Nett Technologies Inc.’s BlueMAX™-Series Selective Catalytic Reduction (SCR) System is an advanced after-treatment technology that reduces Oxides of Nitrogen (NOx) emission up to 99% from a wide variety of natural gas and diesel engines for up to 20 MW. Using the urea solution that breaks down in the exhaust stream to form ammonia, makes Nett SCR as one of the most cost-effective ways to become complaint to Best Available Technologies (BAT), MOECC (Ministry of the Environment and Climate Change) 0102463, 4SRB SI/4SLB RICE NESHAP and Tier 4f/ Euro Stage IV. With over a quarter of century experience providing verified technologies, Nett Technologies manufacturers highly optimized SCR systems that bring forth continuous compliance to stringent emissions requirements.

Principle of operation:
In this closed-loop system, the harmful NOx emissions are reduced over the SCR catalyst through a chemical reaction with a fine mist of urea solution or Diesel Exhaust Fluid (DEF). The retrofit ready system consists of a removable SCR reactor, a control panel, and a DEF tank. The control strategy relies on a number of integrated sensors through a closed feedback loop that makes the system very suitable for all load conditions. The emission control system continuously monitors the input NOx levels and switches the urea pump to inject an adequate amount of urea into a mixing chamber where the suitable compressor provides adequate compressed air. The NOx sensor-based control strategy makes the system fully automated without the need for operator interference.

Product Options

To provide optimum performance, each BlueMAX™-Series SCR system is custom designed for the intended application. The main components of the BlueMAX™ system include the Selective Catalytic Reduction (SCR) catalytic converter, the computerized Urea Dosing System (UDS), and integrated housing including the mixing chamber and the urea tank. For diesel applications, the SCR system can be also equipped with the Diesel Oxidization Catalyst (DOC) and the Diesel Particulate Filter (DPF).

 

Silencer

Typically, the BlueMAX™-Series SCR System provides an overall 35-43 dBA sounds reduction. Further sound attenuation up to 55 dBA is available upon request. Please contact one of our representatives for further information.

 

Diesel Oxidation Catalyst

Precious metal coated Diesel Oxidation Catalyst (DOC) can be installed upstream of the SCR unit. The DOC core is made of corrugated, high temperature resistant stainless steel foil, packaged into rugged stainless steel containers. The DOC oxidizes Carbon Monoxide (CO), Hydrocarbons (HC), partially the Particulate Matter (PM), and aldehydes contained in diesel exhaust to non-toxic compounds: carbon dioxide and water vapor.

Diesel Particulate Filter

As an additional option, our BlueMAX™ SCR system can also include either a Passive Diesel Particulate Filter or Active Diesel Particulate Filter. Passive filters are generally utilized on engines that operate under heavy loads, while active filters are used on engines that have a lighter duty cycle. Electrical Heater and Hydrocarbon Injections are used to increase the exhaust temperature for the active regeneration.

 

Electrical Heaters

When the temperature is not sufficient for passive regeneration, a set of electric heater coils are used to increase the exhaust temperature for active regeneration. An Electronic Control Unit (ECU) evaluates the system parameters such as temperature, pressure, and exhaust mass flow rate in real-time and uses these values to predict and activate the regeneration cycle.

 

Monitoring System (GUI)

BlueMAX™-Series SCR consists of a monitoring and alarm system with a color display that will log all the data from the system and inform the operator about system parameters such as filter load level, exhaust temperature(s), and pressure. The system is also equipped with an alarm that will notify the operator about any system issues/errors such as sensor malfunctions. It can provide several digital signal outputs which can be connected with any existing alarms or indicators.
