Selective Catalytic Reduction SCR

Agriemach Ltd offer a bespoke service for the design , manufacture and project management of Selective Catalytic Reduction Technology. Offering a wealth of experience and a global knowledge base, we offer full system design, Dosing System upgrades, Catalyst Replacement and all ancillary equipment required from bulk urea tanks to Heat and Sound Insulation Materials. We have experience with many different fuel types and the issues associated with them - from Natural Gas to Bio-Fuels, we are able to provide a solution for the most challenging applications.

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 NOxMASTER™ 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:

  1. Controlled Atomising Injection of Urea - Dosing
  2. Efficient Mixing in the Exhaust Stream – Static Mixers
  3. 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

Experts in NOx Reduction

Agriemach (established in 1976) have been specialists in the emissions field since 1990. It is important that when new legislation is introduced, that operators who do not necessarily understand SCR technology, do not get misled and find themselves falling into a money pit of extras after the project has started. Agriemach offer complete solutions, services and aftersales support. We are always here to advise our customers, and ensure that the information being provided to them is accurate – this is why we offer our CPD presentations, because we want you to understand and feel comfortable with the product.

1. We have example installations across the UK and Europe
2. We have our engineering department at your disposal to offer you the best design for your application
3. We have chemical engineers on hand to recalculate the confusing NOx limits that we see time and time again, all with different oxygen reference
4. We have our site service engineers available to assist you if you ever have a question or concern.

What our customers say

"I would like to say thank you for your help on this project. Things have not always been easy, and we have had a few challenges, but you (both corporately and personally) have conducted yourself with integrity at all times and have made things a lot less painful than they could otherwise have been for us."

"In a few years’ time I am sure the birthing pains will have been forgotten and the investment we made will have delivered the anticipated benefits – and I am confident that the level of emissions we put into the atmosphere will not give anyone cause for concern."

"Good luck in future projects."
