Stack modelling and emission gas testing
IPU are total emissions solutions providers. As well as Selective Catalytic Reduction (SCR) Systems and Diesel Particulate Filters (DPFs), IPU can provide stack modelling services to ensure your site as a whole is compliant and accurate emission gas testing.
- Emissions Gas Testing
Gas testing will soon be essential. As part of The Environmental Permitting (England and Wales) (Amendment) Regulations 2018, all gensets will need to be registered and get a permit. This must be done, regardless if the genset is used for standby or prime power. As part of this permitting, the emissions values of the genset must be recorded.
Many gensets will have a datasheet available with them, which may include some emissions values. These emissions values may not be accurate if the genset is older, but DEFRA will accept a datasheet from the engine manufacturer.
However, it is likely many older engines will not have an emissions values datasheet available. In these cases, gas testing is essential.
Gas testing costs £2,200 for one day in England and Wales (this cost will likely increase if the site location is outside England and Wales). One days testing must be booked as a minimum.
The number of engines that can be tested per day depends on a number of factors, including make/model of engine.
- Stack Modelling
If your site sits with a Low or Ultra-Low Emissions Zone, it will be particularly important to lower emissions as much as possible.
If the site is in another sensitive area, such as near a hospital or a school, you may want to lower overall site emissions as much as possible.
Whilst installing exhaust gas abatement will ensure the engine is compliant to regulations such as the MCPD, it does not necessarily mean the site as a whole will be compliant.
The 2008 Ambient Air Quality Directive (2008/50/EC) pays close attention to concentrations of outdoor air and major pollutants (such as NOx) that are found in those areas.
Our stack modelling service will conduct a full survey of your site. It looks at terrain and meteorological data, as well as any relevant building information.
From this, recommendations can be made on how to reduce overall site emissions and improve the air quality of your local area.
