Installation

A solution comprising of fourty of NOxProtekt 600-3 Selective Catalytic Reduction units supported by a frame structure allowing for thermal expansion and vibration isolation, with an upgraded modernised exhaust pipework. Each pair of units were controlled by a urea control panel directly linked to the main system panel which was in turn connected to the site generator control system. A pressurised piped ring main containing urea fed via a bulk storage tank completed the design. The site was limited in terms of space and installation was conducted under rigorous COVID restrictions.

Summary

The installation was a successful example of a quality engineered solution provided to give a turnkey solution for compliance with greater autonomy and reliability.

Objective

To Provide emissions abatement solution to 14 number 1,500kWe diesel generator sets on a Capacity Market STOR site allowing it to be operational whilst still complying with Medium Combustion Plant Directive (MCPD), and the Environmental Permitting Regulations (England and Wales) January 2018.

Installation

The turn key solution comprising of single SCR on the roof of the existing generators. The challenge included providing a solution that would minimise any disruption to the existing critical back up power generators. We achieved this by designing SCR system that are mounted onto structural spreader beams directly onto the roof of the building and suitable AdBlue bulk storage tank that is neatly suited between existing fuel tanks for ease of refilling during operation. The locally wall mounted individual dosing panels & common control panel were cleverly designed to allow for site expansion should an additional generator be required on the site. The SCRs communicate directly with the site generator control system to ensure automatic start up & shutdown.

Summary

The installation was a successful example of a quality engineered solution provided to give a turnkey solution for MCPD compliance, structural calculations for roof installation and seamless connection to customers existing generators. No temporary diesel generators or load banks were required during any part of the installation or commissioning.

Installation

The turn key solution comprising of single SCR connected to a new P550-3 generator fitted with Perkins 2506A E15TAG2 engine situated on the ground floor of a 12-storey Grade A 7,000 sq ft office building in Hammersmith Central London. The challenge included providing a solution that would achieve the very tight NOx emissions set down by the Local Authorities Borough of Hammersmith & Fulham, this correlates to half NOx levels required by the MCPD.
We achieved this by designing a high-performance SCR system that incorporates specialist catalyst selection while focusing on the available back pressure in the engine exhaust system. The generator package provided by our customer included very high acoustic attenuation achieved with primary & secondary silencing combined with engine acoustic housing. NOxProtekt Ltd provided peace of mind with detailed pressure drop calculations that fit in with the engine constraints.
As a turn key system provider we included a local AdBlue storage tank locally wall mounted individual dosing panel & SCR control panel which neatly sits together in a compact space below the SCR reactor & pre-injection pipework. The SCRs communicate directly with the site generator control system to ensure automatic start up & shutdown.
Furthermore NOxProtekt worked alongside a MCERTS accredited NOx emission testing house to complete a commissioning report & documentation specified by the customer & the Local Authority.

Summary

The installation was a successful example of a quality engineered solution provided to give a turnkey solution for MCPD compliance, MCERTS accredited emission testing and additional site specific NOx emission to atmosphere limits and seamless connection to customers new generator package right in the heart of London.
