NOxMASTER™ SCR Dosing System Upgrade | Natural Gas CHP

“Out with the old, in with the new!” exclaimed our customer, when it was established that the SCR system which was purchased some years ago from an overseas supplier - simply did not work!

The Agriemach emissions team were invited to a London energy centre to solve the challenges our customer was facing. An SCR system their projects team purchased from overseas which had no visualisation; no screen; no real way to establish what the SCR System was doing – other than it was constantly in fault. This was of course preventing the CHP from running, as the client needed their emissions to be in line with their permit conditions for grid linked power generation.

In addition to these issues, the AdBlue tank was also far too small for the application – completely undersized and not fit for purpose. The challenge here is that the energy centre is basement (Level -2) which certainly does not allow for storage tanks to be delivered in one piece, when the only access point is a stairwell!

The “brief” was clear – the solution was discussed, agreed and implemented.  

Agriemach removed the old SCR dosing system and installed a new NOxMASTER™ SCR Dosing Systems with full touchscreen visualisation for both RAW & Treated NOx Emissions, Backpressure, Exhaust Gas Temperature & Dosing Load – all Data Logged, along with BMS Modbus connectivity for ease of emissions reporting. 

The emissions team also installed a 4000 litre AdBlue suitable, sectional tank with remote tank level telemetry. This additional capacity increases the time between AdBlue tanker deliveries in this built up area of London which also has the added benefit of reducing the “per litre” consumable cost.

Commissioning saw the NOx target achieved on the first pass; enabling this CHP to synchronise with grid and generate power well within its permit conditions!

Not only that; they now have UK based support to ensure that the system is maintained correctly and ensuring continual uptime. A very happy customer.
