Services-Framework- IED - Leakage Detection and Repair for biogas facilities

Description

The supplier will engage in a service contract, focused on providing Leakage Detection in line with the Industrial Emissions Directive (IED). EA BAT guidance dictates that the scope for LDAR is sources of leakage of Volatile Organic Carbon (VOC’s) including methane. (Biological waste treatment: appropriate measures for permitted facilities - 11. Emissions control - Guidance - GOV.UK) The following type of assets are included but not limited to the LDAR scope; · Double membrane roofs (air blower vent) · Roof and cover fixings · Pressure relief valves and vents · Feeding and digestate separation units · Gas pipes · Conveyors and presses · Compressor · Combined heat and power plant (methane slippage) · Gas upgrading plant · Reception storage · Digestate storage · Pits and sumps, for example condensate pits Testing Method The Bioresource and Energy Services team require surveys to detect fugitive emissions of Volatile Organic Compounds (VOC’s) and other substances to air including methane. The LDAR survey methodology must fully comply with EA guidance Biological waste treatment: appropriate measures for permitted facilities (2024) Section 11.9 - Leak Detection & Repair and currently utilise the Optical Gas Imaging (OGI) hand held camera method to enable visualisation of gas leaks with quantification of emission rate and emission concentration.
