Catalyst Technology

HANLAN SCR Catalyst

HANLAN manufactures homogeneous titania-based ceramic honeycomb SCR catalysts for the power generation, industrial, and petrochemical industries worldwide. Our SCR catalysts are used on boilers, turbines, and engines (stationary, marine, and mobile). HANLAN has the largest installed SCR catalyst base operating in more than 1,000 SCR systems, totaling over 10,000 MW of generating capacity worldwide.

Our unique SCR Catalyst product features include:

High DeNOx removal High Mercury Oxidation rate Low SO2 --> SO3 conversion rate Low pressure drop & ammonia slip

Custom Made SCR Catalysts

HANLAN's SCR catalyst formulation and cell pitch are customized for each flue gas application, ensuring high NOx reduction efficiency and high Mercury oxidation rate at very low-pressure loss. Our honeycomb construction offers higher mechanical strength for catalyst durability in addition to an efficient geometry for high surface area and low-pressure drop. We determine the honeycomb structure and cell pitch for each customer application following an engineered analysis of system performance requirements. Our catalysts are installed in carbon steel frames for easy handling during installation and replacement. Our catalysts are versatile and can be operated over a wide temperature range and provide excellent resistance to sulfur, poisons, and erosion, resulting in long life and low overall cost to the customer.

SERVICES

CFD Modeling Computational fluid dynamics (CFD) is a way of analyzing problems that involve fluid flows. In more complicated terms, the program uses a digitally constructed model of the boiler and solves equations for a set of given inputs related to energy, momentum and chemical composition. All this number-crunching results in a visualization that displays how properties like temperature or NOx production function inside the boiler, enabling HANLAN engineers to make design adjustments easily. HANLAN has used CFD modeling since 2008 to diagnose issues related to high NOx and CO emissions, air flow distribution and fuel utilization. The model has also been employed as a routine step in SNCR design (see image in sidebar) and for determining how effective various other NOx emission control technologies will be. Our experience includes a wide variety of boiler types, including stoker, tangential-fired, cyclone-fired and opposed-fired. Even supposedly identical boilers rarely function the same, so each CFD profile is unique. HANLAN's ability to tailor a model to your specific needs means more accurate, predictable results, either with conventional technologies or solutions that are more cutting edge.
