Diesel Exhaust Fluid Market Trends

Key Emerging Trends in the Diesel Exhaust Fluid Market

The hybrid selective non-catalytic reduction (SNCR) system stands as a groundbreaking technology aimed at enhancing nitrogen oxide (NOx) reduction in flue gas. Operated with a space velocity of SV=6000 hr (-1), this innovative hybrid system employs a two-stage approach—selective non-catalytic reduction (SNCR) followed by selective catalytic reduction (SCR)—to effectively lower NOx levels. The primary goal of this system is to strike a delicate balance between efficiency and cost considerations. With an efficiency range spanning from 60% to 90%, the hybrid SNCR system achieves a harmonious equilibrium between operating costs (OPEX) and investment costs (CAPEX). Notably, this technology demonstrates superior effectiveness at low temperatures, operating optimally below 200°C.

The hybrid SNCR technology represents a strategic fusion of SNCR and SCR, addressing specific cost challenges associated with each. While SCR demands a relatively high initial capital, SNCR grapples with elevated reagent costs. By combining both technologies, the hybrid SNCR/SCR system achieves a cost balance over its life cycle, effectively reducing NOx emissions and optimizing reagent utilization. In comparison to standalone SCR, the hybrid approach proves more efficient in NOx reduction, particularly at lower temperatures. This can result in higher ammonia slip, but the residual ammonia is efficiently directed into a compact SCR reactor, mitigating ammonia slip and further minimizing NOx emissions.

Versatility is a key feature of the hybrid SNCR/SCR system, offering various installation configurations to suit different requirements. Examples include SNCR with a conventional reactor-housed SCR, SNCR with in-duct SCR, SNCR with catalyzed air preheater, and SNCR with a combination of in-duct SCR and catalyzed air heater. This adaptability ensures that the system can be tailored to diverse operational needs.

As governments worldwide tighten regulations to control emissions, the development and adoption of the SNCR/SCR system are poised to create lucrative opportunities for diesel exhaust fluid (AdBlue) producers. This innovative technology not only aligns with regulatory norms but also presents an environmentally conscious solution for NOx reduction, contributing to cleaner air and sustainable practices in the transportation sector.
