NOxMASTER - Model SCR -Selective Catalytic Reduction Technology for NOx Emissions
Agriemach Ltd specializes in the design, manufacture, and project management of Selective Catalytic Reduction (SCR) systems aimed at reducing NOx emissions. Their services encompass full system design, dosing system upgrades, catalyst replacement, and provision of ancillary equipment such as bulk urea tanks and heat and sound insulation materials. With experience handling various fuel types, Agriemach can deliver solutions tailored to challenging applications. Utilizing 3D CAD drawing services and Computational Fluid Dynamics (CFD), they ensure the proposed solutions meet client needs. SCR technology targets NOx emissions specifically, converting them into nitrogen and water through urea injection and catalysts. The system includes a PLC for comprehensive monitoring and control. Established in 1976, Agriemach has been a significant player in the emissions field since 1990, supporting customers with accurate information and comprehensive aftersales service, thereby ensuring compliance with evolving legislation.
We offer a full 3D CAD drawing service along with Computational Fluid Dynamics (CFD) to ensure our solution is suitable for your requirement.
The efficiency of our NOxBUSTER™ technology is second to none.
What is NOx?
Nitrogen Oxides are a hazard to human health. Scientific evidence links NO2 (Nitrogen Dioxide) exposure, ranging from 30 minutes to 24 hours, with adverse respiratory effects including airway inflammation in healthy people – to increased respiratory symptoms in people with asthma. Ozone or Smog is formed when NOx and Volatile Organic Compounds (VOCs) react in the presence of heat and Sunlight. These particles affect anyone that comes into contact with them – they get deep into the respiratory system and alter lung tissue; causing a long term effect on human health.
Most susceptible to these are children, the elderly and people with existing lung disease. This is the motivation for legislators to lower the limits.
What is SCR?
Selective Catalytic Reduction is a means of converting Nitrogen Oxides (NOx) into Nitrogen and Water, using an Atomised Injection of urea with the aid of a Catalyst.
How is it achieved?
The reduction is called “Selective” as it is only targeting the NOx emissions using the reagent and Catalyst. We take the Raw NOx Value and Reduce it to the Target Value (500mg to 50mg – 90% Reduction)
This is achieved through:
- Controlled Atomising Injection of Urea - Dosing
- Efficient Mixing in the Exhaust Stream – Static Mixers
- Vanadium Coated Catalyst Surface - Reactor
System Overview – Monitoring and Control
The PLC (Control Panel) monitors and controls the entire system:
- Engine Load levels
- Raw NOx Level
- Treated NOx Level
- Temperature
- Backpressure
- AdBlue Level
- Compressed Air
- Dosing Pump
