Selective Catalytic Reduction | Power Generation
Agriemach have had a busy start to 2015 with one of our SCR (Selective Catalytic Reduction) applications being commissioned in January. The Crossrail site at London’s Canary Wharf will be one of the largest Crossrail Stations. Like the nearby Canary Wharf Tube Station, the new Crossrail station is being built in dock water area, in this case the North Dock of West India Quay. Agriemach have supplied the NOx Abatement Equipment for the CHP exhaust gas at the new Crossrail Station which – along with a proposed retail park and areas – will be six storeys high, approximately the size of One Canada Square effectively laid on its side.
Selective Catalytic Reduction (SCR) is a means of converting Nitrogen Oxides (NOx) in exhaust gas, into Nitrogen and Water using an atomised injection of urea (AdBlue) with the aid of a Catalyst. The systems are used on Lean Burn applications and offer a very high efficiency for the reduction of Nitrogen Oxides.
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 with children, the elderly and people with existing lung disease being the most susceptible.
This particular CHP SCR system was commissioned on the 14th January 2015 and provided a required 90% reduction of NOx, making the emissions from this CHP much cleaner and the surrounding air far better for the vast numbers of passengers due to use this station. A stable reduction down to 23 parts per million of NOx was set up during Hot Commissioning which has exceeded the customers expectations.
Agriemach offer a fully comprehensive service to the stationary engine market and part of this service includes giving technical training to engineers, project managers and service engineers in order to share our knowledge over the products we sell to the market – a service that is crucial to maintain a broad confidence in customers throughout a market where technology is always changing.
