If left untreated these have the potential to devastate local ecosystems and threaten the health of the local population. Safely treating the variable demands of high strength wastewater requires system flexibility, controlling the levels of dissolved oxygen (DO) to ensure the biological process is operating at peak efficiency. Fuel Tech’s portfolio of technologies can enhance operational efficiencies while optimizing wastewater treatment, and ensuring effective emissions control.
CHEMICAL & PETROCHEMICAL
Reducing air emissions and minimizing the cost of treating wastewater
Chemical and petrochemical processing generates wastewater high in complex biological oxygen demand (BOD) and chemical oxygen demand (COD) pollutants.
DGI® Dissolved Gas Infusion
DGI combines best-on-the-market oxygen transfer efficiency with precision accuracy, to deliver an energy-efficient and cost-effective solution for use in water and wastewater treatment systems. This cutting-edge technology achieves rates of 99+% gas transfer by pre-dissolving high purity gas in a separate pressurized slipstream using a plunging jet saturator. The slipstream can reach up to 900mg/l oxygen concentration; it is then added to the main volume of water and diluted to meet precise specifications.
Benefits:
- Effective, flexible and environmentally friendly
- DGI combines a patented infusion vessel and patent-pending injector array to ensure effective dissolved oxygen (DO) delivery
- Highest oxygen transfer efficiency available on the market
Selective Non-Catalytic NOx Reduction (SNCR) Technology
Our NOxOUT® SNCR technology is designed to cost-effectively reduce nitrogen oxides (NOx) from stationary combustion sources. This intelligent, in-furnace technology uses multiple levels of injection of stabilized urea liquor into the optimal temperature zones inside a furnace or boiler, to optimize the reduction of nitrogen oxides. SNCR can be used by utilities firing coal, oil or natural gas, and by waste-to-energy and biomass applications.
Performance
- 25 – 50% NOx Reduction
- NOx outlet emissions of 0.10lb/MMBtu or below
Features:
- Injection of aqueous urea or aqueous ammonia
- Multiple nozzle lances for large furnace applications
- Combined injection strategy to control ammonia slip
Selective Catalytic Reduction (SCR) Technology
SCR is a post-flue gas treatment technology designed to dramatically reduce nitrogen oxide (NOx) emissions from a wide variety of boiler types. Fuel Tech combines extensive design experience with a real-life understanding of plant operations, to maximize performance and minimize the impact on energy production. SCR is used on coal, biomass, oil, natural and waste gases, municipal and hazardous waste.
Benefits:
- Guaranteed NOx reduction performance
- Proven expertise to optimize existing SCR systems using flow modeling, flow control devices and ammonia injection grid modifications
- Dramatically improving efficiency using CFD modeling
ULTRA® Urea Thermal Decomposition Technology
The ULTRA process safely generates high-quality, diluted ammonia for SCR systems and flue gas conditioning applications, by thermally decomposing urea. This ensures a safe, reliable source of ammonia that can be instantly generated onsite when needed. ULTRA can utilize electric heaters, natural gas burners, external flue gas heat exchangers, or the direct use of flue gas as the heat source.
Benefits:
- Capacity of 1.0 to 1,300lbs per hour of ammonia supply
- ULTRA can utilize urea solution concentrations of 32% to 55% by weight and varying levels of urea quality
- Eliminates the risks associated with the transport of storage of hazardous ammonia
- Experience on over 350 applications worldwide
