental standards.

Unlike traditional diesel generators, gas turbine generator exhaust treatment faces unique challenges. High-temperature environments accelerate catalyst deactivation, frequent load fluctuations compromise treatment efficiency, and space-constrained equipment layouts limit installation flexibilityall factors undermining conventional exhaust purification systems. Through continuous technological innovation and scenario-specific solutions, Green Valley Environmental Protection has developed an integrated system featuring a high-efficiency SCR denitrification system paired with high-temperature DOC oxidation catalysts, precisely addressing these industry-wide bottlenecks.

High temperature adaptation SCR system: solve the core problem of NOx treatment

Gas turbine exhaust contains NOx with emission concentrations ranging from 500-1500 mg/m³N at high temperatures, where traditional SCR catalysts often suffer from high-temperature sintering and activity degradation. Green Valley Environmental Protection’s high-temperature SCR denitrification system for gas turbines delivers three core advantages: 1) Wide-temperature-range efficiency: The innovative catalyst maintains over 95% denitrification efficiency during both full-load (high-temperature) and low-load (cooling) transitions, reducing NOx emissions below 50 mg/m³N to meet China VI and stricter regional environmental standards; 2) Enhanced durability: The catalyst support uses high-strength honeycomb ceramic material with excellent thermal shock resistance, effectively extending service life; 3) Precision ammonia injection control: Real-time monitoring of load, rotational speed, and exhaust flow data dynamically adjusts urea injection volume, balancing operational efficiency with economic performance.

High temperature DOC oxidation system: simultaneous removal of CO and VOCs

During initial startup or low-load operation of gas turbines, exhaust gases may exhibit elevated CO concentrations reaching 1000 mg/m³N with trace VOCs . Direct passage through SCR denitrification systems could lead to catalyst deactivation. Green Valley Environmental Protection employs a high-temperature DOC oxidation system as a pre-treatment unit, effectively oxidizing CO into harmless COwith over 98% removal efficiency. This process simultaneously converts VOCs into COand HO , minimizing catalyst damage. Crucially, the DOC system oxidizes NO in exhaust gases while converting it into NO. The resulting NOcan significantly accelerate the reduction of NHand NOx within the SCR system, enhancing denitrification efficiency by 10%-15% and achieving synergistic improvements in overall SCR performance.
